A shorter list would be the ones that have had a malfunction of some sort. I have been fortunate that *nearly all* of my pistols have worked very well.
I think a lot of that depends on what you are focused on and the number.
I switched to SIG's and Glocks because the 1911s, especially the "clones" (Springfield's being the worst), had become very problematical and couldnt give me the "out of the box" reliability I was looking for.
Over the years, I owned right around 40 1911's, 17 SIG's, and 17 Glocks. All a mix of new and used, but most of each were new.
Of the 1911's, and being generous in the remembering, maybe 15 out of the 40 worked 100% out of the box (and that was using "ball" ammo). Most of those were the Colts, GI guns, with a couple of very early Springfields that were built to the original specs.
Of all the SIG's and Glocks, only one Glock, an early Gen 1 17, had a problem, and that wasnt a failure out of the box.
Everything else, load the mags and shoot, shoot, shoot.
Lets Say it's a gun or guns that have been reliable, that serves its intended purpose well, and that hasn't been repaired or modified since you got it, get it?
Id also include "break-ins" in that. I never got why I had to break something in on my dime, especially when I just spent a good bit of money on a supposedly "quality" gun.
