Magwells for HK

The SFP9, VP9, and Mark 23 each have different lower frame dimensions, and magwells are model-specific. On the SFP9 and VP9, a magwell adds the competition reload geometry that the factory configuration does not include — a wider, chamfered opening that reduces the margin for error on the incoming magazine under stage pressure. The Mark 23 has its own frame dimensions and corresponding magwell options. A compatible base pad is required for all; confirm on the individual product page before ordering.
