A few importers here in the states have imported a handful of "post dealer samples" but the market is quite limited. Post dealer samples are mainly marketed for military and law enforcement sales. There is little to no market for them in the USA.
Only police departments and Government agencies can puchase post '86 dealer samples from Class III dealers. An 07 Class II manufacturer may purchase post samples for demonstration purposes with an approved law letter stating that the agency would like a demonstration of that specific weapon with the possibility of future purchase for official use only. Post '86 dealer samples are not available to the public, and may not be purchased for personal use.
