frame sizes

Mr. Suponski, I can imagine why you would forget about the 1 1/2 frame. You are trying to keep one under the radar!

Yup.

I measured a few 410s and they are indeed 13/16. Are the repros different?

The 0000 is the Repro. Austin, did you measure a true 0000 frame Repro? I once did but have misplaced my notes.

The 0000 is the Repro. Austin, did you measure a true 0000 frame Repro? I once did but have misplaced my notes. Your chart shows a dimension for the 000 frame that does not agree with TPS, page 527. The Parker Brothers .410 was almost always built on a 000 frame. As I understand it, all 0000 frames were made in Japan. 00 frame .410 Repro barrels are usually marked 0000, but it is not a true 0000 frame. They are mismarked barrels installed on 00 frame 28 gauge receivers.

Bill ; The table on pg 527 shows DIM A as 13/16 as I found on the 6 000 frames that I measured. The question is - does the 0000 repro frame measure 13 /16 ? or is it 12/16?

The 1/16 inch per digit or 1/16 inch per zero size progression indicates that 000 corresponds to a 7/8 inch firing pin separation. Do any 7/8 inch separation guns exist? There are a few 20 ga hammer guns that are close at 29/32.
