MARSOC (Marine Spec Ops) now carry 1911s again. Kimber built theirs for a while and they held up pretty damn well with everything they were put through, but they're pricey. USMC is back to Colt for their 1911s. The MARSOC 1911s have awesome grips made of a material called G10 originally made by Simonich Armory. Those grips are designed not to slip when wet from sea water, sweat or blood. Kimber Warrior II is essentially a clone of that pistol. I've shot pretty much every 1911 out there and, for the price, Springfield Armory Operator has done just as well as any of the others and are much cheaper. Again, this pistol is another MARSOC clone and even entered military trials. Personally, my daily duty carry is a SIG P226, which is carried by our SEALs. I've put thousands of rounds through mine with ZERO failures. But, it's a 9mm, which some people say lacks stopping power. However, if you're hitting what you're aiming for, a .22LR will do the job. Just sayin'. Whatever you get, put night sights on it. Trijicon makes very good night sights. You don't need a laser. They look great on tv, but they also give away your position. And, every shooter I know who has a laser on their rifle or pistol is readjusting them all the time. They just don't hold their zero, regardless of the brand. My recommendation is to get a good, quality pistol and practice, practice, practice with it until it feels like part of you. If you carry concealed, UNLOAD (remove mag, check chamber!) and practice drawing from where you're going to conceal it and dry fire. When you're sick of it, do it some more. No point in carrying if you can't hit with it. Your life or the life of your family may depend on it.
Personally, I'm not a fan of tactical tupperwear, either, but H&K occasionally draws me in. That said, I know some badass shooters that can make a Glock sing. They're just not for me...
I was a USMC tactical firearms instructor and now do the same for law enforcement, so let me know if you have any questions. I'll be happy to help!
