TM - Sig P226

Another tune up for a friend. He managed to crack off a bit of the stock piston. It was venting gas pretty heavily during shooting. Swapped it out for a PGC 1911 piston I had sitting around. Brought the efficiency back up and the kick became a bit heavier. I still prefer the Nine Ball Dyna Piston for the P226, but since I was doing this more as a favor.
