A SIMPLE KEY FOR GLOCK 30 GEN 4 UNVEILED

I set a Tarran Tactical package into a gen three g23 and it's now Tremendous lite but I nevertheless could not hit just about anything with it. My Mate could shoot it really well but I struggled. Lastly I altered the inventory sights to the Dawson Precision Fixed Levels of competition Sight Set and now I do pretty good with it.Maybe a dumb question
