Before I shot it I installed a double diamond 3.5lb connector and ameriglo night sights. Stock barrel was dead on with good grouping. The wolf threaded barrel shot a little high. With the compensator it shot high and left about 5 inches. This was all done at 50ft with 180 grain fmj rounds. I'm not sure why the trajectory is so differnt with the wolf barrel??? Thinking of getting an adjustable rear sight to dial it in.
The recoil is alot more than I thought it would be. The compensator did a great job at keeping the muzzle down though. I can put alot of rounds through my kimber custom II .45 comfortably, but after about 30mrounds through the G20 I was done.
