what the pirate says is sensible. if you want full metal be prepared to pay a hefty price tag. you can get full metal guns nowadays but not all of those from ANY of the other manufacturers work like a dream as any of the TM guns out of the box.

it's really up to you.
I recently got a TM M4 S-System and compared to the other full metal guns i have had in the past, the weight is very much like them.
- DTP metal body M16 w/M5 RAS unit & G&P QD M203 long
- Systema full metal M4 RAS w/ SP M203 long

Full metal body's are lightweight now, it's just the cold touch you get when you feel it that is different. Metal bodies can only take so much stress and depends on what you do with your guns when playing.

Also, you lose the easy take down feature if you switch to a metal body and if you break a tab it is costly to replace the whole body. i hope TM release the M4 S-System body as an aftermarket part so we can replace our bodies if we need to. I'd replace the ones on my other TM M4s if the price is right.
