They will wear out, they were the first lightweight 45 and the gun art for that was not quite there as far as longevity went.
On the other hand as stated, it was a shooter and uber reliable. Only problem I ever had with mine was when I failed to clean it for 10 years (shot little, threw in back pack or the truck and just never got around to it)
You might check Gun Runners web site up in Anchorage AK. I traded mine in on another gun a few weeks back. From the buffer I suspect it had less than 50 rounds through it and I maybe put another 100 through it myself.
I think it was a police carry gun and not shot.
I could not shoot the small iron sight and it was a great swap but its one I will miss.
