Try as many as possible first!
An Armco Norinco wont set you back much more than a decent quality ruger .22 pistol. Sure it will be much more expensive to shoot, but a .22 just isn't the same. If you have any experience with guns, I wouldn't bother with a .22 pistol unless that's what floats your boat.
I would recommend you find a gun club, go to a range, try to meet people nearby that will let you try out as many different pistols as possible before you spend any money. The 1911's are great, but so are Glocks, Sigs, H&Ks, even revolvers are fun.
The best pistol for you will be the one that fits your hands well and that you enjoy shooting. It's not something you can easily describe by email but you'll know what you like when you feel it.
I have a revolver that I don't like to shoot. I have a double stack 1911 that I love but it's hard for me to get a consistent grip. I've shot single stacks that I really enjoy. I don't like the trigger pull of a glock and with the H&Ks I always pinch my palm when inserting a mag. Everyone's different, and some people are really passionate about a particular model, but hate another like you wouldn't believe.
Only buy a used gun from someone you trust. Read lots of reviews about different models. Stick with a quality name, or have a professional customize it for you. Try try try before you buy, then shoot shoot shoot till you run out of money!
