I press check my nightstand gun every few days, I check my revolver also.
I like to stick to very basic stuff, but also train in different tactics and methods. It is kind of interesting training in some new tactics because the coordination is wacky then after a little training the muscle memory picks it up and you have more skills, if ever needed.
Many accts of gun fights I read basic things go wrong and situations turn into scrambling chaotic messes, it seems like a good idea to have training and muscle memory to deal with unknown stuff. Some accts I have seen people get altered senses(tunnel vision, distorted hearing, shock, etc) so you might not always know how many shots you have taken? If you have you guts blown out and shock do you really trust yourself playing with the slide?
you never know.
