I picked up my new Beretta Nano at my local gun shop today and went straight to the range to try it out. I put a bit over 100 rounds through it. Overall I'm happy. I love the feel of the pistol, and how it fits my hand. It points very naturally and is very comfortable to shoot. I tried three different loads in it, and it swallowed everything without a hitch. On the rest it shot very well. Nice groups at 10 yards. Offhand, well, let's just say I need some more practice!! (I also am way overdue for new glasses. That's my excuse and I'm sticking to it!!) :)
The only complaint I have is the trigger. It is pretty long, and feels sort of "mushy" for lack of a better word. Just not very positive. Not sure if there's anything that can be done with it or not, but I'm sure I'll get used to it. I'm going to run a bunch more ammo through the thing and then I'll report back.
Now I gotta start thinking about a holster!
