Just what the Doctor ordered.
I was looking to spruce up my gun so I ordered several of these with military themed images. They are perfect. Function is just like OEM but they look so much better!
-
super easy install
Color is great. Design is super clear. Very easy to install. Only negative is that the tabs, which mimic Sig's will not allow use of these baseplates with the X series compact grip module I have.
-
Excellent Quality, Fit and Fare... and Service too
Excellent product quality. So good I bought more for another pistol to match.
-
Nice touch
Wanted to be able to Identify my magazines during training class. As all magazines look similar the base plate makes it so easy to see which ones are mine. The added engraving is just a nice touch.

Item looks great but does not for the p320 mags
ordered a back plate and base plate for my sig p320 and the magazine base plate does not work. It is wrong for both the US made mags and the circle sig mags

p365 finger extension
Well made and help with mag release. Looks great too.

Compatibility issue
Unlike the original SIG P320 mag plate which fits all Sig Grip modules, this floor plate has fat "lips". As a result, the magazine won't fit into either X-Carry or X-Compact grip modules. Otherwise, the plate is well-designed and of high quality. It's said to be universal (like the original SIG part), but it can only be used with SIG's classic grip modules (Full, Carry, Compact, M17).
