Corlinda has one. We were surprised how closely they match the Colt Mustang. Even to the point that some of the parts are interchangeable.
We discovered that they won't run well with the Colt 380 Mustang mags, even though they look the same.
The Colt will shoot well with either the Sig, or Colt mags. That doesn't make much sense to me, but that's the way the work.
It is highly concealable, and easy to rack the slide, and easy on the hands to shoot. Sig did it right when the designed this little pea shooter.
This is the Sig
This is the Colt
