Socrates, if a nice trigger is high on your priority list, it is hard to beat a 1911.
Exactly. You mean like this, with about 90% Ed Brown parts, tuned by Jack Huntington for 45 Super?
mattro, I'm glad you brought that up, so I could go through it.

Here was my brief try at a snubby 45
The Kimber Ultra Carry II I got was a good one. Had Jack set it up to shoot 45 Super, stiff springs, and sold it to a forum member here for a song for what I had in it.
Here's my take on the 1911, and why I think Glocks are the way to go.
First, 45 ACP REALLY likes a 4, or 4.25" barrel, so, you are after either a Commander sized gun, or, better for CCW, a CCO. The CCO's are scarce, and expensive. If you get an alloy frame, it better run right off, because if you ramp the gun, it takes away the outside of the alloy, the hardest part, and, eventually, if you shoot the gun a lot, you end up
having to put an insert in the gun for the feedramp. Orion is doing this to the gun I sold him.
S&W has yet to make a Scandium CCO sized 1911, but, they have external extractors, not my favorite.
Now, the reason for selling the Ultra Carry is although it was 100% reliable, if you put it next to a commander, or full sized gun, you can see the difference in tolerances. There just isn't as much room for things to happen, and, the timing, and springs have to be changed more often, and, well, just think of it like a Ferrari. When they are tuned and tight, nothing like em. But, they are much more likely, due to the high tuning, to go out of tune then a Detroit car. Essence is, if you have a small block chevy or Ford producing 1 horsepower per cubic inch, it's tuned to tight tolerances, and, it is more likely to break down. If it's producing .5 horsepower for each cubic inch, it will run forever, all else equal. Same with the UC sized guns. Springs die faster, and, you just don't have as much room for error in feeding as the full-sized guns.
Also, the beavertail, which I don't need, keeps sticking me in the stomach, the way I carry it. And, you can't replace all the MIM parts with forged Ed Brown or Wilson stuff, because the Commander is about the smallest size that they make that stuff for.
Yes, it was a nice, powerful, light package, but, for the above reasons, not what I want to bet my life on.
So, I'm after a 4" barrel, 45 caliber, or at least 40,
good trigger, and, the gun has to be light. I could go with a
stainless Detonics Combat Master VI, but it also lacks a grip safety, and, it's heavy in thunderwear. Doesn't have a beavertail, which is good.
Now, the problem is, the gun you are looking for is fairly rare, CCO size, and the prices are pretty steep. I've almost picked up an alloy commander from Kimber, and, another stainless model, but, when push comes to shove, they aren't much different in size, for the way I carry, from my full sized gun.
Why bother?
It really needs to be a CCO, and, they don't grow on trees.
Now, the Glocks are blocky, and a bit thick, but, I have big hands, and, they are lighter, and smaller then the 1911's. Yes, the trigger sucks. But, the barrels on the 30/29 at 3.78 give you ballistics with jacketed bullets equal to a 4-4.25" in a CCO. they are cheap, and, if I ever have to use the gun, since my police chief hasn't issued a CCW in 30 years, it's going into an evidence locker for a long time.
Also, the 26 gives you near 357 type numbers with 9mm, i.e. with 125 grain bullets, consistent 1200 fps, and, that only weighs 20 oz.
At combat ranges, the trigger isn't as much of an issue.
The only reason I haven't bought a Glock is I have my little
357 360PD, and, with a bigger grip, it weighs 10 oz less then even the loaded 26, even though it's only 5 rounds, instead of 10. It gives similar ballistics to the 26, but with heavier bullets, in .357.
So, the bottomline is, the 1911 that would be what I'm after is expensive, relatively rare, and, if used, would be gone. Glocks, 29/30, carry more rounds, 10, max in Kali,
are built like brick houses, and, with a 30 dollar spring kit, will shoot 45 Super, and, a barrel change might also be a good idea, but not a necessity.
Another, slightly nagging alternative is a S&W airweight,
Maybe a 60, 24 oz, but the longer barrel would be great, and, I could use a speedloader(s) the same for both guns.
Or, get a used 38 Plus P for around 300-400, and have two guns, 5 rounds in each gun, still cheaper then buying a new Glock. Plus, with the longer grip, the scandium gun 360PD
is just a hair too long for pocket carry. The grip sticks out, and, you could be made.
With a 38 special, you can shoot it with those little boot grips that come on the gun, and still control it.
Meanwhile, I'm trying to move, so spending is on hold...
