About two weeks ago I put TFOs on my XD and my GLOCK. When I installed them they went on fairly loose (no sight pusher needed).
The sights are great recommend them highly but somewhere between my last shots fired yesterday and cleaning them today the rear sight on the GLOCK fell off and the XDs set screw was 1/2 a turn loose this was after about 1000 rounds in each gun Re-Tighten every 300 to 500 rounds or you will be out $90 like me
P:S it was not a sign to sell my GLOCK
