I recommend revolvers to start those who want to learn to shoot handgun for several reasons
*They do not have any safety's-Which if you think about it is beneficial for our use. We want to keep everything simple here. including the amount of functions the firearm has like various levers, switches and buttons on some makes of guns can be daunting to the uninitiated. The more you try to throw at them the more they might get frustrated.
*They are safer than automatics-After a round is fired the action must be cycled in order for the next round to come into battery. In a automatic all that is needed is a slight release on trigger pressure and reapplication of pressure to fire again. This could result in accidental double or triple taps...I did it the first time I shot my dads .45 1911 when I was young. Its just not a good idea. The obvious option to this is to load 1 round at a time. This is a good idea as it will familiarize the shooter with the weapon and its workings fast. But a standard revolver is just impossible to accidentally double tap with normal target loads and a new shooter. Or any loads for that matter.
*Smoother action- Firing single action a revolver has a much smoother trigger pull than 95% of the Semi auto guns I've handled and shot. There are very few times double action is required in firing. Being charged by a bear or the occasional zombie is the exception.
*Super reliable-A revolver can handle light loads up to red line loads without fail of action. In a semi auto the ammo must be in good condition and powerful enough to cycle the weapon without being too powerful to crack frames and break parts. The revolver will eat anything you throw at it and more. you can load the cylinder of a revolver with full wad cutters, Semi Wad cutters, Round nose and bird shot loads and it will shoot one right after another without fail. Try that with a semi auto and you will give up in short order.
*Takes time- A revolver forces the shooter to slow down esp when shooting single action. It isn't a race...seeing who can throw down more lead never makes for good practice. Though speed loaders are made for revolvers its not the same as a auto shooter blazing one mag away after another. Also have the new shooter remove their finger from the trigger after each shot after they are acquainted with the weapon. this helps burn in good finger placement on the trigger. You can take this one step further and have them set down the gun or just remove it from their strong hand grip after each firing. Load 1 round in the cylinder at a time perhaps. This will cause them to make a habit of how they place the revolver in there hand. As well as getting used to loading and unloading to the point it is second nature.
*Ergonomics- Revolvers tend to have a better selection of grips available than with auto loaders. Look at your hand, its not shaped like the grip of a 1911. The small grip I have on the 63 works well esp for female hands. The magazine wells of pistols tend to dictate grip size and shape. Revolvers do not stick to this rule at all. This is why rounds like the .45 GAP emerged as a way to make a smaller slimmer grip for females in guns like the Glock.
Some additional tips I would like to add. Don't force a new shooter to shoot any particular gun. They loose interest if they are not having fun! DO NOT I REPEAT DO NOT give a new shooter a large caliber firearm. I keep seeing these videos online of guys given new shooters esp girls large guns like 12ga loaded with slugs or .50AE Desert Eagles. They end up hurting themselves /create a dangerous situation. Guy with the camera almost always laughs. yeah ok its funny if you get a guy who thinks he can handle a .375 H&H after shooting some .22's but thats a ego thing. Its just not cool when you are putting it on the unsuspecting and telling them to just "HOLD ON". Thats the kind of thing that turns them away from the sport. (end rant) At the end of each range session ask them what they learned today. I've been asking this for 2 years now whenever I'm acting as instructor.....you yourself can learn a lot from feedback. It also allows the trainee to reflect on what they have learned.
