Beretta BU-9 Nano Pistol

The Beretta BU-9 Nano pistol has been officially announced by Beretta. The 9mm sub-compact carry pistol will go on sale in late October.

The most interesting feature of this gun is that the serial number is not attached to the polymer frame. The serial is attached to an inner steel chassis. In the future, owners of the Nano will be able to purchase aftermarket frames without having to worry about FFL transfers.

The Nano has no external safety (it does not a Glock-style trigger ‘safety’) but does have a striker deactivator, allowing the gun to be decocked before disassembly without having to pull the trigger.

The serialized steel chassis.

The pistol has the sleek Beretta Strom look. Its frame has no protruding levers or buttons for a snag-free draw. The slide has a ProNox black nitride finish and user removable/adjustable sights.

  • Looks like a flattened PX4 Storm. I would like to hold it and shoot it. The PX4 Storm never really felt comfortable in my hand.

  • james

    a cross between a Sig and an XD..

  • Pat RSTLNE

    Beretta does it again. I’m sure this will be the most well designed well made pocket pistol available for sale anywhere.

  • Looks Exactly like the FCU (Fire Control Unit) in the Sig P250 which has the same ability and you can buy the P250 in a 2sum where you get a subcompact and a full size frame for just a little more. Only advantage I see to the Nano is its Striker fired instead of DAO like the 250.

    I don’t think I like the fact that it doesn’t have a slide lock. I get that it has a specific job of being a conceal carry weapon, but I don’t want to have to rack all of the ammo out of my magazine to get the gun to lock back.

  • Lance

    Looks like a nice back up to my M-92FS and I like the fact it has no BIG buttons or trigger safties to make it a very simple design. I like to buy one…. If you can afford one.

  • SpudGun

    Beretta have obviously spent all of their Nano money on developing the pistol instead of marketing as the accompanying video was beyond cheap, I have seen more expensively produced amateur gun videos on You Tube.

    The video was useful in graphically describing the ‘trade off’ between flushness and protruding levers. Get rid of the protruding levers and you’re gonna need a box of tiny wrenches to disassemble the pistol. Not a big deal if you carry a multi-tool wherever you go, but still inconvenient.

    I do like the serial number on the internal chassis so you can buy different frames and barrels to make the pistol modular. Maybe some engineering genius can come up with a new frame that allows the levers to all sit flush when holstered and then pop out once the trigger is pulled, so you have the best of both worlds.

  • cy

    I would like to hold one. I’m searching for a new carry gun, this adds to the short list.

  • Slim934

    Holy smokes it’s even skinnier than the keltec P11.

    This could make a very interesting buy.

  • Pete Sheppard

    The metal serial-numbered “frame” inside a replaceable polymer grip was pioneered by Kel-Tec for the P11 back in the ’90s. That’s not a knock on Beretta, just noting that they adapted a successful concept for their pistol.
    It’s also worth noting that the pistol is larger and heavier than the Kel-Tec’s PF9, yet hold one round less.
    Is the dimple forward of the trigger intended to function as a light/laser rail? If so, it’s much more attractive than the standard Picatenny-type mounting.

  • Robert

    Is the Beretta Strom in memory of Strom Thurman?

  • interesting, nice lines and size wise comparable to others in its class. Am I just not seeing a slide lock on it, or is it lacking one? Does the slide lock back on an empty mag?

  • Kush_Slayer

    What exactly is the point of the striker deactivator? One of the reasons he says for having it is so that you don’t have to pull the trigger for disassembly, what is wrong with just removing the magazine, checking the chamber, then pulling the trigger, also he states it can be used as a safety that you can have on it at home, yet there doesn’t appear to be a striker reactivator besides pulling back the slide again, which brings me back to the question of why not just check the chamber every time you are going to use it.

  • Jesse

    The striker deactivator decocks the gun but can the trigger then be pulled to fire it again? If you can’t then it’s really only for disassembly and it doesn’t really make it any safer to carry.

  • crosswiredmind

    I love that it was designed for .40 as its native caliber. Should make the 9mm version a solid gun.

  • Sandwichy

    Yeah, the barrel looks like it sits a little high. I’ll wait until the .40 to get excited about this one.

  • skipsul

    Looks like they borrowed Sig’s idea RE the serial numbered frame. Glock take noe.

  • I’m excited about this little Beretta Nano. The fact that it was designed as a .40 SW caliber pistol and then introduced in 9mm is a big plus. If shoots a well as my Beretta Storm I will be more than pleased. The Nano is on my “Buy” list.

    I am a disappointed owner of a Kimber Solo Carry. Beautiful little pistol but after two returns to the factory I still don’t trust it.

    Also own a Kel Tec PF9, Ruger LC9, and S&W CS9

  • Hrachya Hayrapetyan

    I heard that American shooters prefer lever (button) style slide release …am I right?

  • jdun1911

    Really don’t like the idea needing a tool to field strip the pistol or the idea of disabling the gun. I’ll stick with the Kahr CW9.

  • DaveP.

    If the Beretta ” …does not a Glock-style trigger ‘safety'”, then what’s that little thing on the front of the trigger?

  • JT

    At the end does he go to press where the slide stop would be? He looks like he hesitates for a second and he’s thumbing for the stop, but it’s not there lol

    Makes sense though. It’s what I would instinctively do.

  • ec

    if it “does not a Glock-style trigger ‘safety'” as you mention in the review, then what is the lever on the trigger in the photo you provided?

  • tomaso

    I have a Walther PPS 9mm and it only shoots well for me with the largest backstrap…the small backstrap aligns my trigger finger too far onto the trigger…this design looks to have the same issue…changable backstraps can be a hassle ( i had to pin mine on the PPS) but it is the best way to adjust the LOP (length of pull)..i do like the fact theirs no slide release..i also realy like the interchangable bodys…possibly were the diferent grips will be offered…and a great price.

  • Slim934

    I really like the whole notion of Sights than can be very easily changed by the end user.

    How STURDY these sights are is another question, but I am happy to see some slight innovation in this area.

  • Ben Branam

    Kind of looks like the way Kel-Tec has been making weapons for at least 10 years.

    • KM

      As an unHappy p3at owner, I would not compare Kel-Tec to anything of remote quality, even in aesthetics

  • strongarm

    I have not seen or handle this pistol, but seen its manual on
    Beretta USA site.

    As understood from Parts Diagram, Nano had a very serious
    defect on Sear Passificition system…

    Should pistol gets an impact or dropped to the left side, the
    sear is prone to slide sidewardly through inertia as going to
    uncocked position and disarming the user.

    I hope I were wrong.

  • strongarm

    Dislikes show that l could not explain the situation clearly…

    Beretta USA has Nano User Manual at website. “Please Read The
    Manual First Before Using”… No need to handle the gun…

    Photos speak lauder than words… Please go to Page 40 and fınd
    the photo at bottom right… This shows the connection and lay
    out of Cocking Lever with all other parts in place in inner receiver
    and reveals the way of Striker Deactivation via sideward release
    of Cocking Lever by push of Deactivator Pin. Parts Diagram at end
    of Manual also corrects it.

    The Cocking Lever is free to move to left. There is no mechanical
    obstacle provided to stop it… Only a spring with force to overcome
    by push of a ball point pen. The spring is double purposed…Either
    to push the Cocking Lever forward, or to push it to right against to
    Deactivatior Pin…The Slide, in assambled form, has neither an
    obstacle for Cocking Lever leftward slide since Striker Deactivation
    would need manual retraction of the same before to start.

    It seems that Design Team had sacrificed the Security of Cocked
    Striker untill intentional trigger release for the sake of so called
    innovation of “No need to pull the trigger before Field Strip”…

    There would be no need to try to fınd something to push the Striker
    Deactivator Pin, since only putting the gun with a light slap over a
    semi hard object like a book would be enough to decock the gun…

    This leads more serious happenings in real life, since an impact or
    drop would take the gun to uncocked mode without aware of owner.

    Beretta should thank for revealing, since no gun has sold, up to that
    time to bring a lot of headache in the future.
