You want someone else to do your homework? Well, you have the Mustang { all steel } and Mustang Pocketlite { alloy receiver }, and the Mustang Plus II { extended frame, two more rounds, all steel.}. But don't forget the Colt Pony, the Colt Pony PocketLite, The Government Pocketlite and last but not least the .380 Series 80 Goverment Model. As far as the Mustang's go, the difference is what is the receiver made of, stel or alloy? Now, you didn't ask my opinion but I'm going to give it anyway ( wonderful thing about the Internet ), you would be better off with a current firearm that is still under warranty, either the Ruger .LCP or the Kel-Tec 380. All the others have discontinued, I have heard that Colt is revisiting the small auto again but don't know for sure.
