A shot is fired. The gases
expanding forces the bullet
out of the barrel a small part
passes through the gas port as
soon as it is uncovered enters
the gas cylinder and by a sudden
blow forces the piston and slide
to the rear.
The compresson of the recoil
spring commences with the
first motion of the slide
the slide is secured through
the Hammer Pin Link & Link pin
to the bolt lock as the slide
moves backward the top of the
Link roll downward and moves
slowly back ward draws the
bolt slowly to the rear and
gradually starts the cartridge
from the chamber.
so the lock links and incline
surface on its underside comes
in contact with a vertical
Tang on the firing pin with
drawing the latter. The bolt
is now entirely below
the recoil shoulder
and free to move to the rear which
it does with the speed of the
slide carrying the bolt with
it

The extractor claw grouping

the rim of the cartridge drew
it completely from the chamber
carrying it backward where,
striking the ejector it pivots
around the extractor until
brought against the rear
edge of the ejector opening
when it hits the extractor
and flies out to the right
front.
The slide continues its
backward motion until
stopped by the buffer,
when the seor engages the
seor notch and
prevents its return forward.

2nd phase

Returned the piston and slide
to the firing position, Not in
power recoil spring.
1 Intorduction of cartridge
2 Locking
3 Strikeing
The trigger is pulled
and the piston and slide start
forward under the pressure
of the recoil spring carrying
with them the bolt bolt
Lock, Link, Hammer & firing
pin
The lip on the lower surface
of the bolt encounters the
Rim of the next cartridge
Presenetd by the magazine
and strip it out of the magazine.The bullet strikes the
inclined surface on the rear
of Barrel and is guided into
the chamber. As the cartridge
is pushed from the magazine
it is raised vertically by
the follower when opposite
the wider opening between
the magazine ears, and
sliders under the claw of
the extractor.
The lock in its lower
position has no tendency to
raise against the top of the
receiver as the link pin is
lower than a line drawn
from the bold lock pin to
the hammer pin. However
the cammed surface of the
bolt are now brought against
the bolt supports, the bolt
lock is forced to rise and
the link pin is rolled above
center. The upward movement
of the lock causes it to
decrease its speed so that
bolt seats the cartridge
slowly into the chamber.
The slide continues its
forward causing the
bolt to rise furthur now
under the rolling action
alone until completely
locked against the recoil
shoulders. The slide in still
moving ahead brings the
hammer against the firing
pin and primes the cartridge
almost simultaneously
the shoulders of the slide
meet the abutment of the gas
cylinder tube and slider
motion is arrested.
