All stainless steel handguns, are quite the marvel – well, at least they used to be. I still remember the very first stainless steel handgun I ever saw, it was the Smith & Wesson Model 60, a little 5-shot snubby revolver – it sold like crazy. However, when it came to semi-auto pistols, there were some serious issues with a stainless steel frame and slide – if the two parts were made from the same formulation of stainless steel, it would “gall” – after a few shots if the gun wasn’t heavily lubed, the two same stainless steels would mesh together in such a way, that the gun would jam – the same stainless steels – would rub against one another, causing friction in short order, and the slide wouldn’t move back and forth on the frame. Not a good thing.
I owned a then Safari Arms sub-compact 1911 – and it was quite the work of art back in 1980, and it was a great carry piece. I now wish that I had kept it – if for no other reason than nostalgia. However, the frame and slide were made out of the same stainless steel and if the gun wasn’t kept heavily lubed, the slide would stop moving back and forth on the stainless steel frame. It didn’t take gun makers long to figure this out – I don’t know why they didn’t realize this problem, before guns were shipped – surely, they tested those firearms. Now, when you see a stainless steel semi-auto with a slide and frame that are made out of stainless steel, it is slightly different types of stainless that they are using – and it solved the problem of galling.
Some of our long-time readers have requested, once again, that I do more articles on all-steel firearms, especially semi-autos. We try to not let our readers down, and if I have firearms in my meager collection, that qualifies for an article, I’ll sure do some testing on it. Today, we are looking at the S&W Model 4006 – and it was quite the handgun when it first came out in 1990, chambered in the then fairly-new .40 S&W caliber – it was all the rage, back then!Continue reading“S&W Model 4006, by Pat Cascio”
