X-Grip XGGL29-30 Magazine Adapter (Glock 29/30 using G20/G21 Mags)

The X-Grip XGGL29-30 is the cleanest way to run full-size Glock 21 13-round .45 ACP magazines in a Glock 30 without a ring of bare magazine tube sticking out below the grip. The G30 frame accepts G21 mags natively, but without an adapter the longer magazine hangs below the subcompact grip with an exposed gap that kills the firing-hand purchase. The X-Grip sleeves over the G21 magazine body and fills that gap, giving a full-length grip matched to the 13-round mag.

The result is effectively a G30 with a G21-sized grip and 13+1 capacity, the staged home-defense or nightstand configuration while the flush 10-round mag handles concealed carry. The adapter slips over the magazine and interlocks around the floorplate, no tools required and no modification to the gun or magazine.

X-Grip notes the XGGL29-30 fits Gen3 and Gen4 factory G20/G21 magazines; it does not fit Gen1 or Gen2 Glock mags. Verify the SKU, since X-Grip makes different adapters for other frame and magazine combinations.
