Mike, neat guns. Do you know who modified them? Also, in your trading time, have you ever run across any Smiths or Colts modified by George Mathews of Downey, Ca.? I first saw pictures of his cut down M&P's as well as Colt PP's in the 1970 Guns&Ammo annual. At that time the article said he worked on everything up to and including New Services and Heavy Duties as well as everything in between. The ones pictured showed 3in. "King Type" rails and sights,as well as thinned "Bill Jordan" type trigger guards. I have run across many different cut downs but none of his. We ,SG-688, and I have tried to find any and all information on him but to no avail.
