Z59, Z41, Z44, McClicky tailcaps -- differences?

[pnwoutdoors]

Can someone explain the clear differences and the pros/cons between the various common tailcaps available for the SureFire 6P style bodies?



Z59

Z41

Z44

McClicky





I have done quite a bit of reading, but most people simply refer to the designations without any description, already knowing what they are. Trouble is, I haven't been able to determine what the primary differences, pros and cons are between all of these.



Thanks,
