The 1931 Fabrique Nationale (FN) Baby Browning is a small blowback-operated semi-automatic pistol designed by Belgium-born Dieudonné Saive chambered in .25 ACP (6.35x15 mm).The frame has a full-length dust guard extending to the end of the slide, and an area behind the trigger was relieved to allow the user to maintain a more substantial grip than with the 1905 version.With the exception of special order nickel-plated units and the above-mentioned versions, all of the 1931 Baby Brownings were finished in chemical hot blue.The halt to exports to the US in 1968 was mandated by the Gun Control Act of 1968, which was precipitated by Robert Kennedy's assassination involving an Iver Johnson manufactured revolver.In 1984 a Canadian Swiss screw machine shop, Precision Small Parts, Ltd (PSP) entered into a technology transfer and production agreement with FN to manufacture the pistol.PSP's owner Joseph Maygar Sr. had a long working relationship with FN dating back to the days of the Hungarian Resistance Movement of WWII.In 1985 the Canadian federal authorities forced PSP to transfer production of the Baby Browning pistol frame (the essential part according to the legal definition of a firearm) to its Virginia, US facility, though the Canadian side of the company continued to manufacture the slide and detail parts for the pistol (except for the magazine, which was contracted out to Mec-Gar of Italy).At that time, Austria was known to be a trans-shipment point for armaments for the Middle East, and presumably the State Department did not want a large number of Baby Browning pistols ending up in that region.Faced with many more parts than they could use in a reasonable timeframe for their own PSP-25 pistols and now dangerously short on cash, PSP became financially exposed and was on the brink of insolvency.Due to numerous municipal and state lawsuits of gun manufacturers at the time (prior to the Protection of Lawful Commerce in Arms Act of 2005) no prospective partners were interested in the opportunity.[12] The Bauer Automatic utilized a different auto safety spring and the barrel was removed (and the slide released from the frame) by twisting it clockwise 45 degrees, rather than counterclockwise, as is the case with the FN Baby Browning.
