This was an interesting thread to read. Other than Gunhohulk, no mention at all about the prototype serial number. In years past, there used to be a ton of talk about the significance and rarity of these models. I guess that knowledge has dropped off the horizon or something. Oh, well.Congrats on picking that up! I was watching that auction with envy and if I wasn’t a CA resident that has to deal with the BS of a roster I probably would have gotten involved and ran it a bit higher. My consolation prize was that I found a Shorty .40 that same day at a local gun show for a decent price.
I think the XPX…. Serial indicates it was the gun they used to develop the Shorty 45 and if they had marketed the gun better it would have gone for a higher price. If you look through guns international you will find a couple XPX serial range guns that have documentation and the whole package that the sellers are trying to get 10-13k for. That seems pretty pie in the sky but those guns could be worth more than their standard run counterparts.
OP, I recommend searching the forum with keywords like prototype or PC test, and stick to this sub-forum. I'd also suggest sending for a letter. Something that has a rarely-seen serial beginning with an X and having a low numeral at the other end might have some interest. I used to follow these threads religiously and for that reason I suspect it's more significant than the other posters do. Now, it's been a while since I read about these guns, and I think I've forgotten more details than I care to admit. Anyway, good luck and good acquisition!
