I prefer steel over anything else, there's just something about the weight and feel of it.
Until recently, I only owned two polymer guns, a S&W 15-22 pistol, and a Kel-Tec SUB2000. I disliked polymer in general, but those two were only available that way, and they shot fine. A friend of mine had a Taurus 809, and it felt great, and it ran fine, so I bought one, brand new, and it's been a disaster. It's back at Taurus now, and I have little hope they will fix it. I passed up buying one of the Canik CZ-75 clones to buy it and I feel it was a huge mistake. If the 809 comes back and is still a dud, off it goes, and it will probably be the last polymer gun forever, or at least a long time.
