The Wilson Combat Sig Sauer P320 has been around for a few years. I purchased mine toward the end of 2020.
Since then, I’ve put about 4000 rounds through it. Not as many as I’d like, but enough to get a good feel for the gun.
I ended up with the Wilson Combat Sig P320 because Wilson Combat had the only P320 model available to me at the time. The Sig P320 line was the latest hot striker-fired pistol platform.
Because 2020 was a dumpster fire of a year, finding a Sig X5 series full, or even mid/carry size, was going to be tough.
I would have bought a standard model, but I wanted a little more in the performance department, so the hunt was on.

First Impressions & Features
The hunt led me to the new P320 from Wilson Combat, which wasn’t even on my radar.
When I saw it there under the glass at the gun shop, I was intrigued, to say the least. Of course, I knew who Wilson Combat was, having crossed paths with several of their firearms over the years and always having a good experience with them.
I’ve long considered guns to be tools used to do jobs. That said, a man can never have enough tools and certainly should not have to hunt one down like he’s searching for a damn Cabbage Patch doll in 1983.
Wilson Combat Grip Module
So there I was at the gun shop checking this thing out. Based on my previous casual experience with the Sig P320 platforms, I first noticed the custom Wilson Combat cut grip module.
As good as it looked, it felt even better in my hand. I could literally feel my double and triple taps tightening up right there at the counter. I really mean it!
They did a great job. The stippling and material reduction felt great. Last but not least, the beveled mag well was pure perfection, in my opinion. Sleek, minimal, and to the point.
Wilson Combat P320 Slide
From there, the beautiful slide work compliments the frame nicely.
This pattern is known as X-Tac, which reminds me of a diamond plating of sorts. The cocking serrations run along the front and back of both sides as well as across the top for establishing functional grip, as needed.
Though beautiful as it was, I was disappointed to see that it wasn’t optic-ready. I guess I will have to pick up a new slide in the future for a red dot.
The Sights
The next thing I noticed was the sights.
Wilson Combat went with a red fiber optic front sight matched with a U-cut or combat-style rear sight. This is the Wilson Combat Battlesight, which is also available on other offerings.
Not what I was expecting, but I am more than happy with it. These sights are designed for fast from-the-holster target acquisition at close to medium ranges. Basically, 25 yards-and-in combat shooting.
Great sights, but I figured a full-size should have more precise sights.
Wilson Combat P320 Trigger
Next up was the trigger. This is by far the biggest upgrade from the Sig factory models I noticed.
As much as I love the grip module, the enhanced trigger or fire control unit (FCU) by Grayguns is truly next level.
Sig offers the standard and X5 model FCUs, which are both good. In fact, the standard model is now “the standard” for our Armed Forces moving into this new post-GWOT era.
The X5 trigger gives you a little more in the performance department. When you need to land those farther, faster shots on the range, the X5 trigger will get you there.
That said, the Grayguns trigger job is considerably better. It is a bit on the light side for a combat gun, in my opinion. The pull comes in at just 3.2 pounds on average, but what the hell, that’s why we train.
The Cost
So, I bought the damn thing. Deciding which color was a no-brainer considering black-on-black was all they had. I later purchased the tan grip module. Out the door with a third mag, it ran me just over $1400, which was money well spent. Daddy needs his tools!
On the Range
Right out of the box, a standard cleaning and lube job was given. From there, I began the break-in process with a 124-grain FMJ ball and some of Myles’s reloaded ammo.
For the first 200 rounds, I had a stoppage every other mag or so. Always a failure to feed.
Maybe I should’ve done a better job cleaning the mags. By the end of the day and 500 rounds in, it wasn’t giving me any more problems.
The sights are great for combat-style shooting. I’ve run similar U-cut combat variants on some of my Glocks, so I was used to them.
The trigger was a bit of a different story. I grew up with mid-20th-century handguns, like 1911’s, revolvers, and .22s. You know, nothing fancy.
My professional career has been mainly with Sig P226 series types with some Glocks and HKs mixed in from time to time.
So this is my first experience with a trigger this nice. Yes, I own and grew up around match 1911s, but this is a different animal. I remember thinking to myself, “What a cool problem to be having, not being able to run this gun as well as a standard service-grade pistol.”
Well, long story short, we got to know each other, and the relationship has really taken off.

Closing Thoughts
- It looks and performs great
- Excellent grip module
- Greyguns fire control unit
- X-Tac slide pattern
- Flared magwell
- U-notch rear sight is not as accurate at a distance
- 500-round break in period
- Not optic-ready
Overall, I have to say, “Worth It!” I’m very happy with this purchase, despite several cons. The pros of the Wilson Combat Sig Sauer P320 outweigh them by far.
Everyone that shoots it wants to upgrade, plain and simple. You will pay a little more for this gem, but you won’t regret it.
The additional features by Wilson Combat do deliver, in my opinion. A best-in-class performer.
