i found lots of info on doing it, most from a guy i met down at taylors who already has one he did and luckily for me, had it there for me too look at, although his is a uberti, they are identical, the cylinders even swap and time perfect between my pietta and the uberti., the nice thing is since the firing pin on the C&B is offset to the right, swapping the firing pin and just notching the inside left of the frame notch for the C&B pin gets the .45colt pin where it needs to be, then just swap cylinders. all the frames are identical, when they forge the frames they don't forge this for c&b and that for .45/.44-40 etc they just cast a bunch of frames and mill them into what they will become later on so frame strength is a moot point. so its going to be a 2in1 gun like my converted walker. the guy i met did his because he shoots both competition black powder and sass, apparently sass doesn't allow the 73 c&b... not historically correct they say.. (this from a bunch of guys that dress like rodeo clowns in perfectly crisp and clean shirts)
i have all the parts coming, the measurements on this cylinder i got are dead on with the C&B cylinder, i'm just worried that ratchet is different,
waste of money? me waste money? nope,
$300 for the gun, 80 for the cylinder, 10 for the bushing, 20 for the firing pin...
cost of my project= $410
cost to buy both a .45colt and a c&b 73
cost of a pietta .45 saa = $449
cost of a pietta 73 c&b = $395
total= $850
not really wasting money
