I'm looking at the 320 in .45
You'll look harder for a holster that fits it.
Got one about 6 months ago in 45. OK gun, like it enough to not want to part with it, but the slide is slightly taller and wider on the 45 than the other calibers....so finding a holster that really fits is something of a challenge. I wound up with a Garrett.
Just a heads up.
