Wife got the Nano recently, fun gun once you find what it will shoot reliably. I have a bunch of federal champion and several other 'inexpensive' 9mm 115gn fmj ammo that it won't fire a full magazine without a FTE. Hers really likes UMC for what ever reason. Not one hiccup with that ammo in 500 rounds. We tried a bunch of personal defense ammo, 115, 124, 137 in 3-4 different flavors without any issues as well. We just know not to shoot federal through it so easy enough.
I have fairly large hands so my pinky isn't even on the magazine but it is completely manageable to keep on target with minimal muzzle flip.
The size is great, really close to a Kahr PM9 in all aspects.
The take down is really easy and quick and I don't mind having to use a 'tool' (penny, spent case, magazine lip) to do it.
Trigger is just getting broken in bit and getting even better.
Ruger SR-22, Browning Buckmark Camper URX, Sig P250 2Sum 9mm, Beretta Nano, Winchester 101 Trap, CZ 512 Mossberg 500 Flex, Carbine MForgery, and soon a rifle length MForgery........and counting. Damn this is fun
