Depends, A "Single Action" revolver, such as the Colt Peacemaker, carried in the old West, DID have to be cocked before each shot. A "Double Action" revolver, such as a current day Smith & Wesson, does not require that the hammer be cocked- it CAN be- or the trigger can be pulled, and the hammer will rise and fall.

I also own one (different model #), and my best estimate is that it was produced in the mid- to late-1970's.
No known sn data published. Probably early 1900's

It means that you have to pull back the hammer for each shot.
A Smith and Wesson M&P model is a 6 shot revolver in 38 Smith & Wesson Special caliber. The MP or M&P stands for "military and police".To disassemble the revolver, first remove the grip screw from the left side of the revolver as the revolver barrel faces to the left.When the grips are removed the side plate will be fully visible.Remove the screws from the side plate.To remove the side plate, hold the revolver to the horizontal position with the side plate facing down. Do not pry off the side plate as that will damage the side plate fit.Sharply rap the now exposed grip frame with a wood or plastic hammer until the side plate loosens. Continue to rap, and the side plate will fall off along with the hammer block, so be sure it falls on a padded surface.At this point most internal parts will be visible and accessible.The cylinder can be removed by sliding the cylinder crane to the left and out of the frame, while holding the cylinder in place.The cylinder will now be free.To reassemble the revolver, do the above in reverse, making sure the hammer block is in place and the side plate seats correctly.You can tap on the side plate with a wood or plastic tool to seat it properly.Replace the cylinder crane and cylinder. Be sure the correct screw is used to hold the cylinder crane to the frame.Replace the remaining side plate screws in the correct place along with the grips and grip screw.Holding back the hammer slightly, or with the hammer cocked, look in the gap between the hammer and frame to be sure the hammer block has been replaced.A word of caution here: know exactly what you are doing before making alterations or repairs. Revolvers are delicate and expensive machinery.
