This is why the first premise of the thread is flawed- you should never be buying guns "for the group". You may as well open up your safe to any friendly face and let them pick what they will for free. What works more effectively for standardizing a group is being a reloader amongst a group of people that don't want to, or don't have the same machinery that you do, and having them trade with you in the same way they would in civilized times. the end goal of any shtf situation is never to ride it out and hope for a return to the normal given by others, but to form a new society formed by consent and contract, trading value for value from you and those you value company around
Revolvers are not completely idiot proof. You can get a squib load like anything else and damage the barrel, or jam up the cylinder, or get someone who thinks fanning a hammer is a good idea, or loads high primers into a gun and tries to force it to work, or get inside the action without a clue how any of it works and leave yourself a pile of parts.
For the man who intends on it eating ammunition loaded by someone with know how, and cleans it occasionally and not tampering beyond his knowledge, any gun that fits his purpose will serve him. The biggest advantage that both revolvers and pump/break shotguns offer is flexibility- there are few guns out there that can truely claim to fire whatever ammunition you put through without an adjustment of the gas system. A revolver will happily fire three loads of top notch .357 and tear through a ballistic gel block, and then fire three mouse-fart 38s that barely punch 8 inches. A shotgun is much the same given the enormous artistic austistic freedom you get with a large weight shotcup- make the weight of the thing in the shotcup match the powder charge and inside diameter, and it WILL go bang, whether that's slugs, buckshot, toy cars, bouncy balls, dildos, onaholes or pictures of merkel.
