I picked up a 61 Navy Colt clone awhile back. I already had one Pietta '61 and wanted another. This one felt a little different, and when I got home realized why. The entire thing is slightly smaller in size than the Pietta. The kicker is the FAP in a diamond stamp under the barrel, which is a Pietta trademark I am told. The barrel is tapered and the parts will NOT interchange between the two guns. Not even cylinders or grip frames. Any one else seen one like this? I conversed with Allesandro (sp) Pietta via email, and he said that Pietta never made a smaller framed 61. Thanks. DM
