Base pads for Sig Sauer

Base pads for Sig Sauer replace the factory floorplate to add a grippy bumper for faster, surer reloads and—on many magazines—extra capacity (model-dependent). They’re also essential for magwell builds.

Why upgrade

• Speed & consistency: a larger, textured pad helps magazines lock in under stress.
• Added capacity: extensions provide extra rounds where allowed—see product notes for exact gains.
• Magwell fit: pads labeled magwell-compatible add the height/geometry to seat against the funnel.
• Durability: aluminum/brass pads shrug off drops better than thin OEM plates.

Pick your type

• +0 (bumper) pads: no capacity change; ideal for EDC or rule-limited divisions.
• Extensions: add capacity; some models require a spring/follower kit for reliable feeding.

SIG compatibility—quick checks

• P320 (Carry/Full/X-Series): match pad to your module and magazine body (17/21 etc.). Race funnels (e.g., X5 Legion) often need taller, magwell-compatible pads.
• P365 family: pads must match mag length (10/12/15). Some extensions include or require specific springs/followers.
• P226 / P229 (classic P-series): verify mag brand/body and grip style (E2 vs. classic panels). Magwell builds typically need extended pads for positive seating.

Install basics

1. Unload; control the spring while removing the OEM floorplate (eye protection recommended).
2. Fit the new pad (and spring/follower if supplied), ensuring the locking insert engages.
3. With slide locked back, insert a loaded magazine to confirm positive seating—especially with a magwell—and verify drop-free.
