Perhaps an aside, but -
How hard are these things to make if they want to? I've recently become enamored of 32 caliber guns, but officially S&W stopped making them a long time ago. Still, the 432PD does show up occasionally - I bought 2 in the last year, one from Bud's that was defective, sent back to S&W for repair and condemned by them as unrepairable. I bought another one on Gunbroker to replace the bad one (S&W could not supply ANY 32 as a replacement). Both of them had been manufactured within the last 15 months or se, according to a thread somewhere on this forum, but never appeared in the catalog as far as anybody can tell.
So - is it possible that the 327 and/or 386 might just show up on an intermittent basis in the future, as small batches are produced from time to time and just supplied to distributors without hitting the catalog as officially available?
Now the 432 is just (IMHO) a 442 with 6 smaller holes in the cylinder and a smaller diameter barrel insert, and I assume it's no big deal for S&W to reset their CNC machines to handle these small variations on blanks/billets that otherwise would get 0.357" holes in 'em. Would either the 327 or 386 be (relatively) easy to cut from parts that otherwise would go into other, more popular models? If so, maybe they too will show up from time to time, but in ways you have to keep an eye out for rather than being able to order like any other model.
