Description
Sig Sauer P226 Plus 4 Magazine Base Pad – Designed for standard capacity .40 S&W magazines, this base pad adds four (4) rounds to your existing magazine. The result is a reliable, no-nonsense increase in capacity for your P226 without needing a complete magazine replacement.
Key Benefits for Your P226
This base pad is built for the Sig Sauer P226 chambered in .40 S&W. It fits standard capacity magazines (often 12-round) and brings them to 16 rounds. Installation is straightforward: remove your factory floor plate, slide on the Plus 4 base pad, and secure it. No special tools or gunsmithing required.
Real-World Fit and Feel
The base pad adds minimal length to the grip, keeping the magazine well within the frame for a natural hold. The dimpled bottom surface gives you tactile identification in low light or under stress – a practical feature for range sessions or competition. The pad locks securely in place with a positive click, and the polymer construction matches the durability of your P226.
