Rated 5 out of 5 by Susie Q from Great fit and function I just installed the medium X-Compact grip on my P320 Compact today. Big improvement over the original grip - a great fit in my hand. Bonus, It looks good too. The fire control assembly and slide fit the grip perfectly. I also like how the X-Compact works with the TLR-8. I used the TLR-8's 1913-3 rail key, which caught the forward rail cross groove of the X-Compact grip. Sig customer support was very helpful (as always) when I called with a question about 3 of my 10-round magazines. The ones with the "Sig Sauer" base plate don't work, but the ones with the round "Sig" logo work perfectly. They are sending me replacement plates for free. Bravo, Sig Sauer.

Rated 5 out of 5 by Buck hunter from The ergonomics of the grip a outstanding! I ordered the Xcompact grip module a couple of months ago to mate with my Xcarry and I'm truly glad I did. It has a better feel in the hand and much more manageable if shooting one handed. I don't have small hands, I guess I am somewhere in the middle, but the Xcarry grip module was a little much for one handed shooting but felt great when using both hands. I don't have a negative thing to say about either grip module because they really are better even than the standard p320 grip module. But if you have wide hands but not really long fingers to really get a good purchase on the larger module you should definitely try the Xcompact grip module.

Rated 5 out of 5 by Matt in NC from Older compact magazine floor plates won't fit. I purchased a P320RX Compact in early 2018 and it came with two magazines. The two original 15rd magazines that came with the gun have slightly wider sides on the top of the floor plate and won't seat into the X-Compact grip module and are incompatible. A newer 15rd magazine I purchased separately from the gun has narrower sides and does fit into the X-Compact grip module. Round button on floor plate is old style, square is new. Both of these floor plate styles fit into the original P320C grip module with no issues. If you have the older style magazine floor plates with the wider sides on top, you will have to order the newer floor plates as well for your magazines to be compatible with the X-Compact grip module: https://www.sigsauer.com/store/p320-p250-floor-plate.html

Rated 5 out of 5 by Zac405 from The superior engineering of the 320 dominates. At the time I ordered the x compact grip module I had planned on coupling it with my compact 320. When I recieved it and mount the 4" slide it fit fine with a little stick out on the slide. Great grip that fit my hand fine with good ergonomics. However I also have a 320scr with a 3.5" slide. This slide fit perfect making the sub compact the best of the 320 being able to go from and oversized pocket gun to a 15 round fighting pistol. I've function test both slides with 500 round of cheap steel ammo with zero malfunctions. With the killer prices for the subcompact 320 combined with an X grip module. The superior engineering design of the platform is as clear as day. I'm reminded once again why I chose this platform. With $50 you can completely change the unit as needed.
