On my Springfield 45 XD, the slide is steel but the guides in the lower end are polymer. No problems with it yet. The same is true for my 9mm Bul Cherokee. I have 2 of these with about 2,000 rounds though each and no slide problems or even any noticeable wear on the polymer parts. The new generation polymers seem to be a great deal more durable than the old plastic that was used in some grips, etc. and would crack simply by slightly over tightening a screw. I've been impressed with the durability (so far) and the weight difference is incredible. I originally went to the polymer Cherokee simply for its light weight (permanent shoulder injury). I couldn't hold a Para on target for more than 3 - 4 magazines, now with the Bul and the Springfield I'm shooting in IPSC. I will admit that it goes against the traditionalist nature I usually have, and wouldn't have gone to polymer if I hadn't had this injury, but I have been very impressed so far.
