Sig Sauer P229 (Pre 2010 MFG Date) Magazines

Known for delivering unmatched reliability under stress, the Sig Sauer® P229 is the gold standard of duty pistols, favored by civilian shooters, law enforcement agencies, and military personnel worldwide. Introduced in 1992, this double-action/single-action (DA/SA) handgun features a lightweight aluminum alloy frame with a double-stack magazine well for superior strength and unwavering corrosion resistance, while the stamped steel slide comes equipped with a standard three-dot sighting system for intuitive target acquisition and optimal clarity in any target or personal defense environment. Further, the Sig P229 is a versatile centerfire pistol, available in 9mm, .40 S&W, and .357 Sig, making it the ultimate sidearm for police and military personnel, as well as civilian defense shooters.

In 2010, the Sig P229 E2 ('E-squared') was introduced as an attempt to make the large frame gun more ergonomic for smaller hands, and featured a reduced grip size and reduced reach trigger bring the trigger face back more than 13 mm (0.5 in). This, of course, resulted in a smaller magazine well, which is not compatible with older P229 magazines.

What Does “SA/DA” Mean?
Single-action/Double-action.

Single-action/Double-action pistols allow shooters to fire the pistol by either pulling the hammer back with their thumb or racking the slide before pulling the trigger (single-action), or by simply pulling the trigger and forcing the hammer to pull itself back prior to striking the firing pin (double-action). The single-action stage requires the hammer to be cocked (manually or mechanically) before firing, and offers a light, crisp pull, ensuring accurate shot placement and improved handling. A double-action pull, on the other hand, is much heavier and requires an intentional pull. With single-action/double-action pistols, the first trigger pull will be a double-action pull and much heavier. As the slide travels rearward, it will automatically cock the hammer, allowing you to fire with a light and crisp single-action pull with every shot thereafter, making the single-action/double-action system one of the most reliable and safest hammer-fired pistol designs in the world.
