I have to agree with AustinTX.
I'm a Colt fan. Beautiful guns, esp. in blue, and classic.
But, parts, fit, finish and accuracy? I'd have to say Dan Wesson, at least from the recent models I've handled.
Colt Gold Cup trophy with a God-awful trigger. Colt lightweight Government with a so-so trigger and so-so finish. Colt CCG with a thumb safety from hell. A nice 01991 Commander in stainless with the new beavertail (finally!) and a long trigger with a looong takeup. ONE blued Series 70 I handled at Cabela's two weeks ago had a nice trigger. But, the 70 Series sights don't do it for me. Even the Colt Custom Shop guns -- the special combat governments -- I have found to have so-so triggers, and no frontstrap checkering, even at $2,000+ !! This is all handling at LGS, mind you -- not shooting.
Contrast that with the DW Heritage at the LGS whose slide rolls on ball bearings, has a dovetailed front nightsight and a solid trigger that broke like a proverbial glass rod -- and you can still adjust that trigger for overtravel. All for under $1200. The V-Bobs I've handled have been things of beauty, too - dense, sculpted steel with form following function, tight tolerances, quality parts and smooth operation of all controls. Very high prices, though.
I have a Colt WWI repro in carbonia blue that is a thing of beauty to behold. Tiny sights, tiny thumb safety, still a joy to shoot. Wouldn't carry it for SD or for target shooting. I'd get a Dan Wesson for that. So, I vote Dan Wesson.
