I'll admit, I'm kind of shallow in that regards. I saw the boxy style that separates it from other pistols and like that uniqueness. The barrel of most pistols are similar to the one your wife is using and I admired the unique design. :D

Your best bet is to join a club and talk to the range master. The other shooters will be more than happy to let you fire their toys. Keep in mind, most of us have strong preferences as to why they like their gun best. And that's terrific.
