Well, yeah, duh, it puts wear on the gun! Would he suggest that you not drive your new car for the first 1,000 miles so you don't put wear on it? (Figger that one out!
)
The firing pin is a short little thing that is less likely to break than a lot of other parts in the J frame.
Most Smiths I've seen come through too dry. It may be some of the friction you feel would be reduced with good lube, which would also reduce the wear factor.
Realistically, you are really not going to _wear out_ one of the Al or Ti J frames -- it will wear you out first. I think what the CS rep is cautioning you about is sitting down to watch Lawrence of Arabia or something (what was that, about 15 hours long?
) and snapping the revolver 30x/minute for the entire movie. But even dry firing it, _you_ will wear out at some point! Be happy, don't worry -- it's a tool, not a keepsake. Oh, and by the way -- their CS is very good. If you do break it, they will fix it.
