Frame size, anyone noticed this

[Dave Moore]

All of the guns are pistol grip. Last night I measured the gap between the front and rear triggers on 2 0 frame guns and 2 1 frame guns that I have. On my guns, the space between the triggers is narrower by 3/16” on the 0 vs the 1. You can see it in these pics.

I don't see any pics?

As I said before, Parker only used one trigger bow, only differing behind the bow for straight stocks. Early lifters used a larger trigger guard.
Any variation between triggers comes down to trigger shape. Of 4 one frame guns, one rear trigger is quite far back, but the other three, both front and rear triggers, are very much the same. These three match, with less than an 1/8" difference, to the eight 0 frame guns I just measured. I also dug out my profile and contour gauge and find virtually all these guns to have the same trigger guard bows, the only difference being the curve behind the spur on the straight stock guns.
