I got rid of one of my useless guns at a buy back a couple months ago. It was a double barrel Cobray .410 derringer and while it would be a fine tackle box gun, I don't fish and it could be a decent snake gun for woods walking, but it's too heavy and clunky, a 12oz .38 with snake shot would be much easier to carry. They were offering $200 for handguns, so I jumped on it and will never buy a Cobray derringer again. The only other gun that would come close to being useless would be a .32 Mag Heritage revolver I have and was shooting recently. It shoots high and left and I remember when I got it I only shot paper with it, so I knew where to hold when shooting paper and was used to the sights. After years of shooting other guns with way better sights it's like this thing is unshootable now especially for steel plates. I love the way it feels in my hand, the trigger is fine, the lockup is super tight, I reload .32 Mag so ammo isn't an issue, it groups very well, but the sights are just so bad and off that I'm seriously questioning why I still have it. I think that the Raven .25 I have is actually more useful given I can actually hit what I'm aiming at with that gun. I guess at the very least I could use it to test Lil' Gun handloads from it to make sure they wouldn't blow up my Charter.
