38) The P64’s trigger and trigger bar (A) have different springs (B) share the same spring (C) the trigger bar is not under a spring load it “floats”.

39) During double action FIRE the notch in the hammer is engaged with the notch in the trigger bar. Trigger release occurs when the sear is loaded (pushed forward, spring compressed) (A) to the same amount as single action (B) when the sear is loaded considerably more than single action(C) when the rotating hammer is driven out of the trigger bar notch by the land on the hammer directly behind the trigger bar notch on the hammer (D) when the hammer sear land is engaged with the sear

40) The height of the trigger bar at INITIAL double action pull, resistance felt, is maintained by (A) The large land area on the hammer (B) the disconnector (C) the safety barrel (D) trigger spring

41) The horizontal movement of the trigger bar, undesired, (forward; backwards; up and down desired) is limited by (A) the trigger spring and the pin upon which it rests (B) lands in the slide (C) the hammer strut.

54) The hole in the left side of the frame below the safety can be used for (A) tool kit storage (B) magazine function check (C) trigger bar to sear engagement (D) The hole is only to lighten the frame

55) How does the pistol fire in double action when the trigger bar engages the sear from almost the start of the trigger pull? (A) The trigger bar rolls off a cam land on the hammer behind double action engagement notch and then the hammer is released. (B) The sear releases the hammer the same as in single action. (C) The trigger bar holds the sear off the hammer’s cam for single action hammer notch engagement and stays off the cam of the hammer and away from the single action notch of the hammer.

56) What are some explanations for the harder trigger pull at the end of double action fire (“The Hump”) A) The sear spring almost goes to coil bind where as in single action it is compressed and then released to a great extent maintaining only a little spring pressure for trigger bar and sear engagement (the famous light single action trigger pull.( B) They had a cargo container of springs in the warehouse that nobody knew what they were for and somebody said, “use those on the trigger bar.” C) High rate # hammer spring to start with. D) Only a triangular hammer does that. E)

57) During the production history of the P64 “The Unofficial P-64 Resource” and its members have noticed some parts are different. Which ONE part has NOT yet been noted as there are two types?

59) When the red dot is covered by lever arm rotation on the slide (A) The trigger bar is fully lowered and the trigger will express its full range of movement with no resulting action (B)The pistol can now be carried “cocked and locked” (C)The hammer can still be pulled back all the way to the frame. If you think yes here, DO NOT DO THIS WITH A LOADED PISTOL. (D) The safety barrel rotates to limit the firing pin travel and the height of the exposed pin.

60) Searching the blogoshere, I read where somebody got tired of hearing about the .380 acp in a 9x18 makarov caliber pistol “controversy” and took his VZ-82 and shot it 300 times in a row with .380 and then without stopping for nothing, 100 times with 9X18 Makarov and then 100 times again with 9x18 Makarov. So, its O.K. right?

(B) Loaded chamber indicator and firing pin (C) Trigger and trigger bar (D) Disconnector and sear.

62) What is a good explanation for the P-64 having a “U” shaped pin end for the trigger.
A) Because if It did not it would come out one side or the other and possibly interfere with the slide functioning and more. B) This design incorporates tighter tolerances. (C) Most all the other parts are a slip fit and do not require the use of hammers and punches, so to keep the assembly theme going the designer used this pin style.

3) FROM TIME WORLD Sunday May, 22 2011

There is an arms selling frenzy," says Abu Rida, "and it's all going to Syria. All of it." He added that weapons also are flowing into Syria from Iraq. The most sought after weapons are assault rifles — the ubiquitous AK-47, and variants of the M-16. A good quality Russian Kalashnikov, known in the Lebanese trade as a "Circle 11" from the imprint stamped on its metalwork, today fetches $1,600 — a $400 increase from a month ago. In 2006, the same weapon only cost around $500 or $600 FROM TIME WORLD Sunday May, 22 2011

handle the pistol in the appropriate manner.

5) Considering double action and single action firing and the trigger bar to sear engagement, what is different between the two?
