As over 80% of criminal confrontations occur under reduced lighting conditions, you need a good light as part of your defensive package. Surefire makes many; their G2ZX is a very good choice. Its collar allows it to be used with the Rogers/Cigar/Syringe/Sure-Fire technique. The included strap is long for my technique, but you determine and practice what works best for you. Do not wrap it around your wrist; make sure you can slip your finger of thumb out of any loop. The center hot spot is very adequate and the corona gives good edge illumination. I choose both Surefire and Optics Planet for top performance.
Pros: Illumination level, ergonomics
