20Holster and magazine holder restrictions

• Suitable for everyday use. “Race gun” type holster prohibited. • The drop offset type holster is allowed in Single Stack division as long as the heel of the butt of the gun is above the belt per 5.2.11, and the rest of the criteria are met. • May not be manufactured or cut lower than, and must cover the slide up to, 1/2” below the ejection port (belt slide “Yaqui” type holster exempt). • When held in a magazine pouch or on a magnet, each magazine must be contained individually within the magazine pouch or individually attached to a magnet. Pockets are exempt from this requirement.

21Authorized modifications

• Milling of the slide to insert sights, add or remove serrations, such as cocking or flat topping, tri-topping the slide, lowering ejection ports, cuts that are minor and cosmetic in nature are permitted. • Duplicating features that are on a factory, mass produced slide available to the general public is permitted. Cuts that are designed to specifically or significantly lighten the slide, such as holes, or slots, are ruled as competitive advantage and prohibited.

22Prohibited modifications and features

• External modifications or features such as weights or devices to control or reduce recoil (such as, but not limited to, thumb rests or components which could be used as such). • Slide racking devices are prohibited. Cone and flanged barrels are not allowed. All • barrels must have a bushing installed, regardless of barrel diameter. This does not apply to pistols having a barrel length of 4.20 inches or less. • Slide lightening, cuts, ports, or any milling deemed to provide a competitive advantage.

23Permitted features

• External extractors, firing pin blocks, and other factory safety features. • Duplicating features that are on a factory, massed produced slide available to the general public. • Factory installed light rail attachments if the dust cover is no longer than 3.25 inches measured from the rear of the slide stop pin to the front of the dust cover.

Pistols made from components that duplicate the factory originals are acceptable. Frames must be metal.
