So, besides dry fire practice at home, I decided to invest in a BB gun "Glock Look-a-like". While Glock doesn't have an officially licensed bb gun version, Umarex has the SA177. Its very close, while it doesn't fit by SERPA, due to the safety on the side, it does offer me the ability to actually shoot in my backyard and to get the fundamentals down. I'll post a picture of it from my phone in a minute. It is a gas blowback BB gun at 380fps. Besides training it's a pretty fun backyard plinker as well. On a side note… could we have a "Training" sub forum?
