Stratus Support Systems knoppind

That knuckle makes stowing the 870 on a vest or belt feel completely natural mid-drill, no more fumbling with the OEM pin. The detachable part locks in solid and hasn’t loosened after a few hundred dry-fire cycles. Exactly what I needed for breaching work.

The trigger pin swap took about five minutes and now the 870 sits rock-solid on my vest when we're stacking up on a door. That knuckle grabs my gear tight enough that I don't worry about it sliding off mid-movement, which was my biggest fear before buying.

Detachable knuckle design means I can rack the slide one-handed if my off hand is busy—that alone sold me. Fits the receiver pin slot without any wobble, and it stays put through a full day on the vest.
