SureFire D3 Defender
First introduced as a common sense evolution of the SureFire 9P, the D3 Guardian featured the same head and tail as the SureFire 9P along with a body designed with an integrated pocket clip.
Initially marketed under the product name of Guardian, the D3 was later joined the two-cell D2 as a part of the Defender line. As a result, there are at least three variations in how D3 bodies were engraved – Guardian, D3 Defender, and D3.
Owing to its shared design with the P series SureFire lights, the D3 can can easily be configured into rechargeable or TurboHead versions.
