Re: Z2 or G2Z
That's the regular Z2 (plus, if you click on the pic, it enlarges to show the "Z2" printing on the side) -
Interestingly enough, that's supposed to be the FBI standard issue, and for various other LE agencies. If I'm not mistaken, it was based on a combatgrip theme for the SureFire 6P line from FBI Special Agent Bill Rogers (retired). The G2Z obviously came later. I personally prefer the G2Z - feels much lighter and the tail cap grooves make for an easier transition to turn the cap for constant-on with one hand. Too bad my department doesn't make THAT or the Z2 a standard issue. Ahh heck, at least the G2Z price is very reasonable anyway.
