Curious about the durability of the Aluminum cylinder.

I know Smith has offered Al cylinders in the past without success.

Did they get it right this time?

I'd use the gun to practice and improve trigger control on light weight revolvers.

So I'll shoot it quite a bit and don't want to wear it out.

It shoots 22 LR right? The cylinder could be made of pot metal and would hold up. Nothing to worry about except the price people are asking for the 43C.

Well, since the .22 LR has a chamber pressure of 24,000 psi, substantially higher than the .38 Special at 17,000 psi, I don't think it's necessarily nothing to worry about. I know, S&W would not use the aluminum cylinder if they didn't think it was sufficient; then again, they do things like use scandium and aluminum frames, which supposedly are 100% up to the job -- and yet they have to put the cheesy little "blast shield" over the barrel-cylinder gap so the frame won't erode, which indicates to me that compromises are tolerated when ultra-light weight is the objective. While their lightweight revolvers are tough little beasts, they can't hold a candle to the all-steel versions when it comes to sheer durability.
