I don't and haven't owned a 25 ACP pistol, though I do have an RCBS 25 ACP die set and (I think) a shell holder for the caliber in the die box. The sizer die makes a handy neck sizer for my 25/20 WCF brass. There are a couple 32 ACP pistols in the safe.
I inherited a Colt 25 ACP from my dad. I remember seeing it when I was a kid. I wish I knew the back story on it because it dates back to the 1930's. I have no idea how dad ended up with it. I had forgotten all about it when my mother gave me all his guns.
I wanted to rework a 22 mag platform in the worst way for a 25 ACP . The primer would have been the most expensive part even in bismuth bullets . Of course weighing those tiny little powder charges .
