Before we get into the review, it's come to my attention that the model we have is slightly different from the P320 XCompact previously sold. The new model retains the rear sight when using an optic. The SKU (part number used to identify this specific model) for the P320 XComact as we tested is: 320XC-9-BXR3P-R2.
As you've by now noticed in our other articles and videos, the Fire Control Unit (FCU) concept of the Sig P365 and P365 is a fun one. The serialized part is the trigger assembly and it's tidy chassis meaning that we can slap whatever grip we want onto the gun, and with interchangeability among families of guns you can turn any P320 into any other P320 model without going through the hassle of another complete firearm. We got into this with an article I wrote for a magazine about the P365 FCU. Now it's time to enjoy the P320 FCU, but that requires (and ironically less expensive) if we start with a complete firearm and modify from there. Enter the Sig P320 XCompact to the GBGuns Armory.
The XCompact fits about in the sizing we've come to know as "compact". 15-rounds of 9mm, but with a slightly shorter barrel of 3.6" rather than the normal 4". Why do this if most ammunition is loaded to perform from a 4" barrel? Appendix carry. As the trend grew of folks shoving pistols in the front of their pants it was quickly discovered that not all hip areas could comfortably accommodate the ideal 4" or longer barrel and slide. Sig's response was to release a model slightly shorter, but still provide the standard 15-round capacity and grip size that is a more universal hand fit than a subcompact frame. This gun is a bit of a mullet gun. subcompact-size barrel, compact grip, a bit like the Walther PDP-F we've also covered.

Additional features that inspired us to go for this "X" model include the flat trigger face and Sig's excellent X-Ray night sights which have proven to be excellent target sights in the daytime. The tabletop video below shows more detail and what all comes in the box.
As polymer-framed, striker-fired 9mm pistols have become so ubiquitous they've also become a bit boring. We weren't expecting anything magical from the gun when we hit the range, just a good quality pistol. Our impressions however changed once we started shooting.
Ammunition seen in our Shooting Impressions video was made possible by our Patrons and supporters of our ammunition savings account through Ammo Squared. Additional, on-demand ammunition through True Shot Gun Club.
On the range the XCompact was delightful to shoot. The trigger was predictable, recoil surprisingly manageable for a pistol of this size, and sights proved excellent once again. I have no doubt that part of what made it such a nice shooter are the very same statistics that have some question if it's a good carry gun: the XCompact weighs more and a wider than most of it's competitors. That makes for an easier-shooting gun at the expense of possible cancelability and carry comfort. Which direction is right for you will depend on your needs and intent. I prefer to carry something I shoot well, trading carry comfort for carry confidence.
In the Future, you can expect to see more coverage of this FCU as we experiment with other offerings both from Sig and the aftermarket. We've got a couple configurations already in mind and it's fun to be able to so easily swap the FCU from grip module to grip module and experience a new "gun".
I’ll say the FCU concept is fun! I love my “XCompact”. It’s a terrific size and smooth shooter but I have to admit it’s an older P320 Sub Compact that has the XCompact grip module and XTrigger that I got as soon as they became available. Don’t hate me for having a faux XCompact, I had to switch my older P320’s to the X style after I got my X Carry and I’m glad I did. The X grip fits my hand so much better!
I bought one when they became close to affordable, and mine is the earlier version - I'd have to remove the rear sight (from underneath) to mount an optic, and mine came with a little pop-up LCI your pistol doesn't have. I also went with the Wilson Combat grip module / tungsten weights - it feels comfortable and well balanced in my hand.
Well done 👏.
Mirzon makes a nice looking grip module in any color too.
There are alot of companies that sell x compact & x carry grip modules. You can get them stipple & cerakoted in about any color combination with any kind of stipple texture you want. I have considered getting the tin fcu just to build one. I think lfa, live free armory has the best deal on rmr cut 320 slides. Looking forward to see what the gb guns channel does with the fcu. Options are pretty much unlimited.
