S&W 22A upper and slide...what is made of??

What kind of alloy is the upper and the slide of the S&W 22A is made of?? It does not feel like steel to me...

The inner barrel itsels does not seem to be a steel piece interted in the alloy outer shell...it looks like a single piece...so are barrels and chambers made of alloy possible in a low pressure 22 LR firearm??

The frame is Aluminum. Pretty sure the slide is Steel though.

But the black finishing on barrel/upper and slide seems "painted", typical of light alloy construction and not blued as typical of steel construction....

The slide is steel. It is painted black, probably because blueing it would raise costs. The 22a is a great gun at a low price

Totally agree...I got mine on sale for $199 at Cabela's. Very accurate, nice ergonomics and top notch reliability...
