Ok, so I see Ballester Molinas clones out there that I assume are not interchangeable at all with the standard 1911, and then there are the Llamas that look like the real thing and smell like it, but I've heard different things about their interchangeablity. So what is interchangeable? I'm looking for the lowest priced 1911 that will accept generally available replacement parts including a 400 Cor Bon conversion barrel. Appearance doesn't matter. By the way, am I the only person who dislexified Ballester Molina into Molester Ballerina?
