Just to be sure you know....because some sites aren't to clear about it...the Satin Gray E2e and E1e come with the non-hex head while the HA has the hex. Meridian Tactical seems to be the only vendor that understands this. I bought my satin gray E2e from them. They still have the pyrex and upgraded clip unlike the E1 and E2 non-elites but have the smoothie head which I prefer.
just a note....I am not so sure now that the satin grey has the pyrex....the website information varies from vendor to vendor and seems to suggest HA gets pyrex and SG gets coated lexan.
