I have a somewhat old shotgun that has recently given me some problems. The hammer is not engaging the firing pin. The firing pin is not broken. I can eject the shell, reinsert it, and about 1 out of 20 times the shotgun will fire. My buddy, who is a gunsmith, says he thinks its a spring? Dry firing it does not give me a "click" .. Well anyway, all problems aside, the shotgun holds no sentimental value to me and I am considering fixing it and then trading it out. It is a S&W model 1000 super 12 that would be ideal for someone who hunts waterfowl. I see them sell for 250-500 on the internet.. Mine is in excellent condition (minus the firing problem which will be fixed.) I really don't want to put anymore money into the trade than what it will cost to repair the shotgun and maybe $25, because I am saving for an AR. Realistically I plan on taking it to the pawn shop and getting an even trade for a mossberg 500. Ideally I would like to push for a Remington 870. I plan on pushing the selling point that my gun is not manufactured anymore and 500's and 870's can be picked up at Walmart. Hopefully that will give me some leverage with the pawn shop owners who low-ball all the friggin time. I was thinking though... Do gun shows offer trades? There is one coming to town in a few weeks. I have never attended one, because I refuse to pay an entrance fee when there are over 20 gun shops within 30 minutes of my home. Also is a trade for an 870 a realistic expectation and should I push for that?
