Two complaints with Dan Wesson 1911's.
1. Duty Finish - gets cloudy when you use Break Free CLP, and possibly other lube/cleaners. User error - owners manual tells you what products to use for cleaning and lubrication that won't affect the finish.
2. Galling on stainless steel models - there were lots of complaints about this. Perhaps legitimate, but man, I was convinced galling issues on stainless steel guns had been fixed back in the 1980's. It's possible every gun maker in the world got the memo on how to avoid galling, other than Dan Wesson, but it seems unlikely. I don't know. It's probably also user error.
My theory - lots of experienced gun owners on gun forums looking for their first 1911 get recommended Dan Wesson's as an excellent 1911 option. It is.
The problem, most of these folks only know polymer framed striker fired pistols. A Wilson, Nighthawk, Ed Brown, Les Baer, etc, would also be an excellent option, but these guys who pretty much only own and shoot $500 polymer framed striker fired guns just can't choke down the entry price of those 1911's. A Dan Wesson, at $1,500ish is a lot more palatable to these folks, so they make the move to a Dan Wesson.
Now they have their Dan Wesson and proceed to treat their new 1911 like they did their poly-gun. Hose it down with brake cleaner, use their "six drops of lube", use the $10 unbranded mags they picked up at the gun show, or on eBay. Now the Duty Finish gets cloudy and is not as pristine as it was when it came out of the box, the gun is severely under-lubed, and hangs up, and the cheap (probably made in China) mags don't feed reliably. While the Dan Wesson is not as expensive as the Wilson/Nighthawk/Brown/Baer, it is still three times more expensive than their other guns, and now they're really mad. "How could a $1,500 gun have X problem, when my $500 "whatever" pistol with a crummy looking factory finish can go through the dishwasher ten times and look just as crummy as it did when it came from the factory."
Open the owners manual, read it, follow the instructions, and I suspect most of the problems don't surface.
