mdog, I know you live in my area, so who would you recommend if I wanted to get a set of TFO's installed on the 21 that is fairly local to us?
There's nothing in LaGrange. Newnan would be your best bet.
Personally I prefer Glock factory night sights. They will install them for $60.99 tax included and have a 15 year warranty. No fiber option though. If your gun is used it wouldn't hurt to stop off in Smyrna and get a free "update and inspect" anyway. Then if you want you can get the free extended slide stop and/or mag release put in while they are looking at it. Not to mention grabbing a cool Glock Pen for all your sale thread pictures.
