Yes, there have been a couple. At least one company (Coonan) has built a semi auto pistol that fires the .357 Magnum cartridge. A much more common find would be handguns built in the .357 Sig caliber. This is a bottlenecked .357 cartridge intended to duplicate the performance of the .357 magnum, but in an auto pistol cartridge.

SiG P229 in 357
100-1000 depending on what condition of "average" you are talking about.
a 357 cal. revolver cartridge WILL fit a colt 357 python. Also, a 38 special will fit a 357 cal. python. The 357 sig cartridge will NOT fit a 357 colt python................ The 357 sig cartridge ONLY fits the sig model pistol For clarity.....the sig 357 is a pistol. But, the 357 python is a revolver................
