i imported (and sold) some Unica and MTR parts and tools, as i have a Unica 6 Hunter and was interested (at the time) of becoming an importer for Tanfoglio's line of steel CZ-based frames for my own pistol-making ideas rather than enter to very crowded Glock and 1911 space. unfortunately after some successful orders i was told that there was a change in ownership and the export license would be renewed under the new company and owner who had apparently bought out the previous management team with VC and crypto cash. unfortunately that cash dried up and the VC took their ball once they had a big enough return, so the current state of the company is in bad, complete with violation of Italian firearms export and manufacturing laws as well as some finance stuff going on regarding scams/fraud with banks or laundering or something possibly crypto related.
very sad situation.
The example I saw had a FA, their was no pawl on it but it was there.
i have put hands on both a pre-sales Diemaco LSW, early Colt model 606A, and production Colt model 750's and none of them had an FA of any kind, only the shell deflector. a
Dutch export version sold by Diemaco as the LOAW
did have the FA present, although it wasn't functional. the Colt model 950 (now the Colt Automatic Rifle) also lacked the FA, but the LOAW had it. i assume it's a cost saving measure of some sort, since having a button pinned in place or non-functional is inexpensive vs having a split production line for finish machining. note that both Diemaco and Colt make the LSW/LMG variation and Diemaco has a license that allows both production and export as well as changes, so my assumption is that Diemaco kept the FA and just made it non-functional, while Colt had varying ways of deleting it entirely.
