Yeah, cocking back the hammer is not needed for modern pistols because when you pull back on it to chamber the round it automatically cocks the hammer, and usually the pistol is all ready to shoot as soon as you pull it out and pop the safety off.
This is a common misconception upon gun designs. If you have a sigle action only gun you do have to cock the hammer before see any modern 1911 that's built to the A-2 Spec. However in the situation of a double only you cannot physically lock the hammer by pulling it back. and theres the option of a double single design where you can choose to cock the hammer back which reduces pressure needed to fire the round.
the benefit of cocking a hammer back is to reduce the trigger pressure needed to fire the weapon, very commonly (especially in the case of revolvers) trigger pressure is quite heavy and therefore adds to the tendency for barrel walk. This was overcome significantly by the introduction of the semi-auto design in which, after the first shot, you no longer had a long trigger pull.
also on point for the original post here. there are hundreds of guns chambered in the .22 cal range and currently most military forces use the .223 which is a variant of the .22.
And yes I do own guns if you think my facts are off, look them up yourself.
