Don't be put off by the TM polymer slides. It gives a fair bit of kick, not as much as a full metal pistol, but the accuracy is better because of it! I reckon the plastic slide is a plus rather then a minus.
I have a Strike Warrior, keep running it on duster gas. My Strike warrior feels very solid. MEU mags are very dependable though have a very small gas chamber. So don't expect to run through a whole mag of BB's without running out gas unless it's in the hottest summer. I underload the mags to about 20 BB's. The Warrior series does not have any need for upgrades and actually run worse with them.
I have no need for another pistol. It's purely for picking up and working without trouble.
