of all the calibers out there, Americas Sweetheart 22LR is my absolute favorite. I have the big calibers, but the 22 is such a verstile round and can still get a lot done in a pinch, not to mention how easy it is to have a few hundred rounds on you. For Nostalgia, I will go with the 10/22 just because you can do so much with them. But I have a hankering for one of those SW 617 Masterpieces, i will get one some day! I just got the Sig P322 last month, and im having a blast with its 20rd mags. My first suppressor is still in jail and I have a feeling its going to be a game changer! My new P322 below! Photo was before I got the oil off from the factory!
