That is a monumentally bad idea. Did the photo come from a for-sale ad? I'd say that the value of that gun is nothing more than the value in parts. Someone might want the slide to do a caliber conversion. I'm guessing based on the bags of parts that he not only cut the trigger guard off, but also put a trigger kit in to lighten the pull. What an ultra-maroon!
Yep I remember when that "THING" was listed on Gunbroker.com and some wone linked the auction via Glocktalk,com, it got plenty of comments there at the time. Supposedly a Southwest of the US somewhat Federal Agent of an unknown agency carried it Undercover. I do not remember if it sold at auction or not, but a BBL and Frame and its as good as new.
