Hi Folks,
Copy and paste here. I don't own an old Colt:
The thing is there are two types of reproduction Colt 1873 single action revolvers. The most common type uses a transfer bar safety, meaning you cannot fire it by pulling back the hammer and releasing it. The other type, patterned after the original Colt, has a two or 3 step safety notch in the cocking mechanism, so if the hammer is drawn back even 1/4 of the way, it will catch on the safety notch instead of dropping and hitting the firing pin. Also, my understanding is the Pietta reproduction he was using had the transfer bar safety. Even if that is not correct, he would have had to pull the hammer back just a little less than 1/4 of the way and then release it to have it fire. This seems incredibly unlikely. Or the gun would have to be defective, something the armorer would have caught and if she had not then certainly Baldwin would be highlighting that fact now.
