Gik-tal, I STRONGLY doubt that claim. The Tokarev magazine is too long to fit in the 1911's grip, and the Tokarev round just pops out of a 1911's magazine due to its smaller diameter. I have both next to me and I just checked. This, coupled with the fact that someone last year on here was talking about wanting a 1911 converted to 7.62x25 and everyone told them that the round was too long for the action. It's simply not true. It cannot be done.
As for guns chambered in it, I'm pretty sure that, besides that one Sterling, the CZ-52 and Tokarev itself are it.
