I purchased a Nano for concealed carry. It is an amazing little gun and is VERY accurate, even out to 60 or 100 yrds. There is a video of a guy hitting 5 out of 6 at 60 yrds and 4 out of 6 at 100 yrds, IIRC.
It has only a 6 shot magazine. Beretta has an 8 shot magazine that extends the grip half an inch, but even when I get an email alert that they are available the website says they are out of stock. It amazes me that they cannot manufacture those 8 shot clips fast enough.
The gun does not have any appendages sticking out of either side, so there is nothing to snag on holster or clothing. There is no "safety switch" either. You can take it apart with a dime as a tool, or the edge of an expended brass casing. Beretta cautions against using ammo lighter than 124 gr, which can cause a "failure to eject" (FTE). I shoot 147 gr and had only only 2 or 3 FTE, all due to my limp wristing. (I hadn't shot any weapons in 30 years and I needed to strengthen my two hand grip.)
Glock 26's can FTE if limp wristed as well, as several videos on youtube show.
