CRITICAL: Just be sure that someone--a shop or private party--does not try, intentionally or not, to sell or trade you a "short" .32 gripframe...UNLESS you want that. Many will mis-inform (again knowingly or not) that the .32 "Vaquerito" only came with the short GF. Not so--it's a very common misconception as many were made with the standard XR3 Red plowhandle too, even though for awhile the shorties did seem to predominate on the gun store shelves. Also be prepared for a seller/trader to claim, again sincerely or not, they do not know which they have.
I realize there are a lot of "again..." cautions here, but it cannot be overstated. More people than I can count have unwittingly ended up with a shorty, either thinking "that's all they (Ruger/store) had" or even not really noticing until they got the gun home and spent some higher quality time with it.
Someone more conversant with the part numbers here can alert you to which the shorty is if not otherwise self-evident, but my understanding functionally and structurally it is literaly a shortened "XR3 Red," and may still have those words, *in part*, associated with it.
Btw, I'm sure you will find many eager swappers, as a lot of folks want to do the opposite as you--either to a Single Six or larger-frame Ruger SA!
