USPSA has a few different divisions that require different guns and equipment to be used giving every competitor the participate on a level playing field. Things like magazine length or capacity can be restricted, or other items like your holster type, location may also take you from one division to another. Divisions like production and single stack have a fairly tight rule set, where limited and open divisions have very minimal restrictions on what you can use and do to your equipment. This is not meant to be a comprehensive guide to the rules, but more of an overview of the highlights of each division to help make your selection a little easier.
If you are not sure what division your equipment puts you in, don't worry, just follow along below.
