Firearm, in particular handgun, and method of producing a firearm
A firearm, in particular handgun, has a barrel mechanism with a barrel and a chamber, a closing mechanism with a slide and also a cylinder-piston mechanism for gas pressure-operated closure delay. The cylinder-piston mechanism has a hollow cylinder with a hollow cylinder wall. A channel is formed between the barrel mechanism and the cylinder-piston mechanism. The hollow cylinder wall is fitted with at least one reinforcing element. The firearm may be produced by the following process steps: introduction of a first portion of the bore into the basic body up to the recess; introduction of a second portion of the bore up to the hollow cylinder; drilling of the channel, wherein the drill is conducted through the bore; and introduction of the reinforcing element into the recess, wherein the bore is closed in a gas-tight manner.
1. A firearm, comprising:
a barrel mechanism with a barrel and a chamber;
a closing mechanism with a slide and a cylinder piston mechanism for gas pressure operated closure delay, said cylinder piston mechanism including a hollow cylinder with a hollow cylinder wall;
a channel formed between said barrel mechanism and said cylinder piston mechanism; and
a substantially rectangular plate inserted in said hollow cylinder wall of said hollow cylinder, said substantially rectangular plate forming a reinforcing element.
2. The firearm according to claim 1 , wherein said barrel has a barrel wall.
3. The firearm according to claim 2 , wherein said channel includes a first channel opening formed in said hollow cylinder wall and a second channel opening formed in said barrel wall.
4. The firearm according to claim 1 , wherein said reinforcing element is disposed in a recess formed in said hollow cylinder wall.
5. The firearm according to claim 1 , wherein said reinforcing element is housed below a surface of said hollow cylinder wall.
6. The firearm according to claim 5 , wherein said reinforcing element is disposed between 0.5 and 1 mm below the surface of said hollow cylinder wall.
7. The firearm according to claim 1 , wherein said reinforcing element is made of sintered carbide or of ceramic.
8. The firearm according to claim 1 , wherein said channel includes a channel opening formed in said hollow cylinder wall and said reinforcing element is disposed in said hollow cylinder opposite from said channel opening.
9. The firearm according to claim 1 , wherein said channel includes a channel opening formed in said hollow cylinder wall and said hollow cylinder wall is formed with a bore opposite said channel opening, said bore having a first portion and a second portion, a recess formed between said first portion and said second portion, and said reinforcing element being housed in said recess.
10. The firearm according to claim 1 , wherein said hollow cylinder comprises at least a first portion and a second portion along a longitudinal direction thereof, said first portion having a smaller diameter than said second portion, and a piston of said cylinder piston mechanism being formed with at least one circumferential groove.
11. The firearm according to claim 1 configured as a handgun.
12. A method of producing a firearm, the method comprising the following steps:
providing a firearm according to claim 1 with a recess, a hollow cylinder, and a barrel mechanism with a chamber;
introducing a first portion of a bore into the firearm up to the recess;
introducing a second portion of the bore up to the hollow cylinder;
drilling a channel to connect the hollow cylinder with the chamber of a barrel mechanism and thereby guiding a boring drill through the bore; and
introducing a reinforcing element into the recess to thereby close the bore in a gas tight manner.
13. The method according to claim 12 , which comprises forming the first portion of the bore into the hollow cylinder wall.
14. The method according to claim 12 , wherein the reinforcing element is a substantially rectangular plate.
15. A firearm, comprising:
a barrel mechanism with a barrel and a chamber;
a closing mechanism with a slide and a cylinder piston mechanism for gas pressure operated closure delay, said cylinder piston mechanism including a hollow cylinder with a hollow cylinder wall;
a channel formed between said barrel mechanism and said cylinder-piston mechanism, said channel including a channel opening formed in said hollow cylinder wall and said hollow cylinder wall being formed with a bore opposite said channel opening, said bore having a first portion and a second portion, and a recess formed between said first portion and said second portion; and
a reinforcing element disposed in said recess formed in said hollow cylinder wall between said said first portion and said second portion.
16. The firearm according to claim 15 , wherein said reinforcing element is a substantially rectangular plate inserted in said recess.
