I stopped thinking about it and decided to get one a NIB glock 17 bone stock w/ 3 17 round mags, 470 w/ military discount. Im psyched to have it and looking at ammo prices it will supplement me practicing with it and my 21sf which is my carry. I bought this as my range/plinking gun but plan t make some additions to it nothing to big just a set of sights, maybe a mag well and extended slide release. But I would really like a dr optic or something comparable and a extended magazine release. I saw a 17L with these and it was impressive. but If I dont add most of these things, Im still good with just extended slide release and some good sights in case I get to carrying it , with that said who makes the best self defense ammo if I should chose to carry it, and where to get ammo buy the case to feed this thing and any modifications that you all suggest to my new addition would be great thanks.
