Hey Tinker,
Just as an observation
When Adirondack Jack (a good friend of mine) was developing the C45S, I was at the same time developing the 45 Squirt in parallel. We commune'd alot.
We both found whether in rifles or pistols, accuracy did not seem to suffer from the dreaded "jump." Decided the distance is so short, the bullet didn't travel far enough to go anywhere but straight ahead into the throat. Being a long term Gunplumber, I just naturally look for things to "fix." I always consider Bullet Jump.
I had a really nice set of USFA .45s with 3 1/2 inch barrels that shot really well and off a rest at 20 paces or so grouped around 1 1/2 or 2 inches with either 45 Colt cases or C45S cases. I fit a pair of 45 ACP cylinders to the guns just cause I'm OCD about some things and the difference in accuracy was ZERO to the naked eye.
Your Sheriff's are Righteously KOOL!!
