    Found this on another site:

    Here was the question: How do I know if my 16 gauge is on a 16 gauge frame or adapted to a 12 gauge frame?

    This will really help guys who want to purchase 28 gauges to make sure it's on a 28 frame and not a scaled down 20 frame.

    Distance between the firing pin holes:

    12 Gauge 1 1/10 - 1 1/8 inch
    16 Gauge 1 1/16 inch
    20 Gauge 1 inch
    28 Gauge 15/16 inch
    .410 7/8 inch
