Browning-Petter system

from Wikipedia, the free encyclopedia

The Browning-Petter - lock system , also Browning-FN system , for firearms is structurally very similar to the systems:

functionality

French patent 1935 of the Petter pistol
Browning-Petter system ( ČZ 75 )

With the Browning-Petter locking system, similar to the Browning system , the slide and barrel run briefly backwards together on the so-called underlay section after the shot has been fired. The older Browning system uses an articulated chain link to unlock the Colt M1911 . From 1935, the FN Browning HP used a control link below the chamber for the first time; this was later also used in the Browning-Petter system in a closed form. After a few millimeters of reverse travel, the barrel is pulled down in the original Browning system by the chain link, in the FN and SIG pistols by the control link and released from the breech.

With the SIG-210 pistol and its predecessors, including the Petter pistol, the barrel and slide are positively connected by two locking elements - or the "locking comb" - above the chamber in the corresponding cutouts in the slide. Starting with the SIG P220 or Walther P88 model , the Browning-Petter-SIG system is used, in which the barrel only locks through its cuboid chamber with a very precisely designed locking shoulder in the slide at the front and at the rear with a mostly relatively wide nose in the bumper . This type of locking is much more " CNC- friendly".

history

The Swiss engineer Charles Petter , who worked for the French company SACM (Société Alsacienne de Constructions Mécaniques), developed a patented pistol model there in 1934, which was introduced to the French army in 1937 as the Pistolet automatique modèle in 1935 . For the first time the o. A. modified Browning system used.

As early as 1937, the Schweizerische Industrie-Gesellschaft (SIG) acquired a license from SACM for the Petter patents and began developing an army pistol. From the beginning of 1944 the Swiss army and police pistol P49 emerged from the test models SIG SP 44/8, -44/15 and 44/16, which is better known today by its civilian type designation SIG P210 . This also uses the Browning-Petter system.
