TOP GUIDELINES OF GLOCK 30 GEN 4

I set a Tarran Tactical package into a gen 3 g23 and It is really now Tremendous lite but I nonetheless couldn't hit anything with it. My Buddy could shoot it really well but I struggled. Ultimately I modified the inventory sights to a Dawson Precision Set Levels of competition Sight Set and now I do pretty good with it.Most likely a dumb concern,
