    HW45 front sight extension. Why?

    I've just got another 45, this ones an original, single power .22 with shoulder stock and front sight extender. I understand this is to make it more suited to use as a carbine, but I've driven from Kent to Cornwall today, I'm tired and befuddled and simply can't work out why this would work?
    Looking at it all that should happen in my mind is the POI is lowered. I can't test it until tomorrow, so until then could someone please explain it in short, easy to understand words why?

    Because the additional weight of the stock, and the fact of being fired from the shoulder, change the way in which the recoil affects the gun, moving the POI down. They tame it a bit, and the muzzle moves up less between trigger break and the pellet leaving the barrel.

    A bit like POA shift when adding a muzzle weight to a springer rifle.

    Or that heavier bullets shoot noticeably higher than lighter ones in magnum revolvers (because they exit the barrel slightly later in the recoil stroke).

    Or SMGs fire at a slighter faster cyclic rate from the shoulder than with the stock folded.

    Cheers Geezer! I had thought that, but then thought raising the front sight was the opposite of what it needed?

    Like I said, I'm tired, and thanks to sampling a bottle of donated Hong Thong, Thailands premier blended imitation Scotch, also now emotional!

    Would it move the poi so much as to need the sight being moved? Would it be anymore than the difference between the half power and full power settings on the hw45?

    Whatever the reason, it works. In fact I still had to lower the sights to get the pellets down to the target!

    What a fab little carbine though. Its much easier to cock with the stock, very stable and great fun!
    I fitted a kit to it many moons ago and took a coil off at the same time, and now with the stock fitted the noise is out of all proportion to the tiny movement the recoil creates.
    I've kept it on the opens for now as that suits the look, and after half an hours practice I'm getting about a 1" spread at 10m. I know that would have been instant and then improved upon with a scope, but I really like the simplicity.

    Who needs rifles?

    If you find the standard Weirauch shoulder stock comfortable you must have arms like a gibbon!...had one years ago and found it way too long...
    I had the foresight extender as well and assumed it was necessary because your eye was now much, much closer to the rear sight...
