Trigger plate size

[David Penland]

Are all trigger plates the same size and interchangeable? I have a Miller single trigger on a 12 gauge 1 1/2 frame I would like to put on a 20 gauge 0 frame?

That will not work. The 0 frame plate is narrower. Sizes 1 through 3 are the same.

Trigger plate sizes are, as a rule, frame size specific - however, they are each finish-filed for an ultra-superfine fit.

Thanks for the quick answers!
