By now most all of us have heard about the Sig P320 M17 pistol. Some people might be unaware of just how modular the system actually is. Hilton Yam over at 10-8 Performance Lab was one of those folks. He had heard of the P320 but was resistant to it because of his love of the 1911 platform. He took a deep dive in a two-part video and broke down his experience with the Sig P320 M17.
Hilton Yam at 10-8 Performance Lab is no stranger to a good pistol. Being retired law enforcement, active competitive shooter, and instructor, he’s had his hands on lots of different systems. After the initial resistance and shooting the pistol stock, he was pretty impressed.
Yam states that the number one coolest thing about the Sig P320 is how truly modular it actually is. He took the stock pistol to the range and states he really liked how soft the gun shot. He also remarks at the tracking and recoil was nice as well. The stock version isn’t a bad pistol.
But he doesn’t leave it stock.
Here are the changes he makes throughout his reviews:
1. Trigger swap
2. Grip change up
3. Optic added
4. Slide swap
5. Another grip change up
6. Changed out optic
For the trigger, he wanted to upgrade to a GrayGuns trigger kit. The stock trigger wasn’t bad, but he wants a different feel for his pistol. He likes the GrayGuns kit because it’s a straight trigger and the only kit that included a sear. In the upgrade, he uses the trigger and sear but uses the stock springs as he wants a heavier trigger feel. He highly recommends the trigger kit and says it made a dramatic improvement in the system.
For the grip, Yam says that the stock grip needed to go, fast. The stock grip has magazine cutouts on the bottom to help in the removal of a stuck mag. What it also gives, according to him, is a bunch of right angles to get hung up on when trying to do a quick reload. He changes it up to a Wilson Combat grip module. It makes the grip feel narrower and more like a 1911 in the grip angle. Another nice thing about the grip is that it’s available in different colors and with or
without the manual safety option. As far as fast reloading, it has a gaping magazine well which Yam says is fabulous.
For the first review, he adds a DeltaPoint Pro optic, mainly because he has one already and it fits into the native cuts on the stock slide. Yam states that the optic is better than the plain iron sights. He reiterates that it was only on the pistol until something else showed up because he thinks the optic is too large and is overly cumbersome to adjust the brightness (as in you have to toggle all the way one way before it swaps and goes the other way).
Yam takes the altered pistol to the range and shot drills. He crushes his drills and has nice tracking. He says it was snappier than the compact in a similar setup, but that it still shoots soft. Overall, the platform is really nice and the upgrades he did only make it better.
For the second part of the series, he revisits the pistol after shooting, teaching, and concealed carrying it. He did make some modifications, as he knew he would and he is still very happy with it overall.
One of the next set of upgrades he did was to swap out the slide to a NORSSO EDC reptile slide. Yam likes the feel and looks of the compact slide. The other thing he added with the slide was a Parker Mountain Machine compensator. It’s a single port comp that has a semi-permanent install. He stated that after couple thousand rounds of shooting, it hasn’t come loose. The comp made it the pistol even softer to shoot and reduced the recoil giving a faster return with less muzzle movement.
The original optic he put on the P320 was too big, so he swapped that out for a Trijicon RMR optic. Not only that, but he put in some 10-8 Performance Sights that are Sig height and compatible with the slide. While he didn’t change the grip, he did texture the module for more traction. Word of caution from Yam is that the wall thickness is pretty thin so you have to be careful not to punch through.
In the end, he really likes the Sig P320 with all the mods. The trigger is still a bit light for his liking but it’s decent enough compared to the 2011 trigger he’s used to. He’s been carrying it daily, enjoys shooting it, and says it’s worth a look.
