Any idea if a Ruger SP101 in 9mm could have its chamber lengthened to allow a 9x23 to be chambered? I've seen a similar conversion for S&W 686s on www.moonclips.com. They claim that the 686 so equipped will chamber and fire 9x19, 9x23, .38 Super, and other 9mms with a similar head size. They also state that .38s and .357s can be fired using a conventional moon clip, although the cartridge head expansion will render them unreloadable. The .357mags metric designation is 9x33R, so it should be ok on length.
Why would anyone want this done? Seems that it would increase the versatility of an already versatile weapon. The 9x19 loads are already pretty close to the short barreled .357, so the increased capacity of the 9x23 should allow them to be met or exceeded. Cheap 9mm Lugar or Blazer 9mm Largo rounds can be used for practice. In a pinch one could also use .38 Specials or .357 mags.

Feasible or shall I keep dreaming?
