Ive owned right around 40 1911's over the years, and of a number of different makes. The only ones Ive ever trusted to carry or bet my life on were original Colt and USGI guns, that had the necessary "reliability packages" done to them to make sure they would function with any ammo I put in them, and put some better sights on them.
The majority of the clones always had troubles of some sort, and that includes Kimber and Springfield. Pretty much all of them needed additional help and fiddling to try and get them to work properly.
Even then, many didnt. My first Springfield Loaded wouldnt even function with GI ball out of the box. My Kimber Ultra Carry, rarely made it through a mag without a stoppage.
I like a good, working 1911 as much as the next guy. Finding one that does that, right out of the box, and doesnt need some sort of fiddling, hasnt seemed to have changed much that Ive seen over the years.
This past year, after a self-imposed hiatus on buying 1911's for the past almost 20 years, I broke down and picked up a couple.
One, was a new Springfield Defender. While it was so tight, you couldnt take it apart by hand, it seemed to run OK at first. But now that its loosening up a bit, its starting to choke on things that the other 1911's I have, have no troubles with.
I also picked up a basic High Standard that was used, and seemed to be OK as well at first blush. Until I got it home and actually tried to take it apart and shooting it. The slide was not machined correctly, and the slide stop had issues. Took some fiddling and a new slide stop to get it to run, and so far, it seems to be doing OK, but here I am again, fiddling and farting around with something that I shouldn't have to, and the main reason I got out of them back at the turn of the century.
In that time since, Ive bought around 45 SIG's and Glocks, and all of them, except one of the SIG's, worked 99.9% out of the box, with no other fiddling.
That one SIG that was trouble? It was a P238, yet another, 1911 clone, that had problems right from the start, NIB.
Color me jaded, but youre going to have to go a long way to prove to me, that everyone and their brother making 1911's, made them "better".
People can, and already have tried to make Glock copies, and already from some Ive seen and one Ive owned, a CZ P10C, they are headed down that 1911 road.
