Hello. Yes, the Beretta Model 84 can be carried in Condition One. These are normally quite well-built pistols and finished nicely. The ones I've shot and seen shot were very reliable and with a wide range of ammunition types.
Yep, the .22 is the Model 87.
I may be mistaken, but I think it's more like the model 85 .380 which uses a single stack magazine, and therefore is a little slimmer.
I had an 85, and thought it was too big for an eight shot .380, but would have made a neat .22 (as the model 87).
Put me down as someone who likes and owns an 87. Great gun. These medium-size .22 guns, like the 87 and Walther PP work better than the really small guns, and are more useful. Plus, with an 87, you can get the longer barrel from Beretta, and get a can for it (if you are so inclined).
Not so impressed with the same guns in .380. With the advent of well-built, reliable mini-9mm like the Kahr and Rohrbaugh, there is no excuse for carrying a .380.
