I put a Raven Pocket Clip on my Elzetta Alpha.
The Elzetta Alpha A323 has been part of my EDC for 2 years now. For all but a few weeks of that time I’ve been carrying it on my belt with a Prometheus Lights Titanium Pocket Clip, which works great on the Alpha. I changed over to the Raven Concealment Systems Pocket Clip to get the finger ring, which is just a large rubber O-ring that allows you to use your hands for something else without dropping the light.
