For the last 2 matches i have noticed the slide cycling oddly like something is hanging up or slowing it down. It only happens a couple times per stage, and have not had a chance to reproduce the problem in practice yet. Nothing in the gun looks like there is unusual markings or wear on any of the parts. It is a stock 2 with 1 piece sear, titan hammer, bolo, ex.firing pin block, henning guide rod, 8lb. Recoil spring, and the barrel is reamed. I can definitely say it is not a ammo problem.
