I really like the Nano, as it feels like a “full size pistol” when shooting hundreds of rounds in one session. Well built frame, robust structure, practical sights, nice ergonomics, and I’m actually OK with the trigger which feels like a true DA trigger. I was excited from the very beginning. And I shoot it well and accuratly out to 25 yrds. At the range, however, the excitement shrunk dramatically, when I experienced several FTEject problems with the usual bulk 115gr ammo as well as quality 115gr ammo. That was after 400 rounds. Back at the desk I did a little research and dug through a lot of internet pages including the Beretta forum, and I learned that I am not alone. Many Berettians suggested to mind the 'usual break in' procedure without telling with how many rounds a break in period was supposed to remedy the problem. More strikingly, the conventional wisdom was - well supported by a Beretta rep - that the Nano requires quality ammo, preferably 124gr ammo or heavier. OK, since I really like that thing, I’m putting up with that shaky argument and order 400 rounds 124gr ammo of different brands. Boohooo. At the range I realized that the 124gr ammo was more reliable but I still had way too many FTFs to be a happy camper. So I contacted Beretta CS and I got a reply within 48 hours. The communication was conducted professionally and no nonsense excuses were given. I got a call tag, UPS picked it up, and off the Nano went to the Beretta shop. After 9 days it came back with the comment: “ Replaced extractor and extractor spring. Polished chamber. Oiled and test fired 30rds of Win 115gr FMJ ammunition with no malfunctions.” (Hmmm…why test fire it with Win 115gr ammo when it had been suggested that only 124gr and heavier would work. ) I put it to the test in two shooting sessions, 400 round each, with all kinds of ammo. During the first session I had 2 malfunctions, one with 147gr Win and one with crappy under-powdered Federal Wally stuff. During the second session, I had 0 malfuctions, running Gold Dots on the higher end and FMJ Win White box and stuff like brass Monarch on the lower end. I don’t know what the future brings for my very pistol. The testing/practising will go on, but for now my confidence in the Nano is restored and I have no hesitation packing it. And Kudos for Beretta CS, thank you Beretta Customer Servise!
