I picked up an EM-1 since I'm somewhat of a Spyder fan and it's definitely a unique part of Kingman's marker past. After doing a little research, it seems that the factory regulator/ASA mounted below the grip is somewhat of a POS. Of course, being a Spyder, none of the connections are standardized, so the front grip isn't attached with normal ASA threading, but something smaller. It -looks- like 1/8" NPT but I'm not positive. Apparently back when EM-1s were semi popular, people took off the Spyder foregrip and replaced it with a BKO/B2K ASA adapter, which then allowed them to slap whatever reg they wanted on. After some googling it seems that B2K parts are not exactly easy to come by anymore.

I had the brilliant idea that maybe I could just throw a female Stab on the bottomline instead of the Kingman reg (PPS goodness is always a plus, and I figured a dust nickel would match the cast-chrome looks of the EM-1 nicely) and just keep the foregrip adapter, but when I went to the PPS website I noticed they make a "Direct" Stabilizer with 1/8" threading on the output as well. Anyone know if I can just screw a direct Stab into the input port on the EM-1 body, and plumb up an On-Off ASA to the bottomline?
