What steel to use to make a pistol extractor?
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.0 -

I would use 1095 or O-1 heat treated to spring temper. 59-60 RC is too hard. 0 -

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.0 -

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.0 -

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Notice where it says this listing is no longer active?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.0 -
Last one I made,I used a Sawzall blade. 0
