I remember it. Was a pretty big thing when came out. I remember, I think his name was Larry Kelly, hunted with Contender pistols. He magnapoted his barrels. I had about every Contender barrel made when I was a youngster. Never got any magnaported. Funny though years later I got a magnabrake made for my 300 RUM factory barrel. I don't know if they were the first to make a brake but I know I got mine done in 1999.
Thanks for pic. Reminds me of the old days. I have a great long term memory but short terms sucks....
