Not bashing the taiwans, but any assembly line you will see a few mistakes on the product every now and then mine was this: I just bought the gun today 1/29/05 I made a 1Hour and 45 minute drive just to get it. I get home and gas it up the gas leaks violently out of a screw located at the bottom of the gun directly underneath the pin which punctures the carterage. I took out the screw only to find out only half of it was done with pipe dope and the other half was left with nothing so the air leaked out of the side with some teflon tape and some pipe dope i fixed it no problems.
Conclusion:
Overall, it seems to be a very nice gun the grip is something to get usefull but out of all pistols I have owned every one needs something to correct a leak this one was the easiest.
