I like a steel 1911 for my non-large hands. The heft doesn't hurt recoil reduction. However, I do shoot Glocks better in a tactical environment. I'm still waiting for Glock to release a Glock 17 or Glock 19 in single stack. That would be the perfect pistol for me. Anybody listening in Austria???
Being a machinist, I think there is something nice about the way a nicely made metal slide slides on a metal frame with little play (like in high-end 1911's, Sphinx, Tanfoglio, etc.), but I have no problem with plastic frames. Most of my handguns are plastic framed guns. They're lighter, and I think polymer guns look cool.
Steel slide (or aluminum alloy slide for 22LR) does not slide directly on a polymer frame (normally glass fiber reinforced polymer composite like the most popular Zytel-in that sense it’s not really “plastic”). There is always a steel INSERT bolted to the polymer composite frame on which the slide slides. A polymer composite frame is just for gripping the gun and it reduces weight. It doesn’t really carry any high mechanical stresses. For this, the frame doesn't have to be steel or aluminum, really.

I know that polymer guns use steel inserts. I've taken my guns apart before.
A polymer frame isn't just for gripping the gun. It still has to hold the various steel inserts installed together and take the forces imparted on them. As far as I know, the steel parts in polymer frames are not a single piece, but multiple pieces molded into the frame, that require the properties of the polymer to keep them there.
I was just saying there is a difference in feeling between short lengths of loose-fitting rail inserts, and full-length frame rails with just the right about of clearance to glide nicely.
An interesting discussion to be sure. I have shot both types but do not have enough "time in the saddle" with either to know which I prefer.
One concern/question I have, polymer and extreme cold conditions. Northern Canada can be cold and some plastics just can't stand up. Anyone who has experience with polymer and winter know about this issue?
Of course, the polymer composite frame (not just polymer) must also accommodate the steel internals. But the frame doesn’t carry any high stresses by itself, that’s why from the mechanical point of view it is just designed for gripping and reducing weight. The steel insert is not molded into the frame just pressed into it and pinned in a few places to the frame. For my Grand Powers it is sufficient to remove two pins and then the entire steel insert can be pried off without a big problem. Similarly for my Walther PPX. However, the steel inserts can be very different like those with two very short rails, like in my PPX, just for guiding the steel slide, or a full rail like in my Grand Powers where the slide runs nearly its whole length within those steel rails. During shooting all principal stresses are carried out by the steel insert and its parts. Not much stresses are transferred to the composite frame. The frame itself is NOT POLYMER. It’s a composite of short glass fibers in a polymeric matrix, mostly polyamide (nylon). Addition of glass fiber reinforces the polymeric matrix. Just pure polymer would be too weak. Nevertheless, after some time the polymer composite frame can be distorted to a smaller or larger extent around those steel pins that keep it together with the steel insert.

In an HK (I was using as a point of reference), it's different. The steel inserts are molded into the frame and the front and rear sections of inserts are separate.

I shot my M&P trough 2 winters ( outside range ), never encountered a problem. My fingers gave up before the polymer did.
