Hey guys, I had a brand new Glock 35 gen 4 - I purchased it new 2 months ago, and have fired about 200 rounds through it. When I bought it, I had the gun store put the Trijicon tritium night sights on it. I'm coming to the end of my police academy, and next week we are shooting with our agency, and going over the firearms drills/qualifications. So I've been practicing drawing/holstering my weapon in my safariland 6360 duty holster which is the STX plastic. I've been trying to draw/holster without looking 5000 times to build muscle memory, so when I go to holster it, sometimes I'll smack the front sight on the tip of the holster as it's going in. I practiced probably a hundred times today, and when I was done I noticed my front sight is a little loose, and wobbles maybe a mm when I manipulate it, or even if I giggle my gun.... I can't bring it back to the gun store I bought it from, because I brought it 2500 miles away. I've removed the slide, and can see the hexagon nut/screw that holds the front sight on. I've read about using a pair of needle nose pliers to remove the nut, and putting some red or blue locktite (by the way, RED vs BLUE locktite??) on the thread, then tightening it back up. My question is - I've never installed/removed a front sight before. If I back out the nut/apply locktite on it, can I easily tighten it back up and have it be straight/accurate? or do you need a special tool to get the front sight straight? Thank you!!!
