    Hello guys. I am new in here. I've built several medieval crossbow, but now I am planning to make a simple but reliable pistol crossbow for leasure. 

    Is anyone have any diagram of a 50-80 lbs cobra pistol crossbow trigger mechanism? I can imagine the mechanism is as simple as the trigger pushing the string upward but I wanna see if I can push the efficiency of that trigger style by copying the diagram of that kind of pistol crossbow. Thanks  Smile

    Welcome, Lunkprab. I haven't laid hands on this particular toy, but I've been curious enough to try to research the design but haven't come up with anything clear on the release mech. I was more interested in copying the arming mechanism. I've put together a few pistol size crossbows, with a few different lock/release mechs, I guess any design you like from a full size weapon can be scaled down a bit to work. The advantage of that cobra/armex system is how quick and painless it is to cock and shoot! I've considered buying one a few times just to take it apart and see exactly how it works.

    Sorry for the late reply.  I had one of these for a while.  It was very cheap and toyish and not very accurate, so I got rid of it.  The mechanism is a simple pin or notch lock, where the trigger has a "tail" on it that ends in the pin (all molded in one piece) that pushes the string out of the notch.  Very simple mech.  I don't know where one could find an actual diagram of it.  I wish I'd kept mine so I could take it apart and post some pics. Crying or Very sad

    edit: Btw, the two "prongs" of the cocking mechanism on these do a great job of separating the serving at the points where they exert force upon the sting while cocking.  Not sure how one could avoid that.  Maybe wider prong tips?
