I do use Loctite when replacing front sights. My choice is 262 but 242 works well too as long as you clean/degrease the screw with alcohol. I’ve never had to use heat or more than finger force to remove 262 and have never had one come loose.
The very short description of sight radius (distance between sights). If you have an imperfect sight picture when the round is fired - that error is amplified the shorter the sight radius. The further away the target being shot at is, the greater the effect.
Here’s a chart I just found that shows with a 3” sight radius and a .5 mm error in sight picture the effect is 3 inches at 25yds. But with a 6” radius the effect is only 1.4 inches.
Don’t get too consumed with this for the type of shooting you want to do - almost all pistol self defense shots are at extremely close ranges. It’s just something I keep in the back of my mind and really just consider for competition shooting.
There is a reason Glock created the 17L for competition and not long after new rules about the pistol length were created, effectively banning the 17L from competition! They had to shorten it down to the model 34 to be more fair.
