Command Arms Accessories’ Glock Shot Counter

Command Arms Accessories has introduced a shot counter for Glock users. The shot counter counts split times, as well as total round count for maintenance. From’s KitUp!:

Command Arms Accessories USA is now offering a high-tech shot counter for several Glock pistol models.

The Secubit Gun Shot Counter is the “ultimate upgrade for shooters who want to improve split time (time between shots), increase shooting accuracy, and keep a full record of shot count for maintenance,” according to CAA’s website.

“The GSC is smallest counting and recording device available—small enough to fit into the grip pocket of a Glock … while preserving grip ergonomics and carrying comfort.”


The GSC detects number of shots fired by sensing vibration and shock and will record up to 500,000 shots.
It shows exact date and time, computes time between shots, or split time, and rate of fire to provide you with the necessary data to improve your accuracy, according to CAA’s site.

The GSC fits the Glock 17, 18, 19, 22 and 23 – Gen 1-3.

It retails for $100 and includes advanced software that automatically collects and stores gunfire data, making it available to an Android device or a PC through a USB cable.


The US Army has been working on a shot counter for issue carbines since 2005, at the latest. Whether CAA’s development has been influenced by Army research, or whether Army research will be influenced by the Secubit counter is unclear.

    Could they make this for other guns aswell? That and could they make a counter that’s connected wirelessly allowing you to keep track of rounds in magazine?

    • They already do. They make something that goes on a top picatinny rail.

      I’ve actually been building something like this myself, and my reaction to this article was pretty much “well, sh*t…”

      I’m using and arduino and plan to have shot detection and logging with GPS built in. I’ll also be building a mobile app that allows your phone to send emergency texts with your coordinates, and description when a switch on the device is enabled (bluetooth connection used here). Basically, a carry option that allows 911 communication as soon as you begin dealing with a threat.

      What gun or guns would you want to have this compatible with? I was trying to squeeze my prototype into an XDM grip panel, but a light rail module would allow wider usage.

      I’m not even sure anyone would want one. I’m just bored and tinkering.

      • iksnilol

        That sounds like a great idea. Calling 911 automatically while dealing with the threat.

        The rail mounted version would probably be the best option. More flexible and you can make it more rugged due to not needing to squeeze it in.

        • thetruth

          DUDE Seriously???

          • iksnilol

            What’s so bad about it. Nothing different than having a phone in your pocket, only difference is that you don’t have the distraction of fiddling with a phone.

      • Kevin Harron

        That does indeed sound like a great idea for those that carry.Being able to call 911 without taking hands off your weapon or eyes off the threat sounds like a good idea to keep safe in a high threat situation.

      It seems to me this is just anaccelerometer. You could easily put it in a magpul pistol grip on an AR. Or even tape it to the gun.

      • iksnilol

        I figured that out. What I would be interested in is wiring it to some display so that it shows how many rounds I have fired now (think a videogame HUD).

        • Budogunner

          That is super easy with arduinos. Small led displays are cheap. I even saw a project where someone mounted a tiny display inside an Eotech replica that allowed him to design his own reticle and adjust placement digitally.

          The trick would be detecting magazine changes and resetting accordingly. Maybe NFC tags in the mags? You would have to reset their values in software after each use, but you could even ‘remember’ the rounds left in retained partially spent mags that way.

          • iksnilol

            Never thought about NFC tags, since I am not an engineer I don’t even know what an NFC tag is.

            Could you also display in the optic the number of rounds left in the mag? I wonder why nobody has capitalized on that. You could put the unit with batteries in the pistol grip, possibly add the tags inside the follower and display in the red dot optic.

            Im tech retarded but NFC stands for Near Field Communications (i think) small little “chips” that would communicate with your shot counter. I believe it’s the same tech that allows people to pay with their phone instead of a credit/debit not sure though as I dont pay with my phone vs with a debit card. Again I’m tech retarded and I could have the whole thing back asswards

        • thetruth

          How many freaking rounds are you firing that you loose track of what your doing? You cant wait till the gun goes empty like the rest of the world…what are you preparing for…Someone just watched lone survivor…hahahahaha

    • thetruth

      OMG…We could make a gun that holds 2 oz of soda in the magazines and you idiots would be asking..”Can you get grape soda instead of Dr. Pepper”….”I would buy one then”…”My sheep herder says I must obey and follow in line”

      • iksnilol

        What’s wrong with having a blackbox for your gun? I like keeping track of rounds fired and whatnot. Helps with maintenance.

        You sound awfully paranoid or old fashioned to me.

  • Lt Donn

    Really?…another hi-tech solution to a non-existent your $ and either buy more ammo or hey, I have a really unique idea…how about putting the cost of this unit towards an actual training class!…now there is a fresh idea!

  • sam

    Eh, I try to keep track of shots fired. I’m lukewarm on the practice, not necessarily a problem if not done, but I think it’s a good idea.

  • Core

    Do they make this for a real gun like the 1911?

    • Dan

      Oh snap! #shotsfired

      • thetruth

        don’t worry I got this!

    • thetruth

      Hey old timer….Your gun only holds 7 rounds…can you count that high? Using a 1911 is like saying…”No No No…I don’t want to drive you brand new Ferrari…I’m going to break into the automobile museum and get me a old piece of crap to drive” Because its a REAL CAR!

      And I have no use for your fancy new technology, says the idiot using a computer/internet and brand new technology to post his crappy comments.

      Also where would you put this on your antique?,,,1900’s called they want your museum piece back!
