My grandfather just gave me his Colt Challenger .22 today. It seems like a nice little pistol, I'll be able to test it out next sunday. Is anyone familiar with this gun and have any info about it? I know its pretty straight forward, I used to shoot this with him when I was younger when we were hunting or trapping (he likes to carry it on his hip). I'm just curious if anyone has any stories to share or anything of interest. Thanks.
