You really, really need to shoot some of the pistols you've named, and those others have named in this thread, and decide for yourself. You're seeing firsthand how people's opinions and experiences can easily vary.
My 2 cents ...
If we're restricting this to just Pistols ...
Got my first Lightweight Commander about 71-74. Worried about the aluminum frame. Couldn't wear it out, but worried about it anyway, so I traded it for a steel Combat Commander. Still got it ...
Went through bigger & littler Colts ... still got some ... Sometimes it's like owning a British car or a Harley, though, because most Colts & clones generally seem to require a little more interest and owner/shooter involvement in their upkeep and maintenance. I've still got some replacement parts out at the bench I'm going to install on one of them ... when I get around to it. I do have to admit, though, that when one is set up "just right" by a smith that knows the business, there aren't many more no-nonsense, straight shooting, easy handling pistols available for serious shooting.
Got a Ruger P-90. Ugly, big, blocky ... reliable as the atomic clock ... still got it ...
Turned down a $200+ bargain on some import called a BDA in .45. Wish I'd gotten it ... Not because I think they're that great, but it was a turning point for European design with the US market in mind. Shot some good later SIG's, and some so-so ones ... never again felt the urge to get one ...
Liked a HK P9S .45 I carried on loan for a while. Accurate. Period. Ahead of its time with polymer composite frame. Didn't like it enough to buy it, though ...
Had a Star PD. Carried it a lot. Always worked. Suspect the aluminum frame wasn't as good as the early Colts. I was lucky, I guess. Wish I still had it ...
Shot a lot of Glocks. Still do, from time to time, at work. Don't care for the grip girth, grip angle, trigger or magazines.
Got a couple S&W .45's. 4513TSW & a CS45. Great little pistols. More accurate than I care to think about. Reliable as my Ruger. May find something they won't feed and fire someday ... then again, the way they've always functioned, maybe not ...
Going to get one of the SW99 .45's when they're certified and released a little later this fall ...
How can I recommend a specific .45 to you, when I can't seem to settle on any one, or two, myself? :roll:
