Upgrading a duty or carry pistol magazine is a straightforward way to increase readiness and flexibility without changing your firearm. Whether you’re preparing for extended range sessions, competition stages, or duty use, a reliable high-capacity magazine designed for the specific pistol geometry is essential for consistent feeding and secure locking.

MEC-GAR SIG SAUER is a 17-round magazine purpose-built to fit newer Sig Sauer P229 and P229 E2 pistols that feature a wider taper. Shop this product

Fit and compatibility

This Mec-Gar offering is specifically intended for newer P229 and P229 E2 frames with the wider magazine taper. It will hold up to 17 rounds of 9mm Luger, giving shooters a notable capacity increase over standard double-stack magazines. Important: it will not fit older P229 pistols that use a narrow flatsided magazine—verify your pistol’s magazine well taper before purchase.

Why the design matters

Experience matters when it comes to magazine geometry. Mec-Gar has a long-standing reputation for producing durable, well-tuned magazines that feed reliably. The wider taper of the newer P229 platform allows the magazine body to present cartridges at an optimal angle for the feed ramp, which reduces failures and improves lock-back consistency when using high-capacity springs and followers.

Capacity and caliber considerations

This magazine is rated for 17 rounds of 9mm Luger. 9mm Luger remains a top choice for defense and training because of controllable recoil, high magazine capacity, and broad ammunition availability. Using a 17-round magazine means planning holster, carry, and training adjustments to accommodate the slightly extended profile and weight.

Price is straightforward: the magazine is listed at $30.59, offering a cost-effective upgrade for those who want additional rounds without replacing the pistol or making major modifications.

Practical recommendations

Match springs and followers to your intended use—range ammo, duty loads, or defensive hollow points—and cycle the magazine through multiple load/unload cycles to ensure smooth feeding. Keep an eye on fit: if your P229 is an older flatside model, this magazine will not seat properly. For purchase, warranty questions, or to check stock, Check current availability.
