4. Be sure that prior to any imminent action all magazines are on full tension at 60 pounds.  If your magazines have been in use a long time, it is wise to pull out a few rounds before loading, but be sure you still have on the full tension.  This precaution will give the last few rounds in your magazine an extra push and will prevent jamming.

 

5. Practice all operations, especially cocking and loading, in the dark or with your eyes closed.  This type of practice, blind cocking and blind loading is invaluable.  A PT operates chiefly at night and any kind of illumination of deck is taboo.  Get the feel of the gun, the magazine, their every part and get the rhythm in cocking, loading, and firing.

 

30-Cal. Cockpit Gun:  The pea shooter is a very light gun carrying a great amount of tracer ammunition.  This gun may be operated by an officer or gunner on the bridge.  It is very much like a 50-Cal gun in looks and operation.  It can have a single or double barrel operation.
