did some searching on patents. find some very interesting stuff when searching the patents. found some pics I have never seen before. heres the links. Pistol, whose housing is composed of plastic Friedrich Aigner, Wilhelm Bubits Pistol having a prestressed firing bolt Friedrich Aigner Pistol with trigger locking mechanism Friedrich Aigner MA1 upgrade Handle part for a handgun Elmar Bilgeri
Back some months ago when people were discussing the possibility of getting tri/trap night sights made, I did a search of patents related to tri/trap sights and found a few with Bubits' name on them.
Very interesting indeed. I never bothered to check on patents filed before. The references to Glock and Walther also are surprising. I thought there would be more mention of the metal frame that Steyr has while Glock only uses plastic.
