Glad to see you had a good day at the range with the
new gun.
I'm running that same ISMI 22# spring in my 4013 (after you posted about using them almost two years ago now) & it's performed perfectly with my full power .40S&W handloads.
I've had a few guns that I had to cut a turn or two off, so they wouldn't bind, but I checked my notes, & the original spring package, and it doesn't appear as I shorted this one.
I sometime use a lighter mainspring but the 4013 has a 20# Wolff in it so I'm surprised your
1014 didn't like the 22#.
As has been noted before, the ISMI springs aren't as hard to get back in the gun in subsequent assemblies as it is the very first time, which
is tuff.
Awesome thread!

PS: I disassembled my 4013 & verified the ISMI has not been cut off at either end.
