What steel to use to make a pistol extractor?

Post by Quick&Dead » Sat Mar 09, 2019 9:26 am

Thinking about making a obsolete pistol extractor that is no longer available.

What would be the best metal to use?

I'm thinking A2 tool steel with a hardness of RC 58-60 should work.

IMHO, the physical dimensions of the extractor, cartridge, chamber would be the most important factors. A lot of 22's I've worked on. Didn't even need extractors. Residual gas, blew the empty cases out of the chamber. On the other hand. Hot ammo in a rough chamber. Would break the extractor, if it was hardened to much.

Specially if the extractor, has a small cross section in the "hook" area. Wouldn't be heat treating it at all.

I would use 1095 or O-1 heat treated to spring temper. 59-60 RC is too hard.

+1

I always selected the steel according to the job it needed to do.
IE>> If it had to "bend" or "flex" on every cycle, then a different type was used than if the piece
needed to be "hardfaced" to not wear out. A hammer head treated to be too brittle is just a handgranade waiting to explode. A drill bit too soft is just a waste of a drill motor's rotations.

4140 in the about the 45RC after machining. Looks like flat stock will work nicely.

added Not the first time 'GunParts' is wrong. I think the quality you are looking for in steel is "toughness" that can surface harden to resist wear.

That item is not only 'out of stock' it is also incorrect. The extractor for the P-30 is NOT shaped as shown.

I have the machinist drawing with dimensions for the extractor and it's not like gunparts shows nor does it interchange with the P-12, the extractor shown.

my rule has always been softer metal won't harm harder metals but a harder metal can certainly damage softer metals, that's how I start to make my own parts.

forgot to mention, did you try calling the number in this listing ?

I saw that a few years ago.

Notice where it says this listing is no longer active? Didn't try to call.
