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
My friend has just got a M17 CQC and I must say it is really nice gun, it has a nice weight to it and also feels nice when holding. This has made my mind up and I have just ordered one.
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.
