I have a 44 mag, a 357, a 22lr, and a 45 acp in pistols. I recently bought a 9mm because the ammo is so cheap to shoot and practice. I have just read so many stories as to why the LEO's went to the 40sw and 10mm was developed because the LEO's wanted high capacity and the 9mms just weren't doing their job against drug addict perpertrators and cops were killed. I think the 9mm will be adequate but want the right ammo. My wife can't handle the other 3, only the 22, but she can handle my new 9mm with cheap fmjs.
