I purchased a Norinco 1911 A-1 back in the '90's, chucked it into my safe and forgot it. I've recently taken it out and have been shooting it. The thing double fires at least once during a range session. I believe it has a disconnect/sear problem and know that I'll have to take it to a qualified gunsmith. My question is would it be worth investing the money to have it gone through, replace sights and make it a reliable shooter or should I sell it and look elsewhere? Any opinion would be appreciated. Thanks.
