.. maybe so - but so many say not to bother, but for the sake of £5-15, why not, when it could cost you 40+ for a spring or firing pin + fitting.
Personally I have no idea. im new to shooting - but read lots and still not entirely sure, so far I can gather the newer guns - in the last 10-15 years are not to worry about... Id rather not take the risk...
Im still waiting for info from Italy in regards to my gun (bought second hand, came with nothing). Id like a manual for it so I can strip and clean myself (thoroughly) Its been nearly a month though, I just have to sit tight and wait..
