The Z59 tail cap fits on several Surefire models such as the 6P, Z2,
C2 and G2. In my opinion, it's a necessary upgrade for any of these flashlightsâ€”especially if you are using them in a tactical situationâ€”since Surefire ships them all with a twist-on tail cap.
I tried this tail cap on two different flashlights: the 6P LED and the G2 LED.
The Z59 Tail cap is niceâ€” it works great on both lights. The Z59 has a smooth action and is engaged more easily than the tail caps which are stock on some of the other Surefire lights such as the E series. The on/off switch of Z59 is also recessed a bit more than the tail caps on the E series, so even though it does engage slightly more easily, I have not had a problem with the light being accidentally turned on in my bagâ€”I don't use the lockout feature.
The Z59 is just about the same length as the stock 6P tail cap and less than 1/8 of an inch longer than the stock G2 tail cap.
As of now, I am using it on my 6P LED since the twist-on tail cap on the 6P takes a bit more effort to engage than the twist-on tail cap on the G2.
Like everyone else: I wish Surefire shipped all of their lights with this tail cap instead of the twist-on tail caps.
Pros: Makes your light easier to use
Cons: This tail cap should be stock with all Surefire lights
