And, in the US it was complicated.
Virtually all full-auto Uzis were in 9x19, with a smattering of .22lr and some .40ae (no bolt face change).
Semi-auto UZIs were available from IMI with 16" carbine barrels in 9x19, .45acp, and .22lr.
Some of those were SBR-ed to have original-length barrels.
I have heard that some full-auto carbines in .45acp were built, before '86, but not in any quantity.
Where the confusion may be occurring is that Ingram's MAC built the M-10 (aka MAC-10) in both .45acp and in 9x19. The M-11 was more compact, and in .380 (with the M-11/9 being an M-11 with a 9x19 chamber instead of 9x17). The MAC series of subguns is visually similar to the UZI.
