The Bergmann-Bayard was one of the more successful early automatic pistols, along with the better-known C96 “Broomhandle” Mauser. Chambered in a potent 9x23mm cartridge, several thousand were sold to the Spanish and Danish governments (in Denmark, it was a standard issue sidearm until 1946).

For a bit more history on the weapon, I suggest the review by Guns & Ammo magazine.






I really appreciate these videos and this website. I’ve always been fascinated by firearms, particularly those more antiquainted (yet elegant in their own right, I think) by today’s standards. I really enjoyed these videos and I’m enjoying this site so far. Thanks.
Very informative website indeed. But please do extra care for the firearm
terms. “Main Spring” is the part to give the necessary power for İmpact
Elements like Hammer, Striker, Etc., and not the part to give power for
Breechbolt to keep its place and return thereat after baçkward travel.
Hallo over there.
Really nice site and work your doing. I love the pistol too, as it was eksactly the type my grandfather stole from the germans, hidden between 2 wooden beerboxes. He had deliveret beer to the place were the luftwaffesoldiers was staying. The germans had token a lot of weapons from the danish military in 1943, an the NCO,s got thise M10/21.
Here in Denmark its very difficult to get permission to have an automatic pistol. Strangly enought this type is only ekseption, as i still got the pistol along with hylster, german belt, spare magasine and a nice family story to tell.
Sorry for my english

Hi there,
the Bergmann-Bayard is my favourite of the early semiauto pistols too. But I wonder why they have placed the magazine in front of the trigger.
There are three reasons mentioned in the manual: a better balance of the gun, it allows to use an easier firing mechanism and as a magazine in the grip
determines the size of the cartidge they could chose a bigger caliber if they place it outside the grip.
Are there some more reasons?

I have one that the sear is worn, so with one pull of the trigger it goes into full auto
