Walt,
You state that: "The Bulgarian Maks are apparently pretty good, but note: NONE of them are military surplus. These are all NEW PRODUCTION guns, most of them made in the last year or two. (None of them qualify for Curio & Relic status, while most of the other Maks do.)"
This is contrary to my understanding. I believe that there were both military surplus and commercial Bulgarian Maks being sold - with the former being somewhat more desirable. I can't prove this, but your comment surprised me (I thought/think I have two military surplus Bulgarian Maks).
Empire Arms, which seems to have a good reputation for knowing what they are doing and being honest, has the following description:
" BULGARIAN military Makarov semiautomatic pistol (9x18) mfg. 1966-1980 in Sofia. All-matching numbers, excellent (slightly-used) condition with minimal holster-wear but perfect bore and functioning."
What makes you think ALL Bulgarian Maks are of recent commercial manufacture? I'm more curious than concerned, because mine are both well made and work perfectly, so I don't really care. But I am curious. I don't think their exclusion from the Curio & Relic list necessarily says anything about their age or origin (most Maks couldn't make the list based on age). I assumed the Bulgarians are not included because they have been imported more recently, when it is perhaps more difficult to get guns classified as C&R. But that's just a guess.
