A friend has the silver Beretta and I've fired it many times. It is a sweet gun and can take a beating. It's powerful, kicks hard, looks pimp, has realistic weight and is an all round awsome gun for gaming, plinking and siting infront of the TV reloading over and over with.
Don't waste your time with that TM pastic crap and spending oodles to upgrade it with an iffy kit, get it all at once with the KJW. If trades are what you want, they even make a version with trades but it costs like 1/3 and I don't know if it comes in silver. Personally, it hella ain't worth it spending what will end up being 50-100 bucks on some bloody numbers and a couple words. Metal is what counts for me.
