After reading responses and following up with a little research, I did my best to put aside a natural disgust for plastic guns and be as objective as possible.
Went to the shop and ordered a .45 UPS Tactical, which arrived two days later.
The gun was larger that I expected and felt weird even in my big hands, naturally something within was rejecting the light, toy-like feel of the plastic handle.
Field stripped the pistol to find a whacky looking spring, lots of plastic in the bottom, and terribly dissapointingly thin slide rails... how will this be able to sustain abuse? almost looks like it would chip off with a tap of a wrench. The slide rails engaged four little steel tabs protruding from from the plastic lower, Glock style, nothing impressive here. The inside of the barrel looked kind of like a Glock barrel. I was thinking I just paid a grand for a fancied Glock, actually, a flimsy looking glock with a plastic leaf-like trigger that looks like it can be ripped off with a push of the thumb.
Already missing the feel and classic lines of my 1911's, I fought hard to overcome my aversion for the strange new feel of this large, top-heavy clunker, purchased 500 rounds ranging from weak to +P, and walked into the indoor range area of the shop.
Keeping and open mind can sometimes be rewarding, this is what I found:
-The large, akward feel of the grip became more comfortable as the shooting went on, I began to feel the pistol was a part of my hand and my control was absolute... I guess the term "ergonomics" is something more than smoke and mirrors.
-Aiming with the large protruding sights was so easy and quick, I found myself wondering which one of my best handguns handled like that.
-At first I was wondering if something was wrong while shooting at 20 feet, but then I realized all the bullets were going through the same hole. 200 rounds made one single hole 1" in diameter.
-The "flimsy" trigger was, I hate to admit, just perfect. Crisp and just light enough, and something I never though about before: it felt like it was perfectly positioned.
-Shot the last 100 rounds from 75 feet, slow fire, and all the bullets were inside a 4" circle. For me that is without precedent.
-The felt recoil, even with the +P loads, was the lightest of any .45 I ever shot before, by a large margin. I'm always tired after four or five boxes with my 1911's, however I broke in my USP in one sitting and I was ready for more.
-The pistol was shot out of the box did not malfuctioned in any way, however I was expecting that as a minimum.
For those of us who don't believe a century old design can be radically improved, man, are we wrong or what. I guess in the long run time will tell, but If at this point I didn't say so far this is the best performing of all my pistols, I'd be telling a big lie.
I still hate the plastic, but less than before. This pistol has grown on me in a way none of my previously owned Glocks could have ever come close to.
My favorite gun will always be a 1911, but now I know it is for purely sentimental reasons. The initial performance of my new USP tactical left a far better first impression than any other new handgun I've purchased in 26 years of shooting. I will blast the hell out of this this pistol in 2006 and I'm looking forward to it.
