The first 1911 I owned was a 100% Stainless Colt Delta Elite in 10mm.
It was, without a doubt, the finest "factory" handgun I have ever owned. And after a light "fluff and buff" by a local smith in NoVa, it was astoundingly reliable, accurate, and easy to shoot--had less recoil than a .45acp 1911. When it was complete, it had a polished ramp, lowered ejection port, a Videki trigger, tuned lockwork, a Wilson "Dwyer Group-Gripper" full-length guide rod, and a set of custom rosewood checkered grips with Colt Delta medallions.
It would feed ANYTHING, was match-grade accurate, and went BANG every time you pushed the bang-switch. In the 5+ years I had it, it never once jammed or had a FTF or FTE. From the cheapest range-supplied reloads to the most exotic defensive rounds (MagSafes, HydraShoks, Custom-loaded SilverTips, bulk "YellowBox" FMJs--it just always went bang every time, and on-target.
In short, it looked fantastic, performed flawlessly, and I trusted it as my primary self-defense tool. And it got a LOT of "gee whiz" comments on the ranges, which was nice.
All that said, I can honestly say I never had it kayaking or white-water rafting, so I can't speak to it's performance in such conditions, but I have shot it in the rain, in below-freezing conditions, and in the hottest, most humid NoVa summers you can imagine, and it just always went bang. I can't see a little water affecting it negatively, but I've never done that, so I can't speak to it with any objective authority.
Box-stock, it was a fine firearm. With a little TLC from a good smith, it was a treasure.
I'm still kicking myself for selling it.
When I finish grad school, replacing it will be one of the first "big ticket" firearms purchases I make!
