ok i got this glock about thanksgiving time and i think it was an leo trade in i have put a thousand rounds through it with no problems but yesterday when i got back from the range and was cleaning it i noticed that the front sight is loose and i think its time for new sights. So should i send it back to glock or should i just take it to a gunsmith. I was thinking sending it back to glock to have them go over it. Also what sites do you guys recomend.
