Stillife Posted February 2, 2013 Share Posted February 2, 2013 I recently acquired a very unusual EAA Tanfoglio Witness it's a 9mm gun with a 5.0" slide and barrel that are ported with rear black adjustable target sight and totally fixed front (it looks like it was milled integral to the slide/not removable). The slide reads "Ultra" Model IPSC Approved. I can't find much info on this model designation so I contacted EAA and told them the serial# and they said the gun was imported in 1997 as a Limited Pro 9mm. Needless to say I'm a bit confused. It is a match quality chamber and quite accurate from a ransom rest but frankly the stock trigger is long, heavy, and wicked gritty and jumpy in both DA and SA. The Henning Flat Trigger System and a EGW hammer/sear seems like a perfect fit to tighten up this gun. Can I convert it to single action by simply removing the double action interruptor? Or do I need to install the EGW hammer/sear kit to go full SA? Link to comment Share on other sites More sharing options...
CHA-LEE Posted February 4, 2013 Share Posted February 4, 2013 Since you have an old vintage pistol your first task is to figure out if the frame is a "Large" or "Small" frame design. You can do this by measuring the outer dimensions of the magazine that came with the gun. If its a large frame pistol you should be able to use the Henning Flat Trigger kit to make it a SA only setup. This would "Work" but you will still need someone to perform a trigger job on it to make sure all of the trigger components are optimized. Link to comment Share on other sites More sharing options...

After 15-20 1911 trigger jobs it cant be funtamentally different. Will the Henning/EGW parts work on a small frame?

CHA-LEE Posted February 5, 2013 Share Posted February 5, 2013 Yes, the Henning and EGW parts will work on the small frame pistols. Link to comment Share on other sites More sharing options...
