I have the CVA and the Western Powders 209 plugs for my Optima pistol. I was curious if there was any performance difference and there isn't really.
I have a couple other CVA long guns that use the quick out plugs and all have been replaced now with the CVA plug. I have 4 factory plugs that I intend to modify as Ron does. I have the bits on order and they should be here next week. I also have the fixings to make a jig similar to the one Ron used for holding the plug while drilling and holding the flat head screws as well. I'm anxious to see if the converted plugs do as well as the CVA 20- plugs or the Western plug. I'll get an up-date in here when I have had a change to work the plugs and loads on paper.
