Thanks for the kind words Mark
As you know I'm not in this to make money I'm into it to have fun modifying my little Daisy model 95 .
So when I make or find things that can help me or others why not pass them along.
I went back to my original drawing and drew lines across the top and bottom then checked the measurement and came up with 1.91" so your good, the angle of your measurement may be the very small difference ?
The trigger pull on the 1938RR that I put the trigger in has a really smooth trigger pull, it moves about 1/4" to 3/8" before release and is very consistent.
I did find the the more power the gun has the more spring is needed to keep the plunger from pulling off the sear plate. The spring I used appears very heavy but it actually doesn't increase the pull that much, in fact I think it's lighter than the original RR set up.
I just talked to my friend who has the RR and he said the pull is lighter than the OE but he also said dont put your finger on the trigger unless you are ready to shoot as there is no free play.
I used a spring from a sewing machine, I will get a picture of one and post asap.
I will also show ya were on a sewing machine you can find one.
Just dont tell your wife I told ya to take her sewing machine apart !
