Be safe and SMART out there, people!
When I’m shooting with new shooters, or even experienced shooters I will NOT put a gun in their hands unless I KNOW they can handle it. There isn’t a shooter out there that I won’t make their first gun a .22 Rifle, or a .22 full-size revolver.
Still those guns are EASY, and we might quickly scale up to a rifle in 7.62×39 or .45 ACP, but only once I see their form is GOOD. Form is EVERYTHING, and good form means even a small person can handle a fairly powerful gun, but with crappy form even an all-steel .38 Revolver, or 9x19mm will hurt you.
Unfortunately in this case it killed somebody. It could also end up killing somebody else if you let a round go over the berm, or bounce one off the floor of an indoor range ceiling. Know how to shoot, and shoot well before you start teaching new shooters, and then work UP new shooters.
One reason why I have a LOT of different guns is I like teaching new shooters, and having lots of guns means you can have guns that will interest new shooters, but also all the proper guns to work up into guns that will give them what they want.
Yeah, if you want to shoot a full-house .44 Magnum on your first day of shooting, you CAN DO THAT! Just it will NOT be the first few guns you shoot, and it may be a bridge too far.
