I shoot a full-size 1911 in IPSC competition, and a compact in IDPA. We had an IPSC match last weekend that I knew would include a 50yd shot. I'd never fired the gun at anything more than 25 yards away (and rarely at anything more than 50' away), so I set up a target at 50, and fired a couple of rounds. The gun was hitting about 3" to the right of center - which was not perceptible at shorter ranges. I go two D-zone hits (low) at the match. At an IDPA match, the scenario involved engaging a "sniper", first at 75 yards, then 50, then 25. This was to simulate the sniper working his way toward the shooter after discovering he was under fire. My 3.5" barrelled gun had never been fired at anything more than 50 feet away, so I had no idea where it would shoot at 75 yards. We were allowed to "shoot as much as you want", so I sent two each at the 25 and 50, and fired four at the 75 (Okay, for you "tactical" types: two at the 75, two at the 50, two at the 25, and two more at the 75). I had two decent hits on each target. Even if scenario is unlikely, it's comforting to know that you can hit a target, under pressure, even at longer ranges.
