- Do not worry, we have some ideas to help! Please check out this video on breaking in our barrels and slides:
- Our barrels and slides are plated with an extremely hard finish that uses the PVD coating process. These finishes, when new, can be micro abrasive and require a break in period to burnish the finish into other metal contact areas. We suggest using grease lubrication on all metal-to-metal contact areas on the barrel and slide to help this burnishing process along.
- Killer Innovations recommends using Lucas Red n Tacky #2 Grease during break in.
- We do not recommend you run our compensator until this break in has been done. It will usually take 300 to 400 rounds to completely break in.
- During this break-in period, you will get misfeeds and failures to feed. This is normal and should stop once your barrel is fully broken in.
- If issues persist, make sure you are using an OEM connector and safety plunger as some aftermarket parts can add excessive drag and cause feeding issues.
- If you are still having problems, please contact email@example.com, or call our office at 844-214-8622 for assistance.
- We recommend a good quality 115 grain ball ammo to get the best performance out of our barrels. We use American Eagle and Herters ammunition to test with in the shop.
- +P Ammo will also work well in our accessories.
- We do not recommend using reloads or non-brass cased lead ammo, as these items can damage your barrel.
Single process technology
killer innovations has developed what we believe to be the most accurate pistol bore manufacturing process ever created. s.p.t. stands for single process technology and single point technology. single process technology means the bore, rifling, and chamber are cut in one high precision machine without human interference.
What it means…
single point technology means the rifling is cut using the legendary and painstaking single point cutting technique. this single point cut rifling process requires a single cutter to make 120 individual cuts to accurately rifle each bore. single point cutting yields identical grooves that have less than .0001” deviation between each other because they are being cut with the exact same cutter.
- Double check that the compensator you purchased is compatible for your model of firearm. Our compensators must match the make, model, and generation of your firearm for successful installation. Please refer to compatibility guides on the specific product pages if you have any questions. Our compensators are designed to work only with the specifically listed firearm makes/models/generations.
- Please watch this video covering common issues that can occur during compensator installation: https://www.youtube.com/watch?v=PBEC00vg3js
- Ensure that the rubber O-Ring and thread protector were removed from your barrel prior to installation. The threads on your barrel need to be right hand ½-28 thread pitch and extend to the end of the barrel.
- Check that the locking ring is tight. Hold the button on the compensator all the way in and turn the threaded ring by hand to check for thread tightness. Ensure there is no “clicking” noise from the ring during this procedure.
- Ensure your guide rod is a match for your firearm and is in good working order. If you are running our compensator on a Glock 19, we recommend changing to a 13 lb spring.
Are Your Compensators Interchangeable? Can I Use A Gen 3 On A Gen 4, Etc? Can I Use It On A Different Model of Firearm Than What Is Listed?
- Our compensators are designed specifically for the stated model and generation of firearm. The dimensions and guide rod requirements differ from generation to generation and model to model, and as such our compensators cannot be used interchangeably. Please ensure you purchase the correct model and generation to match your firearm needs.
- For the Socket Cap screw on the bottom: 7/64 Allen Wrench
- For the set screws: 5/64 Allen Wrench
- It sounds as if a little too much thread locker was used during installation. Firstly, remove the screw from the bottom of the compensator. Pry it out gently, then clean the thread locker residue from the parts and hole with some alcohol and a Q tip. Use a small amount of blue thread locker when reinstalling the screw (too much will glue the button in place once it dries). Tighten the screw until the button will not move, then back off on the screw until the button moves freely.
- Please make sure the gun is unloaded and safe before starting this procedure. If possible, have someone help you by holding the gun firmly during this process.
- If available, use a heat gun to the warm the locking ring.
- Using two narrow strips of duct tape, stick the strips over the locking ring in two layers.
- With a pair of channel lock pliers grab onto the locking ring with the contact points at 3 & 9 o’clock from the top. Make sure to adjust the pliers so the jaws are parallel when grabbing onto the locking ring.
- Push the compensator button all the way in and firmly rotate the locking ring in a counterclockwise direction. Be very careful not to gouge the aluminum compensator body.
- Once the ring has been removed, clean the thread locker residue off the barrel threads and locking ring with lacquer thinner.
- We have a helpful video available that goes over some common issues when running a compensator.
- A compensator is designed to take the gases released from firing ammunition and redirect them in a way that is more advantageous to the shooter – resulting in flatter shooting and faster follow up. However, the compensator robs momentum from the slide action during this procedure. Always be sure to run high quality ammunition to ensure enough cycling power on your firearm with compensation.
- We recommend using American Eagle 115 grain ball, or Herters Ammunition.
- Ensure your barrel and slide are fully broken in before attempting to run a compensator.
- If you are still having issues, please contact firstname.lastname@example.org, or call our office at 844-214-8622 for assistance.
- The simplest method to clean our compensators is to disassemble them, and clean with gun solvent and picks/brushes.
- We also recommend ultrasonic cleaning.
- We include two different locking rings with your compensator to allow you to tailor your shooting experience to your needs.
- Full Compensation: the smaller or thinner ring will yield full compensation to your firearm. This means you will experience less recoil and muzzle rise and help give you more accurate and faster follow-up shots. However, this can also mean your firearm may be a bit more temperamental. It will need to be cleaned regularly, used with good quality ammo, and patience will be needed during break in.
- Reduced Compensation: the larger or thicker ring will do much the same job as the smaller ring, just to a lesser extent. Also, with the reduced compensation ring in place your firearm will be less temperamental – it will run more consistently with some neglect or poorer ammo. However, it won’t be as effective at reducing recoil and muzzle rise.
- The overall measurement of a Glock 19 Gen 3-4 from the back of the slide to the front of the compensator is 8.19”. For a Gen 5 it is 8.23”.
- Safariland Holsters will work with our compensator set up; however, they will need to be modified by cutting off the end and removing the spring from the retaining latch.
- Killer Innovations recommend holsters with the “infinity” cut – i.e., open bottoms to work the best with our compensators.
- We highly recommend Gerber Holsters, as they are producing a holster designed for our compensator setup:
- Killer Innovations also offers our own specially designed holster made to work with our products.
- Unfortunately, none of the holsters Killer Innovations offers are set up to work with flashlights or light bearing. We recommend contacting Gerber Holsters to address this specific need.
- Double check that the Magwell you purchased is compatible with your model of firearm. Some aftermarket items (such as Poly 80 frames) may need modification to allow the Magwell to snap in place.
- If your firearm has been stippled or cerakoted, it is possible some extra material may be binding up the Magwell. Double check that there is nothing preventing the Magwell from sliding on.
- Heat from cerakoting can also cause your grip to expand and the magwell to not fit properly.
- Killer Innovations Glock 17 and 19 Magwells come with 2-3 Magwell Plugs.
- Magwell packages containing 3 magwell plugs are designed to work with Gen 1-3, Gen 4 w/ Backstrap, and Gen 4 w/out a Backstrap.
- Magwell packages containing 3 magwell plugs are designed to work with Gen 1-3, Gen 4 w/ Backstrap, and Gen 4 w/out a Backstrap.

The Glock Magazine Extensions Come With Springs. Why Don’t the CZ and Sig Magazine Extensions Include Springs?
- Our CZP10 and Sig P320 magazine extensions were designed specifically to work with existing magazine springs, and as such do not include replacement springs with purchase.
The Screws That Came With My Trijicon Optic Are Too Long, And The Screws That Came With The Slide Are Too Short For Install – What Do I Do?
- We have great news! We have a Custom RDS Screw kit that is made specifically for our slides. You can find it here – Custom RDS Screws – RMR/Holosun
- Our Velocity slides are sold stripped, and do not include channel liners.
- We recommend OEM upper parts kits to complete your slide build.
- Our slides are designed to work with Iron Sights, and Red Dot Sights (specifically Trijicon RMR and Leupold Delta Point Pro). Please check out the instructions for each firearm model located here: https://killer-innovations.com/instructions/
- Reference Section 4 for Iron Sights
- Reference Section 5 for Red Dot
- Killer Innovations recommends Night Fision Sights https://www.nightfision.com/
- Installation video can be found here: https://www.youtube.com/watch?v=pcMNUv7Cv_g&t=2s
- Our slides are compatible with the Holosun 507 series if you are looking for a direct bolt-on option.
- Our slides are also compatible with the 509 series; however, this version has a dovetail style mounting system that will require an adaptor plate. Holosun provides an adaptor plate with the 509 series, and this plate should fit our slide RMR bolt pattern.
- Unfortunately, the Sig Romeo 1 sight will not work with our V1 or V2 slides. While the bolt pattern is similar to the Leupold Delta Point Pro Series, the length of the sight is just long enough that it will not fit in our footprint.
13lb Spring Kit
- Our 13lb Spring kit is recommended for running our compensator on a Glock 19. Included is an adaptor ring to use the 13lb Spring Kit on a Gen 4 firearm. If you have a Gen 3, you will not need to use the adaptor ring.
- The adaptor ring will snap easily into the guide rod hole on the end of your Gen 4 slide.
- Due to the demands of our own product lines, as well as time, tooling and programming costs, Killer Innovations is not able to offer customized items. All our accessories are made in-house from start to finish – we do not modify existing OEM parts. We are not able to customize personal slides or other items with our designs.
- We would love to offer custom colors or variants on our items, but it is not something we are set up to do at this time.
- Killer Innovations uses a PVD Coating Process for our slides and barrels, and anodizing for our other accessories (magwells, base pads, triggers, magazine extensions, compensators, back plates). As we do not use cerakote, we are not able to suggest appropriate color matches for our items. We recommend talking to a cerakoter in your area for more information.
- Due to the differences in the metal composition and finishing processes of our accessories, we cannot guarantee exact color matches between our items. For more information, please see our full explanation located here:
- Killer Innovations parts will work with the Polymer 80 lower kits, however getting everything up and functional may take more time, trial and error and work than a traditional OEM Glock part replacement. Killer Innovations parts and accessories are only guaranteed to work with Killer Innovations parts and OEM Glock Parts. Compatibility with other aftermarket parts is not guaranteed.
- Killer Innovations is not able to troubleshoot every issue that may arise while creating a Polymer 80 build. We recommend researching tips and techniques thoroughly before beginning your build, and if you run into trouble (unrelated to the function of our specific parts), please consult a qualified local gunsmith.
- Many of the guns featured on our Instagram and Facebook pages are submitted by our media partners, enthusiasts, and by our valued customers. We love seeing all the creative ways our accessories are used in your personal builds!
- Most of the photos are tagged with the maker or builder who created the custom build, and we encourage you to reach out to them for more information on something that has captured your interest.
- We recommend checking out companies such as Rainier Arms (https://www.rainierarms.com/) for a wide variety of both specialized and OEM parts and kits to ensure the best from your builds. Always have your parts inspected and installed by qualified armorers. When in doubt, we recommend OEM parts kits to ensure compatibility.
- Killer Innovations guarantees our items will work with OEM parts, and with our own accessories. There are just too many variations in design and tolerances between various companies for us to test and verify every item.
