![]() Accuracy seemed more dependent on individual bullet design than favoring a particular bullet weightĪnother factor I consider important is how a gun feels. This gun isn’t going to be limiting your ability to hit your targets at any PCC matches. Even the military ball ammunition consistently managed sub 3” groups. The lower price point Hornady American Gunner 115’s pulled a second-place finish at 1.38”. The smallest 5 shot group was a 1.24” delivered by Hornady 115 FTX Critical Defense ammunition. Top quality ammunition often brings the best accuracy The gun was shooting so well that I feared the red dot sight might be holding back the results so I mounted a Nightforce 2.5-10x scope and continued the testing. Accuracy testing was done at 50 yards off the bench supporting the gun on a couple Armageddon Gear range bags. I found the accuracy of the Sig PCC barrel/ action to be fantastic. The little Nightforce 2.5-10x may be overkill for the 9mm but it made group testing a breeze to find true accuracy The trigger weight averaged out at 4 lbs 13 ounces after 10 cycles on my Lyman Electronic Trigger Scale. It’s a robustly built trigger to stand up to the punishment that the rapid cycling PCC bolt dishes out while still providing a reasonable pull to allow fast accurate shooting. This isn’t one of Timney’s super light precision long range type triggers. The MPX PCC comes from the factory with a Timney single stage trigger.

The 9mm round only has a small amount of exhaust gas and pressure to work with compared to rifle rounds, but when competing at the highest levels every bit helps. The simple but effective design works well, keeping the muzzle steady allowing faster follow-up shots on target.
