Can't drift rear sight on SR40C
I just picked up a nice new Ruger SR40C. It shoot like a dream. Nice tight groups at 21 feet, but just about 2 inches left. I loosened the set screw with a 5/64 allen wrench per the instructions, but I can't drift the darn sight to the right. I've been banging on it pretty hard with a plactic bullet puller (which is made of really hard plactic), but it just won't move. I haven't tried putting it in a vise yet as I didn't wanna damage anything. Is a brass punch really necessary. Any suggestions?
Just found a couple of posts on various gun forums that suggested putting the slide in the freezer overnight. I'll try that tomorrow night, unless someone here thinks that's a bad idea.
One other thing, does anyone make fully (and easily) adjustable sights for this gun (not night sights). I like to experiment with my hand loads and need to easily be able to adjust the rear sight.
