AMT Hardballer question

[Ignacio49]

The stainless steel used to manufacture the AMT Hardballer - was it a soft ss? a hard ss?

What were the cons/pros of using a soft metal, or a hard metal?

Thanks

I have a Hardballer but don't know the type of stainless steel they used. I do know that it is the most accurate .45 out of the 4 I have. Two of the 4 are Colts.

I don't know if it's the same steel, but I had a stainless AMT DAO .380 I carried for a while... the slide cracked under the ejection port. I didn't think much of that, and when I got it back from AMT, it disappeared.

The problem with AMT 1911s was whether the steel was hard or soft. It was an issue with galling

Harry Sanford was partial to 17-4PH stainless for the AMT pistols. I have several AMT pistols, and had never had any galling problems with modern gun lubes.

My friend's Hardballer s/n is A31xxx, Irwindale, CA. Any idea about its quality and/or vintage?
