The PROMAG 10-round 9mm magazine for SIG P225/P225-A1 pistols delivers reliable, affordable capacity for shooters who want more rounds without switching platforms. Built to work seamlessly with these compact, trusted duty and carry pistols, this extended magazine uses heat-treated blued-steel construction paired with a polymer base and follower lock-plate for durability in the field or at the range. Whether you're training, competing, or running drills, having extra rounds on hand means fewer magazine changes and more time downrange.
Pro Mag engineered this 10-round magazine with a focus on longevity: the spring is wound from chrome-silicon wire and heat-treated to maintain consistent feeding pressure shot after shot. The proprietary DuPont Zytel polymer base plate and follower are designed to handle the demands of regular use without cracking or wearing prematurely. The blued-steel body resists corrosion during storage and transport, so your magazines stay combat-ready season after season.
If you own a P225 or P225-A1, adding spare magazines in higher capacity is a practical upgrade that costs far less than buying an entirely new gun. This mag works hard whether you're zeroing a new gun, practicing your draw, or stocking backup for a defensive role.
