I just got my second Glock, a G21. It does have the 3.5# connector and came with some adjustable sites. This will mainly be shot at the range, and carried in my truck for whenever/whatever it is needed for. What mods would you guys suggest? I have to do something to it, just can't leave it stock! I'm open to all ideas, but don't want to go too crazy with it. Come on, I know you guys gotta have some good ideas. My G27 will stay in the house, and for now will stay stock( for now anyway).
