I just looked at two Model 63 rifles
The hammer pin is .160
trigger pin is .130
Both measurements approx w/o taking everything apart, but you can easily eyeball the difference in diameter,
Rifles are 124xxx and 177xxx ser#s.
I've worked over alot of them and as far as I can recall the trigger pin was a smaller diameter than the hammer pin, but perhaps there were 'engineering' changes in there somewhere.
...like the plastic forend caps.
Would enlarging the hole in the sear to take the larger dia pin make it kind of thin in a couple of spots?
