I’ve been quite satisfied with the 9mm. It’s been 100% reliable with any brand of brass ammo. I don’t run steel through my handguns.
Weight, feel and concealability are good. With quality self defense ammo a 9mm has plenty of stopping power. And it’s nice when your carry guns use the same caliber.
It’s really nice when your long gun and handgun use the same ammo.I bought my wife a CX4 in 9mm to use with her 92fs.Both guns use the same mags,it’s very handy.
