Ok guys for ccw 9mm,40s&w.or 45acp which one and why.
9mm is going to be easier to conceal and generally give your more rounds to pump into someone. Some manufacturers don't offer a .40 in a small version, but some do. A .40 packs a bit more punch and is what I use for concealed carry; but I am shy a couple rounds from what I would have if I carried a 9mm. .45 will pretty much blow a big hole in whatever you shoot, but you don't get as many rounds.. and the gun itself is going to be larger and harder to conceal. For Winter time conceal a .45 would be okay in my book, but in the summer when you wear less clothes... I think it would be too bulky.
Questions to ask yourself.
1. How much money do you have to spend? With guns you get what you pay for.
2. Where would you carry it? Go handle what your wanting and see if it is comfortable.
3. See if a friend has what you want and go shoot it first and make sure it's a good fit for you.
4. Great guns in my book and experience.. Glock, Sig, & Springfield Armory
