Hi Marvin

I agree completely that stainlees automatic pistols are junk, but that is just because its to expensive to use proper materials.

When you say carbon steel is best, do you really mean carbon steel? 4140 wish is since maybe 40 years back one of the most used steels is not a carbon steel. It's an alloy steel and that is pretty different from a carbon steel.

I can't see any reasons to use carbon steels at all.

That belongs to the past.

During my 8 years as a toolmaker in Sweden and Austria (worked for Voere for a short period) I have never come across any imporositys in steel, NEVER.

During my 5 years as a full time gunsmith I have come across imporositys more times than I can count to.

And in all cases its in American steels, mostly invesmentcast **** but also quite a lot in forgings.

The forging is probably a good method when its used correct but in order to be as cost effective as possible much ****forgings are produced.

Problems with forgings is probably when the material is forged to cold and this way both imporositys and CRACKS can accour.

Firearms that have been problematic to me when it comes to cracks and imporositys is

Ruger, Caspian, Les Baer, Ed Brown, Para ordonance to meantion some.

Investment casting is only suitable when the quality not is very important, I prefer barstock and rarely see any problems whatsoever with it.

The majority of tools and machinery produced is made from barstock and that is probably because of the high quality.
