I love pocket guns, and small single stack 9mm. I carried the LC9 for many years, later when the LC9S came out, that was my go to winter carry. Nice gun, reliable, nice size. After 4 lcp's, I bought a Pico and never looked back. Actually bought two of them. I am a range rat and spend a ton on ammo and the Rugers got plenty of workouts each week. For a very long time, I have been researching for a new single stack 9mm. A lot of nice one's out there. I shot as many as I could from range buddies, rented a number of them etc. After shooting about 5,000 rounds through the two Pico's, I had to try the Beretta Nano. Well, have to say that I feel in love with it. I have had 4 sessions with it so far and a totally reliable pistol. My last session, was Sunday, On Sat. I had put about 200 rds of mixed ammo, everything from Bulk range ammo, to other other the counter stuff. 115g, 124 gr,147.Totally flawless. I came home on Sat. and purposely did not clean the gun. Sunday was again 200 rds. flawless.
The good part was the fact that this is a gun that is very mild to shoot. Much less muzzle flip than I was use to. It is fast to target and accurate.And so easy on the hand.
I shot, Freedom Munitions, Lax Ammo, Perfecta 115gr. Remington bucket range ammo, Tula Brass Max 115, PrecisionOne 124gr. Plus P, ARX plus P, American Eagle 124 gr. and a few others.
I love the size of this small Pistol.
The point of my post is to spend some time researching your carry. EDC is like buying a great hiking Boot. Each will have one that is perfect for him. The Shield, Kahr, Ruger, Smith, Springfied and on and on all make great guns.
When you find one that is perfect for you, then all is well. The Pico, Nano and Ruger LCR9mm are my personal choices. Other's will have theirs, and that is fine and the way it should be.
To the Op, best of luck.
