I have had 2 S&W's a Bodyguard, and a Centenial, both Airweight for over 35 years.
They both have been carried and shot a lot, including some hot reloads, as well as some +P+ factory loads.
They have both been work guns, and I have also killed a bunch of rabbits with them.
They still work fine, but now I do not shoot them much as I want them to last me till my end of days...
However S&W seems to now be having a BUNCH of problems with the current genetration of light weight alloy framed guns.
I have a 325 Night Guard, and I have shot it a couple of hundred times so far. I do like it.
I have some more ammo I am going to test in it, then I plan to shoot it "not so much"...
The new "airweights" just do not seem as rugged as the older ones to me.
