Magpul SL Polymer Lower Grip Module for HK94/93/91 - Black

The Magpul SL Polymer Lower Grip Module for HK94/93/91 is a purpose-built ergonomic upgrade for owners running HK roller-delayed rifle platforms and semi-shelf clones. If you're working with an HK94, 93, or 91, or their civilian equivalents, this grip swap addresses one of the most fundamental contact points on your rifle—and does it without sacrificing the gun's iconic profile. Magpul engineered the SL module with a modern grip angle and textured polymer body that gives you confident control whether you're at the range, in competition, or in the field.

Built from injection-molded polymer reinforced with corrosion-resistant steel components, the SL module is made to last through thousands of rounds. The grip features Magpul's proven TSP (Textured Surface Pattern) for a secure, non-slip hold in wet or gloved conditions. Fire control access is noticeably improved over stock—the optimized angle puts your hand in a more natural position relative to the safety selector and trigger pack. You'll also appreciate the clear HK "Navy-style" pictograph markings that show Safe, Semi, and Full-Auto positions at a glance, eliminating any guesswork under stress.

The module accepts Magpul MIAD/MOE Storage Cores, so you can stash cleaning patches, spare batteries, or other essentials right in the grip. Installation is straightforward—it's a drop-in fit on compatible receivers. As a bonus, the SL module counts as one compliant part toward 922(r) requirements for imported MP5 clones. Note that it's compatible with three-position S-E-F and Safe-Semi trigger packs, and works with Magpul ESK and S-E-F/Safe-Semi SSL polymer trigger housings, but not metal trigger housings or swing-down receiver designs.
