Most failure by bending or breaking parts from hard racking happens in shotguns that have a single arm on the action slide tube assembly. The mossberg has dual arms and is notorious for being able to continue to function under adverse conditions. The Remington 870 also has dual "action bars".

Holy fucking shit you just watched John wick and rolled with it didn't you? That thing is the biggest pile of shit in the shotgun world. Issues? Fucking everything. You would be better off shooting yourself in a home invasion as that first shot is the only reliable one you are getting.
I don't think you have actually used a shotgun.
As a bonus the browning bps also used dual arms.
You see faggot the thing is all those shotguns mentioned that have dual arm pumps evolved because to men in swamps and fields, in the rain snow and mud, dust and dirt, running dirty old and mixed types and leingth ammunition racking hard under pressure and excitement.
