Interesting. Is it the model that makes room for the extended dust covers that the STI 2011 styles use, because there are more than a few models and it confuses me, lol.

Edit: Look what I found while scouring the internet. Its supposed to be a Hi-Capa 4.3 holster from Snake Three according to this thread. I don't know who or what snake three is, the only information I can find about snake three is the word "snake" in snake skin.

Does anybody know what holster this is? It would solve everybody's problem with trying to find a perfect holster for the 4.3 model guns.

I think I've found out what the unidentified holster in the post above is. It is (not sure what brand) a SERPA holster for the Glock pistols with a level 2 retention. It looks very similar to the BlackHawk Level 3 SERPA Auto Lock Duty Holster for the glock. Mind you this would only fit the Hi capa 4.3 if you had a stock grip with the square trigger guard.
