I think I will abandon the idea.
I have 1911s to shoot 45 ACP.
A new "drop-in" cylinder would be terrific....but....
....it would still need fitting.
And, if sent to Colt would need shipping.
Plus.... I don't CARE what 45 Colt ...SELLS...for. There are just none that I can find locally and California requires FFL transfer of ammo.
Reloading is another issue. While I have saved all the cases I have shot in the SAA New Frontier, there then is trying to find ...primers.
I have plenty of SMALL pistol primers. But no large.
I have enough boxed 45 Colt to last my short time left. And anyhow I mostly just ...look...at the gun.
Thinking even MORE clearly today....
.. I don't shoot my revolvers nearly enough anyhow.
So....thanks for all the suggestions. All were considered.
Fine forum.
