Francisco Arizmendi

Magazine 6 cartridges, length of the barrel 6,5 cm, breech + barrel 12 cm (only one part), height 8 cm. Approximately 1 cm thickness (it is very flat), 7 stripes (enough deep, it was useful little). The breech, mobile, has a retractable striker maintained in position sunken by a helical spring. A rubber disc in bottom of the carcass is used to damp the breech in its back movement. The extractor is on the right side of the breech. The ejector on the left in the breech. The spring recuperator is placed with the top of the barrel. Astute system which uses the retreat to make move back the breech and this spring to bring back the whole ahead.

The disassembling of breech/barrel is obtained while pressing on the button in front of the carcass. Very simple. One releases the whole to the top then forwards.

The machining of the breech is very precise. Steel appears of good quality. Bronzing was remakes.

A safety prevents the hammer (which strikes the striker when one draws) to fall, including when one rather strongly supports on the trigger. It is in all the ways rather hard. In open position the inscription “Feu” appears on the carcass, which undoubtedly shows that this weapon was planned for the French market.

I find it very near to Pieper to before 14.



I confirm: Boltun: mark used by F. Arizmendi on its pistols semi-auto.


In appendix an assembly presenting on the one hand Boltun 6,35mm, and on the other hand “Dismounting” and the “Tilting” of Nicolas Pieper.

The differences in structure are obvious. Boltun 6,35 is thus not a pure and simple copy of the pistols of Nicolas Pieper.

There is also Boltun in 7,65mm Browning and one in 9 mm Short, copied, him, from the FN Browning 1910.




In top: the Spanish pistol Boltun; in the center, “Dismounting” of Nicolas Pieper; in bottom, the model Nicolas Pieper 1909, known as “Tilting”.
