We may have a failure to communicate. Almost ALL .22s are rifles, not shotguns (there ARE a very few .22 shotguns, but are quite scarce) And Marlin made several dozen different model .22 rifles. Which model? Bolt action, lever action, semi auto, pump? My Marlin 39A rifle, which has an exposed, external hammer (most are internal) moves through an arc of about an inch.
Try to pull it back. DO NOT LET IT SLIP OUT OF YOUR CONTROL!!!!!!!!!!!! If it doesn't move, take it to a gunsmith.
The hammer will be in the cocked position. Nothing will happen until you pull the trigger.
One shot for each pull of the trigger. The trigger does not cock the hammer.
1. select powder and shot 2. prime the pan with gunpowder and pull the pan back securing the gun powder in place, pull the hammer back to half cock or "safety". 3. turn the rifle over and pour the remaining gunpowder down the barrel. 4. drop the ball down the barrel and ram it with the ramrod. 5. use the paper cartridge as a wad and put that down the barrel and ram it with the ramrod. 6. turn the rifle over and pull the hammer to full cock. 7.fire!
The way to use the back of a hammer is to place a sticking up nail in the back corner of the the hammer, than place the head of the hammer on the ground. finely pull the handle of the hammer away from the nail.
Some handguns can only fire if the hammer is in the cocked position (typically, pulled back). These are referred to "single action." Other handguns can fire even if the hammer is down (not cocked). Pulling the trigger brings the hammer back (cocking) and then fires when the trigger pull is complete. These are considered "double action." They not only Fire the pistol, but Cock it as well.
You PULL or draw the hammer back to start the swing of the hammer on the initial swing, and pull it away from the impact point to start your next swing You PUSH the hammer forward to start the hammer toward the impact point
Look at the back of the breech. If there isn't a hammer, it's hammerless. Hammers are those things that stick up at the back of the barrel. On a single action gun you have to cock them (pull them back) before you pull the trigger. Pulling the trigger cocks and releases the hammers on a double action. All the firing mechanism is inside a hammerless gun.
Both! You can cock the hammer and pull trigger for single action. Or, for double action just pull the trigger straight through.
To cock a semi automatic shotgun simply insert the round you wish to use and pull the slide back then take the safety off and fire.
Company long out of business. 15-150 USD depending on specifics.
You take a gun, you load the gun, you pull the hammer back, and you pull the trigger....its that simple
