I had a Colt Pony for several years. I had the stainless version - Here is a pic:
I think I would have preferred the SA version - almost like a mini 1911. But, at the time, this was the only one being made - it was DAO.
I had 1 problem w/ it - the slide stop was peening the slide - basically, the hole in the slide for the slide stop - the metal around it was bending back, the more I used it (the slide locks back on the last round). I sent it in to Colt right after I got it, because it did it very fast, and they replaced the slide. It started to do it again, so I rarely shot it. Finally ended up getting rid of it...
Don't know if it was a consistent problem or not. But, I wouldn't buy another because of this. If not for this, it would have been a good gun - recoil wasn't too bad because of the weight of the gun. Although, the stainless version was very heavy. The aluminum frame version would be lighter.
I think the Beretta Cheetahs are nice 380s, but of course, they are big. Berse and SIg make some nice ones - look almost like a PPK. And, I think I plan to buy a Keltec one myself... Because, I want something smal. The Keltec is a little bit smaller than the Colt versions, if I am remembering correctly.
