Most issues like that are ammo related ...not usually the gun malfunctioning....or the gun was not maintained properly.
In shotguns, in my opinion - you get what you pay for !
Beretta is one of the leaders in the semi-auto gas gun market ...and they sell models starting at about $ 800 - $ 2,000 with a number of very good guns .... / Browning - Winchester have some good models Browning Maxus, Browning Silver, etc... $1,000 - $ 1250 or so / and Benelli has a number of inertia operated guns ....$1,000 - $2,000 .......and I'm not saying there are no other guns you should look at ....but if someone is selling a new semi-auto for $ 500 ...you may not be able to tell much by looking at it / but you have to wonder about the metallurgy and the quality of the internals.
I'll tell you a story about a buddy who bought and shot a Beretta semi-auto -- decent gun / low end model but still ....one day it quit cycling ...he asked me to look at it / when we took it apart the action was a solid block of "carbon" gunk because he had not cleaned it in over a year..and he was shooting 300 boxes a year...so he was flat out abusing the gun. It was not the gun or the designs fault ( and I still pick on him - for being an idiot / and the fact that it took me an hour to get the gunk out from under my fingernails ! ).
Personally I clean every gun I shoot - at the end of my range day --- but I am especially fussy with any semi-auto I choose to shoot / and it doesn't matter if I shot 3 boxes or 10 boxes..../ in a tournament situation - I'd clean the semi-auto between morning and afternoon sessions ( just so I don't have to think about equipment issues). Over Unders ...way less moving parts / I still clean them, but I wouldn't fuss with them between morning and afternoon sessions.
And partly because of that ...I've never had a gun fail in a tournament ( but any gun can break ).
