love them but didnt fit my 320 x compact
Brad Bordon (verified owner) –
Fits great, way better than the factory mag well. Low profile and helps with my grip and reloads.

This magwell was a little tight on my p320 Spectre comp due to the Cerakote paint but I got it to fit and it looks great, much better than the stock magwell that looks bulky and extends down making the pistol look too long… I’m a very happy customer… Thank you Killer innovations…

Perfect size. Not too large. Streamlined design. Fitment was perfect. No gaps. The color matched the cerakote as well.

It fits perfect on the sig p320 xfive legion, it feels amazing in your hand and it offers a great way to drive your magazines in, the lower profile is simply amazing if you’re considering to have this as a carry option.
