The first 10mm that I owned was a Smith & Wesson 1006 in the early '90s. It was a very accurate and reliable gun, but I definitely disliked the double-action trigger. I wouldn't have the trigger "fixed" due to liability concerns, so I sold it. My next, and last, 10mm was a Colt Delta Elite which I purchased up a couple of years later. It's here to stay.
As to the power of the 10mm, I can say that I remain unconvinced of its parity with or similarity to the .41 Magnum, but I do think it's an excellent cartridge.
