New caliber to convert .32 acp pistols to restricted

[Jericho]

I have no idea where this nonsense about how "you can't do blowback with bottle-necked cartridges" comes from. What about 6 million plus PPSh41 and PPS43 guns (?) or, for that matter, that brand new A17 Savage sitting on the rack in my neighborhood gun store? Geeze!

I think it is a question as to if these pistols that were designed for the weaker 32auto cartridge could take the pressures of a hotter cartridge like 7.62tok.

Guns like the PPSH41 certainly can handle it. I don't think the casing design matters as much as the gun's design to handle the extra pressure to a more powerful round for which it wasn't designed. . I think that's what blastattack was referring to.

We need a caliber to convert .25 acp to now... a .22 or .17

Has anyone ever actually done this?

This may be my chance to get my hands on a CZ 27 pistol...

The limitations are generally the magazine, if it can hold the 30 reid. and the barrel and how complex the locking system is in it. straight blowback aren't to bad depending on how they attach to the frame. if the barrel has timed locking lugs that brings in a bunch of problems that would need a cnc machine to produce. All what can be milled out of a 1" -1.25" barrel blank.

The CZ 27 is a straight blowback, but the barrel does look like it needs some light machining. I'll have to look into it further...

If someone has access to a CZ 27 magazine and some .30 reid, and could test if it would hold the shells, it would be much appreciated.

what caliber is the 27 in ? if its 32acp it should be able to be done in 30 reid. as a 30 reid is a necked down 32 acp.

The CZ 27 is indeed a .32 ACP pistol.

That one may not be possible to do with the tooling epps has. But i will talk to the gunsmith and find out for sure.
