4. Actions of Revolver Single-action revolvers - the trigger performs only one task, when the trigger is pulled the hammer falls, firing the handgun. Double-action revolvers - as the trigger is pulled two actions occur. The hammer comes back and falls forward to fire the handgun.

5. Advantage of Revolver it is an old standard weapon it safer for inexperienced users to handle and carry mechanism allows the trigger pull to be better misfire does not put out of action it will handle satisfactorily old or new or partly deteriorated ammunition that would jam

6. Disadvantage of Revolver bulky to carry grip or handle is generally not as good as that of pistol hard to clean after firing slower to load harder to replace worn outs or broken parts worn out or poorly made weapon is subject to variable accuracy

7. Hammer Slide Ejection Port Muzzle Mainspring Cap Frame Trigger Guard Trigger Grip Safety Magazine Front Sight Rear Sight Slide Lock Magazine Release Button Thumb Safety Barrel

8. Action of Pistols Semi-auto operation When the pistol is fired, the slide moves to the rear, ejecting the spent cartridge and usually cocking the pistol in the process. The cartridges located in the magazine are forced upward by the magazine spring into the path of the slide. When the slide (under pressure from the recoil spring) moves forward, it picks up and pushes the next cartridge into the chamber, ready to be fired again. Automatic operation The firearm can fire continuously as long as the trigger is pulled. Selective These fires either on automatic or semi-automatic by using the selector level of the firearm. Ex. Glock Pistols

9. Advantage of Pistol better grip more compact for the same fire power easier to load easy to replace worn out parts gives greater number of shots easier to clean greater fire power and greater ease of fire no gas leakage

10. Disadvantage of Pistol jam can prevent firing misfire stops functioning deteriorate the magazine spring it is kept loaded poor trigger pull more dangerous to handle it throws empty shell and leaves evidence cannot fired from pocket
