Well, you certainly lost me. How does moving 10MM 1911's from CDP to ESP have any effect on needing a diferent gun for SSP?
As for the revolver thing, one could certainly solve that problem for for less than the cost of a new gun, let alone two new guns. A new 4" barrel from Smith would run around $100 and labor for the change from most smiths would be in the $50 - $75 dollar range. Weigand charges $150 to cut your existing barrel to any length you want, crown it, recut the forcing cone and install his interchangeable front sight system, add to that the savings of not needing a new holster, speed loaders, pouches and the such and the investment is not really that big a deal.
Personally I think revolver shooters should have to play with the same restrictions the auto shooters have, if it fits in the box it's good, if it doesn't fit it's not good. I would make the allowence that cylinder diameter would not count as part of box measurement.
Looking forward to your comments.
