Haven't seen one of these in years. They were welded around the barrel hood. Were used for sky marshal training in the 80s. Must have serial number. Now, why? Years ago a dealer in Louisville National Gun Day had a contract to destroy pistols. He used to strip the parts off prior to destruction. Gives you chills doesn't it. Anyway I bought a complete parts set for a P228. You see where this is going don't you? I know it's a long shot, but this is bugging the heck out of me. Now, I know they sell an 80% frame out of Canada. That is just too much work. Thanks for looking. No pictures naturally.
