I have PA's advanced micro dot on my rifle and have absolutely no complaints. I've had it for maybe a year now and have put probably 1500 rounds through it(bought it used so I don't really know how old it is or how much it was used before) and haven't had any issues. I haven't torture tested it...
Not that I'm a super skinny guy, but I'm hardly big either. I've been carrying a Glock 19 IWB for like 2 years now, and the majority of the time I've carried it in a hybrid holster at around the 4o'clock position, which I've found to be pretty comfortable and super concealable. I use a Vedder...
