- You forgot a different extractor and ejector. The cases are different.

- you cannot get away with just having an extra slide.

- In theory, since the case heads are the same, you can probably
- do this (for the same reasons that you couldn't do it in the above ex-
- ample).
-
- The only problem I envision is that the .380 auto is a good bit shorter
- and may not feed reliably from a 9x19mm magazine. Of course you could just
- hack up a 9mm magazine by putting a 2mm spacer-strip in the back of it.
- (and then use a file to shorten the follower).
-
- Of course -- to avoid feeding problems, it might be best to start
- out with a single column magazine and shorten it.
-
- If you were really studly, you might be able to fashion a chamber
- insert to make it into a sub-caliber; and then silver solder it in. This
- would require veeeery precise machining work. I would lean towards the
- Beretta since the barrel is steel. The Glock barrel may have some of
- that funky "tennifer" coating in it which makes machining (and silver
- soldering) difficult.
-
- Ob_SIG_Reference: of course the SIG would be the ideal candidate
- for doing this sub-caliber conversion on: it never has feeding problems.
- And the barrel is steel. (Of course, you would buy an extra. No sense in
- trashing the perfectly good -- and matching serial number -- original
- barrel.)
