The ProMag SIGA5 delivers extended capacity for Sig Sauer P226 pistols without compromising reliability or function. This 20-round magazine transforms standard carry guns into high-capacity platforms for competition, training, and tactical applications.
What Makes This Different
Constructed from heat-treated blued steel rather than polymer alternatives, the SIGA5 maintains dimensional stability under stress and temperature variations. The steel construction provides superior feed lip integrity compared to aluminum magazines, while the follower design ensures consistent cartridge presentation. Internal geometry matches factory specifications to maintain the P226's renowned feeding reliability across all 9mm ammunition weights.Key Features
