We really haven't looked into the nano. But there's a A TON OF cool accessories for it, which is always nice.
Dave has the PX4 Storm Subcompact 9mm and likes that, but AZ is the Wild West, you can carry just about anywhere, so he has the S/C on a holster on his belt. Not worried about printing. If he wants to conceal it, he just pulls his shirt out.
It's the only striker fired in the Beretta line up, not hammer fired. On the positive side, it won't get snagged on clothing. But we have no experience with striker fired.
We prefer the long double pull or our Billenniums which can be cocked and locked. We find we're also preferring more metal than polymer.
We shot our friends Ruger LCP (same concept as nano, small 9mm, almost all polymer) and it just about blows your hand off with recoil. Although we haven't shot a nano, the kick is the same from what we've read. If I want kick, I've got my "Lavender Lady" 38 special….now that little sweetheart kicks something fierce, as did my Ruger LCR.
Also shot my friend's Ruger SR9c a while back, super sweet. How's the kick on the 40 Billy? At least the SRs have more mass than the LCP or Nano, so may tame some recoil.
I prefer the Beretta Cheetah series ( model 84, 85, 86 and 87) for home defense or carry. They're .380 (except the 87 which is 22LR) and kick quite a bit because they're a blowback design, but we find they're small enough to conceal, have good mag capacity and will drop somebody if necessary. And the 86 is a tip up, so I don't even have to rack that one, it's hot and ready to go.
But MY fav for small/conceal is my Beretta Titanium Tomcat, .32 ACP. (ALSO a tip-up) It's small, all metal (so yes, it's heavier), but I'm seriously accurate with this little guy even though it's so short, so I figure I can get several 32s in somebody and it'll certainly slow 'em down. And if I hit the mark, they'll get even more than slowed down...
Bottom line, since we hardly ever find the need to truly "conceal", (and I don't conceal, only Dave does…mine would be in purse or a back pack and as they say, if you can't draw and fire within 2 seconds, you may as well just skip it. I'd be digging around my purse for 15-20 seconds, so I'm out!)
We just aren't interested in super small because of the freedom the AZ laws provide us.
Have you checked out prices on Gunbroker.com and GunsAmerica.com? Can usually get a good 98-99% condition for a good discount. I have a standing search on both sites daily for Beretta stuff, and there's a TON of nanos for sale. We've bought guns off both sites, they're reputable. Just make sure the seller has some positive feedback.
I can send pics of the Cheetahs and Tomcat if you're interested in seeing sizes. I have several pics comparing their sizes to a man's hand etc...
