Stock sights on the Glock? I can deal with stock triggers, but I have to replace the sights, and I really dislike both three dot, but even that's better than Glocks weird rear sight.
I just sharpie over the stupid white 'cup' on the rear sight. The blacked out rear makes picking up the front nice and fast and it's a cheap fix. I touch it up every 1000rds or so.
I tend to pull the same way due to tightening of my fingers on my right hand as I pull the trigger. I basically have to grip the pistol as tight as possible to keep it from happening.
I can't remember the last time I shot handguns...semi-auto rifles are just too much fun!
When I took training the instructor said to get a feel for how hard you should hold the gun to do this: hold the gun loosely, then start tightening your grip until you start shaking. Then back off just enough for the sights to stop shaking.
