There are two types of loading in IPSC and they are classified as major or minor calibers. A 45 ACP lightly loaded will be classed as a minor caliber. Typically the velocity and weight of the round determine the class. I haven't shot IPSC in a long time but I believe the threshold velocity for the major caliber class was around 900 feet per second for a cast lead 230 grain bullet. I reloaded my own ammo using 5.2 grains of Winchester 231 powder. That load just cleared the major class. I also shot 9mm however that was always the minor class gun. It really was a 45 ACP game. The loadings rules are equal for everyone. The guns ran all over the place but the consistent winner shot what we called space guns. They were highly modified and often fitted with muzzle breaks. Such guns had a major edge over a stock over the counter pistol. I shot a stock Colt 1911 with very few modifications and I was never competitive. Now you can buy highly modified 1911's suitable for IPSC over the counter. It worth shooting with whatever pistol that you can use. The fellows are usually great guys and you can develop you pistol skills under stress.
The faster I go, the older I get.
