I've had hit or miss luck(and mostly miss) with the last 5 Springfields I've bought. I think Springfields QC needs a little work. If you are going to look at buying one, I would highly suggest you go somewhere that has multiple copies of what your looking for, and closely compare them side by side right there on the counter. You may be amazed at the differences between guns of the same serial number range.
If most of the other Loaded models work like mine did, I agree with the salesman, they are total crap. Mine would not reliably feed hardball out of the box and by the time I was done, was basically put back to a standard 1911. I at first re-tuned and then replaced the extractor, and then replaced the guide rod for a standard spring and plug. This helped a little, but the gun would still act up just about every mag. I also had to file the safety down to a reasonable profile, as it would tear up my hand, and I replaced the MSH for an arched one and the long trigger for a short one. The last three being personal preference, and not really any affect on function. The more I think about it, I dont know what I was thinking when I bought it.
I have two of the WWII 1911's, one isnt bad, the other, pretty much a dog.
My WWII Champion is a shooter, and has worked 100% out of the box. It was the last Springfield I bought, and will also most likely be my last period.
I've always had the best luck with 1911's with my Colts, or guns built to the original Colt/GI specs. I had a few early Springfields that were, and they worked fine. Once they strayed, the troubles seem to have increased. I like them loose, with a little rattle when you shake them. I have yet to have a stock Colt not work from the box and their triggers have all been real nice too.
The point for me is actually moot now anyways, after 30 some years of daily 1911 carry and use, I moved on to SIG's and have never looked back. I sold off all my non Colt's, except for the Champion, and those left really havent been shot to much since.
