The present invention is a species of my invention dis 15
closed in my Patent No. 2,899,767.
It is an »object of the present invention to provide a
pistol capable of firing cartridges of heavy caliber with
a minimum of muzzle Iift and one capable of firing a
large number of shots in succession.
This is accomplished according to the present inven
tion by providing a pistol in which the barrel thereof,
which is a blow forward type cooperating with an aligned
fixed breechblock, is located on the lower part of the
frame so that the axis of the barrel passes through the
grip in the same manner as disclosed in said Patent No.
2,899,767. Thus, even when firing a heavy caliber car<
tridge, the tendency for muzzle lift is substantially reduced.

magazine for carrying heavy caliber cartridges which
can be readily inserted and removed from the pistol and
which provides a maximum capacity. Preferably the
magazine is so arranged as to lie above and parallel
with the barrel providing the proper balance for the gun.
A feature of the invention resides in the magazine hav
ing a large capacity and which can be readily iilled with
cartridges and, when put in position on the pistol, re
leases the cartridges to be fed into the guide means on the
breechblock to be fired successively.
Another object of the invention is to provide a novel
sight structure for the pistol which can be easily and
quickly instalied in the top of the pistol frame and can
be readily adjusted to correct for windage and elevation.
Other features and advantages of the invention wiil be
apparent from the specification and claims when con
sidered in connection with the accompanying drawings in
which:
FIG. 34 is an end view of said detent.
As shown in the drawings, the pistol comprises a frame
10 consisting of a grip portion 11 having a trigger
guard 12 integral therewith, a barrel-receiving portion
13 adapted to be secured to the grip portion and a maga
zine-receiving portion or member 14, as shown in FIG. 9.
When these portions are assembled by inserting the
end 111 of frame 11 into socket 131 on frame 13 and
are locked in place by the interlocked portions of frame
portions 13 and member 14 secured to frame 11 by
boits 112, as shown in FIG. 1, the barrel-receiving por
tion 13 is located on the lower part of the frame so that
its axis is immediateiy above a trigger 16 disposed with
in the trigger guard and has a barrel 15 slidably mounted
therein. The axis of the barrel, when extended, passes
through the grip intermediate the ends of the grip. The
grip has the usual side ñakes 17 `and is provided with
a gripping surface 17a adjacent the trigger guard which
forms an angle t), preferably of 38°, with the axis of

56 is mounted in the closure for rotatably supporting a
cartridge carrier 57 at that end. A fixed pivot pin 58 is
striking direction. Referring to FIGS. l, 20` and 2l, the
striker is provided with a projecting sear 36 passing
through a slot 33a in the housing in position to be en
gaged by the end 37a of a sear link 37, pivotally mounted
on depending ñanges 33b on the housing, and being held
thereby in cocked or retracted position. The other end
of the sear link has a shoulder 38 which cooperates with
an actuating member 39 on the trigger so that when the
trigger is depressed it causes the sear link to rotate about
the pivot to release the sear and permit the striker under
the urge of the spring 35 to move forward and strike
the firing pin driving it against the action of the spring
32 into firing contact with the base of the cartridge to
fire the same.
As shown in FIGS. 1 to 3 and 16 to 19, the barrel has
a rear extension 40 formed by a pair of side rails 41
mounted in a closure 59 for the forward end of the cas
ing and projects into an axial bore 60 in the cartridge car
rier. The cartridge carrier is provided with longitudinal
flutes 61 which are adapted to support a plurality of
45
cartridges ‘26 in end-to~end relation in each of the flutes
for sequential feeding to the barrel.
In order to feed the cartridges, the casing is provided
on its inner surface with a spiral feeding cam 62 adapted
to be positioned between each of the cartridges in the
flutes.
As the carrier is rotated with respect to the cas
