Canada Ammo (and a few other stores, including some other site sponsors) have the T2 edition of the 1887: that has the barrel snipped to the minimum (470mm), and the butt cut off to about the minimum Over-All Length (660mm). This is done, of course, to mimic the nifty gun that the Terminator used one-handed while riding a motorcycle in the T2 film.
Is that the one you love, or would you prefer a more traditional one for cowboy style? The stubby grip on the shorty isn't very pleasant for multiple shots, and you probably won't have much success spinning it on the lever like Arnie did (but you can try).
Right now I only know of Lever Arms having original 1887 clones in stock; anywhere else? I think the importer had a bunch of these and decided they'd sell faster as the movie gun, so they were converted here rather than in China; might not be many left in full length.
I own the original Norinco, and have tried the shorty. Cleaning up is the usual for any Norc: dis-assemble and remove the grease, cycle some rounds and see if they hang up, maybe need to file/polish some rough edges and the chamber. If you're going to rely on it for CAS competition, you'll want to be thorough. Otherwise just use it a lot and it'll wear itself in, probably.
