This grip will allow your 9mm 2011 handgun to accept 17 round and larger Sig P320 magazines.
Includes: grip, mainspring housing, grip screws, grip screw washers, trigger overtravel pin.
Uses OEM or aftermarket Sig P320 magazine release (not included).
Uses OEM 2011 components from your handgun (trigger, sear spring, mainspring).
Grip width and length is comparable to OEM Sig P320 grip which is noticeably smaller than 2011 grip.
The handgun can be converted back to the OEM 2011 grip at anytime.
There is a small chamfer that needs to be made inside of the gun's frame to give clearance for the magazine. This can be done with a Dremel and then dabbed with cold bluing. The chamfer does not affect strength, function, or ability to convert back to OEM. See assembly information page for more info.
