Last night was the first time I have competed. Several months ago, I traded my SIG P220 for a Smith & Wesson 625-5". I swapped guns because I happen to shoot revolvers better than semi's and I wanted to continue carrying .45 cal. The 625 uses moonclips which speeds up extraction and reloading over individual cartridges. Moonclips are also faster than speedloaders, IMHO.
That being said, there were six shooters on the line last night, including myself. The other five were shooting semi's. I believe 3 had 1911's, and 2 Glocks. I had no trouble keeping up with them in terms of extraction and reload times. I do not know exactly how fast the reload times were, but with 144 shots fired (all timed courses of fire) I never ran short of time.
If you can get a hold of a Jerry Miculak video where he shoots and reloads the 625, it will give you an idea of what is possible.
Hope this helps,
Steve
