Copper John's just not for me all though I don't have any real reason to dislike it but I have heard of the pin's being fragile .I like all the sight's I have here Cosmic,Spott Hogg Real Deal,SureLoc Lethal Weapon and a Toxonic's ,which i can say are all good sight's but I have noooo room left in my stable's for another sight unless it's a Hogg it.
Good luck Terry I think it's probably a good deal so go for it .
