For the last 8 or 9 months my go-to carry gun has been my 642, so I guess that qualifies. I bought it in January and have put just over 1,100 rounds through it so far, with probably 3 or 4 times that many dry-fire "rounds" during practice drills (drawing, reloading, one-hand manipulations, etc.). I had a relatively minor issue that was fixed by replacing the ejector rod and it has had no issues since then.
I took this picture earlier tonight. You can see the finish wear under the cylinder latch, along the trigger guard, and at the forward edge of the frame.
This is a rather poor picture of the backstrap I took back in August before I figured how to use the "Macro" function (have I mentioned I'm not a camera guy?).
And this is a picture of the same backstrap taken earlier tonight.
This is the gun in my Wraith IWB holster by Seth's Gun Leather. It's a great combo.
It functions well, shoots great, and is easy to carry. As for the finish issues, I'll probably get it refinished at some point in the future but it's not a priority right now. It works great as is.
And for those interested, I carry it loaded with Speer 135gr Short-Barrel GDHP +P.
