hmm...I'm also going to get Milsig M17 but I think I go for cqc. It is because I fancy box magazine and with cqc it'll be easier to carry. Even though it's polymer material, from all reviews I watched on youtube everyone claim it to be very well made and durable. Think it's something worth to consider
Got mine Sunday at Miltac had some problems with it firing full auto even in semi auto mode. But after a few tweets of the trigger it was fine. First strikes in it are awesome would definitely recommend the elite.
