Most Helpful Positive Review Beautiful Compensator
Not compatible with the Faxon Firearms Sig Sauer P320 Full Size Barrel. Fits the profile of the slide perfectly. Killer Innovations doesn't make a barrel for the full-size P320 so I tried a different brand and it leaves a huge gap making compensator look like trash. Loosing the Factory look of the f...

Most Helpful Negative Review SUCKS, will not cycle
I have this specific P320 comp and it will NOT cycle the slide. I have tried time after time, round after round, heavier to lighter loads and NOTHING. I set up a slow motion camera to see what was going on and I can tell that the slide cycles ALMOST all the way but than the spring rod impacts hard a...

Love the barrel, Hate the compensator

by Indyrocker, from IN, United States Written on October 15, 2023
I purchased this product along with a Killer Innovations barrel for a P320 compact. The barrel is great. I noticed that my group sizes halved with respect to the factory barrel. When I initially added the compensator, I had several failures to fully extract and several stove pipe jams. When I adjusted the port adjustment nut out to it full extent (completely closing off the large, most aft port) the feed problems ceased but the copensator became loose with the second shot. After tightening to the point that I was afraid of stripping the threads, the compensator stayed on for three more shots before becoming loose. It also adds quite a bit to the length of the slide turning a compact into something just a bit longer than a full size. Not so useful for concealed carry. Love the barrel; the compensator, not so much.
Pros:
  • none that I can think of
Cons:
  • Quickly becomes loose. Adding it to a compact makes it not so compact
Best Used for:
  • Returning to sender
Would recommend: No

No front sight mount

by Sig12444, from KY, United States Written on September 25, 2023
In a world of compensated handguns one of the main things I look for is low recoil and faster follow up shots & in my experience the best thing about compensating a hand gun is win it offers both of those options and when you can just buy a sig specter comp from sig that allows you to have best of both worlds any other comp system isn’t up to par .
Pros:
  • Ehh
Cons:
  • No mounted front sight
Best Used for:
  • Not up to par
Would recommend: No

What's the Big Deal?

by Jake De Muss, Verified Owner from New Zealand Written on May 11, 2023
You buy the Killer Innovations Sig P320 Compensator, take it o the range to test, get a stove pipe/FTF, and then you buy the Armory Craft Recoil Tuning Kit. I ended up using the 11 lbs. recoil spring with this comp. What's the Big Deal?
Pros:
  • Great Price with Bonus Bucks & Coupopn
Cons:
  • Finding a Holster Might be a Problem
Best Used for:
  • Cool factor
  • Recoil mitigation
Would recommend: Yes

Issues and questions

by Joe, from KS, United States Written on August 4, 2022
Fit just fine on p320 it was on. But shooting is something else you have to manually pull the slide back to have another round enter the chamber to shoot again. So I tried with one of my p320C's fits doesn't work and no instructions on how to adjust it. I have there barrels on them as well. So.
Pros:
  • None
Cons:
  • money & useless
Best Used for:
  • trash can or paperweight
Would recommend: No

Won’t cycle

by Roberto, from LA, United States Written on March 25, 2022
It looks great, but I can’t get it to cycle. Tried lots of ammo types. Watched a video about their Glock version and they say lower the spring weight and use flat springs…. I may try to lower the weight, but I’ve not been able to find a flat spring for a p320.
Pros:
  • Looks great
Cons:
  • Too picky
Would recommend: No
