Just seeing what everyone does for mods. For me, I do night sights, a grip plug, 4.5lb Glock connector (except work guns), extended slide stop (Glock) and extended mag release (Glock part, only on my gen4 17). I also put smooth triggers on my compact guns and a gen3 trigger on my gen4. I am going to do one extended mag for my G17, and I need a 9 rounder for my G30SF. Also- anyone run the Magpul 21 rounders?
