I shot the Champion earlier today. Actually did a little head to head comparo with another 1911 I just picked up.
The other gun was a Colt Commander with every add on possible. Hand fitted beavertail, hammer, sear, CMC trigger, novak sights, FLGR, ramp and throat job, everything. A real nice piece my gunsmith had built.
The Champion was pretty much stock with a round count of 200 rounds or so. The feed ramp has been polished, as well as the sear. The trigger is much improved, but still needs to be replaced. A lot of take-up and over travel.
I had better groups with the Champion. This could be because of the smaller GI sights, I had to concentrate a bit harder. I put three rounds into one hole at 5 yards one handed (the other was supporting a ballistic shield). Maybe it was just luck, because I'm normally not that great of a target shooter. Had a few stoppages with the Champion. It didn't seem to like the Chip McCormick mags, once I switched to Novaks it was good to go.
The colt was definately heavier being a all steel gun. But it was much more comfortable to shoot with the extended grip safety, wider ambi safety, flat MSH, and rubber grips. The extra heft did help with the recoil, but the Champion wasn't excessive by any means.
I would recommend getting the Milspec model over the GI if you can. I didn't care for the arched MSH, or the sights. Other than that it was pretty lightweight and a good shooter. For what I paid, $375 with a WC mag and 120 rounds, I would definately recommend it.
Note- We were running a tactical type course. All shooting was done standing, or one handed, or moving. It was pretty hard to guage the accuracy of a gun while doing this.
