A full house 10mm in a Lightweight Commander would rather snappy to practice with, something I have to consider after 40 years of having to deal with a tendency to flinch. It's why I actually prefer the 40 S&W over t he 10mm and anyone who considers the 40 "short and weak" should try the Speer High Energy 165 grain Gold Dot. A 165 grain bullet cruising along at 1150 fps. is NOT "short and weak", it actually produces as much energy as most commercial 357 Magnums. BTW, I load my own practice load to the same specs. using Longshot and a 165 grain Extreme heavy plate HP and it sounds remarkably similar to the 158 grain American Eagle JSP 357 Magnum.
I am NOT a fan of bushingless 1911's. Yeah, I know it's fewer parts. It also means that you now have a wear point that is a rather expensive slide instead of a cheap bushing you can purchase from Brownell's every day of the year. In addition field stripping one of these pistols goes from dead simple to about as difficult as field stripping an old S&W model 59.
Sum it up and what I would like to see from Ruger is a 40 S&W Lightweight Commander, that would be one I would just have to add to my collection. BTW, currently have 4 SR1911's, 2 stainless GVT 45 ACp, one Stainless CMD 45 ACP, and one 9mm Lightweight CMD. For the money I feel that Ruger has it just right and the 45 calliber CMD is so darned accurate that I sort of suspect I got a hand tuned version intended for some magazine reviewer.
But they have some "experts" with some very opinionated opinions regarding 1911's.
