Three of my glocks all my 45's 36,30 and 41 all have Tijicon HD'S on them, I shot my 36 the other day at the end of the day I was wiping it down and realized my front sight was loose.When Smith put the sights on he didn't put any loctite on them. I called him today and he loctited and snugged it up for me. I also took my 30 and had him do the same. He said it felt tight and didn't want to take it off but I said let's do it to be on the safe side So he did and had a hard time getting that screw threaded back in but he got it I don't see any loctite that ozed out but the 36 he really put a healthy amount that is visable . Any ways is it the norm to loctite the front sight screw or not? Thanks, just curious hate to have it work loose he said he doesn't normally loctite or have any issues.
