I am aware that this is preferably hunting flashlight, so I know that twisty is better than push-pull. But the light can also be used for non-hunting purposes (my case) and for that I would prefer to have a different way to use it. Push-pull is more suitable for single hand use, like the On The Road flashlights.
In any case, I find the ZT40 is a good and sturdy flashlight, with good quality and brightness!
