Carver Custom's updated magwell for the M&P strikes a happy medium, making it our No. 1 recommendation. It's big enough to be a full-on competition magwell, yet relatively compact compared to others of its type. The Carver fits a niche between the smallish SSS "ESP" model and the full-on SSS "Limited" -- which offers a very large funnel indeed. High value for the price Legal for most practical competitions (except carry optics+production USPSA, SSP division IDPA) Designed to work with Taylor Freelance basepads Works with virtually all basepads -- including stock magazines. Same profile as Carver Custom "Open" magwell, but relieved inside to accept factory basepads. SUGGESTED PAIRING: The "Triple Threat" and TF +3, +6, and +10 models all work well with this classic Bobby Carver design.
