I just ordered my first Glock. It's in and waiting to be picked up. I decided on a Gen 4 G21 to start my collection. I'm excited to get it and see how it shoots. I think I'm going to install some green Meprolight Tru-Dot Night Sights. But I'm not sure. I'll be perusing the Forum for your experienced suggestions before I pull the trigger on which sights to get.
