Well, I've done this dance for awhile. In the People's Republic of California, soon to be the next state of Mexico, we are not allowed to carry most of these guns, or any guns, in about half the state. So, criteria for concealed carry is it has to be DEEP carry, and, when that's the case, weight becomes as important as size.
I have three in this category:
First, Beretta 950 Short. Inadequate caliber, but it goes bang, quickly, it's accurate, and reliable, and, smallest by far of the bunch, we can get here, no Kel-tecs allowed. The Beretta being DA/SA, in SA mode, has an EXCELLENT trigger, and for a point and shoot, that REALLY helps you hit your target.
Second: Kimber Ultra Carry II. After about 300 bucks extra, this is a gun I can conceal in a couple places, but, it requires hefty straps, since at 25 or so ounces, it's noticeably heavier then my other carry guns. It is the most accurate, so far, will shoot limited amounts of .45 Super, thanks to my fantastic gunsmith, and, 230 grain ball all day long. It's got an excellent, maybe 3 pound trigger, as well.
Third is your snubby, the 360PD, S&W. At it's super light weight, 12 oz, .357 magnum is out of the question. Extreme pain comes to mind.
After shooting a .475 Linebaugh, with 400 grain bullets, at 1300 fps, I put a Corbon full house 125 grain @ 1400 fps down range out of the little gun.
OUCH! I put the gun down, emptied the cylinder, and went back to shooting .38's. With Corbon's Plus P 125 grain HP, or their DPX line, you get nearly magnum velocity out of a .38 snub nose, around 1150 fps, with a 2 inch, and, it's easy to shoot. I think these guns need bobbed hammers, maybe, we shall see, filled in, wood grips, to give you something to hold onto, and an action trigger job to smooth out, and lighten the DA pull.
That, finally, is my complaint on most of these DA guns. Trigger pull means accuracy, and you don't want to end up like the miracle guy in Pulp Fiction,
splattered on the wall because your DA trigger pull made you pull all your shots off target, missing the bad guys.
That's my two 'sense' on the subject. Finally, my ideal gun for concealed carry is either a Detonics CombatMaster, which comes close to your specs, as the most compact of .45s, but, it's heavy. If you can use a holster, or shoulder rig, it's great. Shoot it all day, super accurate, and will take HEAVY loads, thanks to all stainless construction, for years.
Second would be bigger, the S&W 1911 SC commander size. It weighs the same as some of the guns you list, will be FAR more reliable then any, and, have a fantastic trigger pull, with all quality parts.
That said, I commend you on your size comparision, and, only can comment that a weight chart might be the next step.
Thanks Bobo
