No Prob's with mine, about a 1.000 shots so far. Different silencer as i thought the original was a bit loud, allway looking for advice to avoid problems. I'm carefull with mine but without knowledge, well you can guess the rest. Best pellets so far are AA Fields, LRG & FTT Allso Hobby, Superdome & S-H-Piont but those are light pellets. My advise for gaining advise. Every day tap in your subject in the search box, loads to read then place individual queries, not loads together. I like my .22 so much i might get a .177 to have a play with. Enjoy your S10 i think there ok !
