Model 317 .22 LR, Metallurgy Strength

[RAMS]

It's wise to practice and plink a lot with the ammo one carries. Being made of aluminum, will the cylinder and frame of the 317 hold up to a diet of Stinger and/or Aguila Super Maximum (self defense/hunting) ammo without stretching sooner or later?

Wondering if any gunsmiths have heard about or had experience with this question.

My 317-1 was initially used as a loaner during instruction. The ammo was mostly Blazer and Federal Champion, which are high velocity rounds (not hyper). After about 6K round, the gun had severe endshake, to the point where the cylinder was contacting the back of the barrel. I shipped it back to S&W (on their dime) and they fixed it under the Lifetime Service Policy.

Can’t remember the round count but the same happened to mine and S&W fixed it per the life time policy . One more thing too was they refinished/coated it so it looked brand new !

After some research, it appears that the metals used in the frames and cylinders of the current model 317 could have changed. Given the Lifetime Service Policy, I very much doubt that the change would have been toward weaker metallurgy.
So, based on Iscoco's and your great experience, I'm going to assume that hyper ammo will not ruin my new 317's frame or cylinder. And if it does, there is always the S&W Service Policy.
