I recently bought a Pietta LeMat for my Christmas present and now want a Tower Of Power loading stand so I don't have to rely on the flimsy loading arm/ram/pivot that the pistol came with and frequently breaks. I need someone to verify the DIAMETER of the 20 gauge shotgun barrel (OD)that the cylinder revolves around. I used a vernier caliper on mine and I got a reading of .825" Is that the diameter of the loading stand pin I need for my LeMat or are there other various diameter dimensions I need to know about (I guess what I'm asking is my .825" OD reading accurate and nominal for the Pietta replica LeMats)?? THANKS for the assist and info!!!
