Model 66 Cylinder Movement

[RMS272829]

I spent sometime today cleaning my new-to-me 197x's Model 66-1. I noticed the cylinder had a movement of 0.020" along the horizontal direction when the cylinder/yoke was swung out of the frame. Is this amount of movement/looseness acceptable? I don't believe my N frames have this much.

The cylinder would fall out without the external lug when the cylinder is fully open. The specific play is not important until you close the cylinder.

0.020" is the precise width to accept a drop of CLP !

Does not sound like excessive clearance with the cylinder open. Some external lugs do allow less movement of the cylinder, but as long as the cylinder is not dragging on the lug and the lug keeps the cylinder from falling off of the yoke, it's fine.
