Dear Clusterfrack, you obviously know more than me, and are a better shot than me. I'm simply speaking as a 65 year old arthritic retiree that comes here for knowledge. I shoot a lot more than most- yet I come have to the conclusion that I will never train out of shooting low and left with glocks. I hope to be able to roll out of bed in the middle of the night and hit center mass of a "bad hombre" in my home (longest sight plane is 30 feet). I also have a Colt M4 with a Meprolight. Every thing you say is absolutely wise; I'm simply realistic. If you were here in my home town I'd be delighted if you'd coach me. The OP has to figure out what will work for him at this place in his life. I'm, as I say, trying to be realistic and prepared as possible. You should know that I read everything you say and respect your wisdom!
