And keep in mind, NONE of the super-tiny single-stack polymer framed autos has gotten out unscathed.
American Rifleman reviewed the current crop of micro .380s a few months back (time flies, it all flows together, no more than a year ago). My recollection is that all of them, including the Sig, except the very most expensive, had functioning problems.
I suspect small autoloaders are harder to get right than larger ones. KelTec has a design (locked breech, half cock hammer on a tension spring) that seems to work well, and everybody's copying it.
I did hear a rumor (once, on Tom Gresham's Guntalk, talking to Bob Morrison of Taurus USA) of a .380
revolver from Taurus. Interesting, if true. It could be pretty darn small, and less problematic than tiny autos. At least until it's time to reload. This was last year sometime, and nothing's been seen of it, so it's probably Taurus vaporware.
I will be interested to see Ruger's micro 9.
