You are not limited to "strong hand cocking", many shooters use the "Weaver" stance and cock the hammer with their off hand.
You don't understand my point.
You're absolutely correct, you CAN use a Weaver hold and cock with the off-hand in SASS/CAS. The rules on gun modifications require it for most shooters, save those with the biggest hands and long ape-like thumbs.
Thing is, we can shoot Montados and other SBH/Bisley hammer slightly customized Rugers from the Weaver while cocking with the STRONG hand.
And that's the preferred technique for combat shooting, because otherwise you're forced to shoot two-handed and there may be times you can't. Either one of your hands/arms is shot up, or your off-hand is being used to do something else important.
When CAS/SASS limits hammer modifications, they eliminate proper technique. And I'm sorry if I offend, but I find that VERY offensive.
It gets worse. CAS/SASS allows unlimited internal mods. So you can spend $800 on a linebored cylinder and custom barrel, $200 on a Ron Powers drop-in action job and you're perfectly legal. Or spend $1000+ on a "Race tuned" (or so they claim) STI.
What you can't do is spend $35 on a mod designed to make the gun fit your hand, for safe and effective shooting in all circumstances.
I can understand rules designed to prevent an "arms race" but that's NOT what's going on here.
It's as if NASCAR allowed unlimited engine/tranny/suspension mods, but limited seats, steering wheels, gearshifts and their -=positions=- to just one fixed set, so most drivers are either squished up in there or stretching futilely for the wheel and pedals.
It's not "just the rules of the game", it's marked and obvious insanity. And you'll note that the horse-mounted rules WERE changed to something sane due to the requests of the richest participants - those with horses.
It's not just asinine, it's elitist asinine - the worst kind.
I had not heard of Western 3-gun until now but in reading the rules, it appears to be run by people who agree with me completely on where SASS/CAS had gone.
