Just been playing with mine and noticed the blue is certainly rubbing off in several places, including the plunger. Also, I measured the barrel to bush clearance by removing the bush and measuring the barrel dia with a vernier then measured the inner dia of the bush. .042" clearance seems a bit exsesive to me. Think i might have to think about an after market bush so what are you guys doing with yours?? Std or after market?? Tried resting it on a flat surface and holding two handed at 20yds with Geco pistol and got a 10 shot group in a 2" vertical row so plenty of room for improvement. Dont think a lot to the std sights either but will sort them once pistol accuracy is improved. Got to say im still lovin the gun though. Tim
