It is a sigma... cheap handgun.. horrid trigger pull. However, it is still a gun. I'd suggest something from the Springfield XDm series though personally. I have owned a sigma before.. and I now own a XDm. It's a world of difference and the price isn't too much higher for the XDm.
I'm actually looking to buy a Smith & Wesson 22A Series pistol. .22s are fun guns to shoot when you don't feel like blowing 50 cents every time you pull the trigger.
How do you like yours? Looking between a 5.5" and 7" inch barrel. Suggestions?
