9mm and 22 Mag. A couple of my buds had 9mm's back in the day, one a BHP and the other a 5906. I was liking them very much and always thought that I'd buy a BHP for myself. As soon as I bought my 45 ACP I forgot all about the 9mm.
My first rifle was a 9422M and I had so much fun with that rifle that I once thought I would have a collection based on them. I was the king of all my shootin buds who had 22 LR's and I was the one with a Mag. It didn't take long for them to jack up the price of 22 Mag ammo to almost the price of 45 ACP ammo. That disenchanted me a lot.
