i have a colt mk IV series 80, that i bought off a guy a couple years ago for $350. it appears to be stainless with pachmayer grips. what can you "knowledgable types" tell me about it? is it a good gun? i have just plinked with it a few times. someday i want to do some upgrading, like an extended mag, slide, and saftey release. maybe a new barrel, competition hammer and trigger, or a compensator. just looking for info and opinions
thanks
