Hi. I learned of this site from a friend. I am looking for recommendations on a high quality stainless steel .45 caliber semi-auto handgun. I've never owned a semi-auto; only a stainless steel .357 Ruger SP101. Since I've never owned one and don't know much about them, please consider my ignorance if you care to enlighten me on what you think a good choice would be! I've read some other posts on the handgun threads and must confess they are over my head. I live in western Montana and would like something with a little more stopping power and rate of fire should I have an unfortunate run-in with an aggressive grizzly. I also prefer a larger magazine. Thanks in advance for any advice you care to share.
