i wanted to make this thread so other people could offer their tips.
When I get any pistol, the first thing I do is either remove, or file off the rear site. You dont need it, and it's much faster. Rear sites are what cause people not to really aim in a high stress situation.
Something else, is learn to shoot with both eyes open. after you remove the rear site, it's much easier, but closing one eye cuts off your peripheral vision, and the eye you keep open gets tired, and strained. Try having your left eye squinted at first, and then just get used to it more and more. I've gotten really good with shooting pistols since I started doing both of these things. and dry firing helps ALOT. Just pointing at things around your house, and pretending to shoot.
