DISASSEMBLY INSTRUCTIONS AND REPAIR PROCEDURES FOR MODEL V-300 PISTOL
Preliminary to disassembling this gun, check the three Frame Screws, 300-54 to insure that they have not become loose while the gun was being
used and that the halves of the Frame are drawn tightly together. This procedure often corrects minor malfunctions such as improper feeding of the
BB's and minor cocking problems. If the threads are stripped in the casting replace the self tapping screws with 180-12 Hold Down Screws.
If the malfunction persists after trying the above, disassemble the gun as follows:
1. Remove Grip Screw, 600-53, and Grips 600-48 and 300-43.
2. Remove two Rear Sight Screws 300-35.
3. Remove four Frame Screws 300-54.
4. Remove R. H. Frame 300-2.
This exposes the Sear 300-10, Sear Spring 140-27, Trigger 300-11, Safety 300-17, Safety Spring 300-33A, Lever Assembly 300-50, Lever Retainer
Spring 300-36 and the Barrel and Tube Assembly. If the Sear, Trigger and Lever mechanism appear satisfactory, it will not be necessary to remove
these parts and only the Tube and Barrel section need be removed as follows:
1. Remove Sear Spring 140-27, lower Sear, Lift out Tube and Barrel Assembly. (NOTE: Remove Ball 105-39 and Ball Spring 350-17 which
are used to retain BB).
To disassemble Tube and Barrel Assembly proceed as follows:
1. Apply pressure on End Plug 300-22 and push out End Plug Pin 300-24 with an undersize pin. (NOTE: End Plug is under heavy spring
pressure and extreme care must be used in releasing the End Plug Pin and End Plug).
2. Remove End Plug 300-22 and Plunger Spring 300-23.
3. Check movement of Hammer Sleeve Assembly 300-47 in Tube 350-3. The Hammer Sleeve should move freely and not bind until a point
of resistance is reached where compression begins. This operation can be done by moving the Hammer Sleeve by hand, using the tong
on the Hammer Sleeve.
4. While moving the Hammer Sleeve by hand, with the tong, check the action of the Pop Valve 300-6 by looking into the BB entry hole. The
end of the Pop Valve should appear in the BB hole after the pressure reaches a certain point. This is an indication that the Pop Valve
Assembly is working properly and no further disassembly is necessary.
If the stem of the Pop valve fails to appear, the condition of the Teflon Ring 350-14A on the Hammer Sleeve Assembly 300-47 should be checked
for scratches or nicks. If the Teflon Ring is Defective, the Hammer Sleeve Assembly should be replaced and the POP Valve Assembly tested again
as above.
