Ok, first off I am NOT slagging Marstar in the follow posting, just laying out my experiances with a missing NP22 grip screw. I bought a NP22 from Marstar, great little gun, super price, great dealer. One of the screws on the pistol goes missing so I call Marstar figuring this should be a straight forward thing to buy from a Norinco vender. Sadly no screws in stock the guns out of warranty and I , out of luck going to Marstar. So I go to the range (Connaught) hoping against hope that its just laying there waiting to be found (fat chance in sand but hey stranger things happen). Anyways a police service is firing that day and I get talking to one of the members and he goes in the back of their truck and gives me a couple of used Sig grip screws (which tells me they "harvest" spares off old/worn guns). I am over the moon figuring this is done till I get home and find they do not fit in the Nork Pistol22. So now I am on "Plan C" and ask Jason if he can source a screw for the grip. Jason digs around and comes up with what he suspects is a CZ75 grip screw that works. Now go back to the first sentence and note again I am not slagging Marstar but I was disappointed that they did not stock something as simple and straight forward as a grip screw and the hoops I jumped through to find a replacement.
