The ASP Metro Defender D2 in Onyx (ASP part no. 55154) is the maker’s key-ring-sized OC pepper spray device, the model that was formerly sold as the Key Defender. The Onyx version is the low-profile choice, with a machined aluminum body, brass actuator and replaceable Heat insert. It has a five foot range, a thumb-release safety and an O-ring sealed dispersal port. It is meant to disappear on a key ring until you need it.

Key Specifications

• The OC formulation is 10% oleoresin capsicum with 1.4% major capsaicinoids, the concentration ASP says matches law enforcement use.
• Effective range is five feet, with conditions able to change the actual distance.
• The body is machined aluminum with a micro-knurled surface for a secure grip.
• A thumb-release safety helps prevent accidental discharge, and the O-ring sealed dispersal port keeps the unit sealed.
• The solid brass actuator has a hole for attaching the device to a key ring as an alternate carry method.
• One Heat insert is included, and the replaceable insert design lets you reload instead of replacing the whole device.
• The finish is Onyx, one of the five Metro Defender colors ASP offers.

Frequently Asked Questions

What is included? The device includes one Heat (OC) insert. The maker also offers inert Test inserts for practice.

Is the Metro Defender D2 refillable? Yes. It uses a replaceable insert, so when the insert is used or reaches its recommended change date you discard it and load a new D2 insert. Heat inserts and inert Test inserts are both available.

Is this the same as the Key Defender? Yes. ASP renamed its original Key Defender the Metro Defender D2. The insert size and compatibility are unchanged, and only the name and packaging differ.
