Lyman M die

Can anyone tell me what size expander plug the 9mm has? My CZ75B likes a 358 cast bullet. Thanks Ron.

My particular M die says 358 right on it!! so the final expansion portion very mouth of case is just a Tad Larger..
Not near it to measure... later I will
OK the M die for Rifles is Marked 35R...Not 358... My Bad Memory... the Handgun oner is marked 38P and may be quite old..
For some reason I cannot put my hands on the 35R one... Kids prolly...
the 38P one measures .355 on long portion and .360 at the last stepped portion.. and I use it on my 35Remington as well.. Hope I did Not cause you any confusion..

There is one named 38 AP for 9 and 380 do not use the 38P. That was my mistake

I am pretty sure the larger boolet will still use the 38AP. My problem was a bulge with 380 and I think the 9 also with the, possibly larger, 38 expander. Hope I am not too far off
