Ruger Double Action Revolvers Quiz!

I am semi-retired and I am taking a self-passed and self-taught Armorers course and now I am on the Ruger Double Action Revolvers. I hope to become a part-time light Gunsmith in the near future.

There are over 60 quiz questions covering this firearm and I have answered most of them hopefully correctly but during my study and research I am having some problems related to some of the following quiz questions. I have conflicting answers.

Can you help me determine the correct answers for these few quiz questions? Please correct my wrong answers!

Thanks for your help.

Note #17. The revolver could fire without the transfer bar by simply pulling the trigger. True or false

Note #18. The spring and plunger for the cylinder stop (cylinder latch) spring loads the cylinder stop (cylinder latch)
a) up
b) down

Note #19. The crane has two balls that retain the cylinder. True or false

Note #20. The center pin system utilizes a
a) right hand thread
b) left hand thread

Note #21. The trigger is also the sear. True or false

Note #22. The hand (pawl) is not spring loaded. True or false

Note #23. The cylinder must go into the frame before the trigger guard assembly. True or false

Note #24. What is the slave pin that is supplied by Ruger used for?
a) To captivate the mainspring
b) To install the trigger
c) To take off the front sight

I can only answer 1 (hangs head in shame). You are correct on #17 a Ruger that has a transfer bar will not fire without it. No way no how.

18: Since the latch/stop is located in the bottom of the frame opening it obviously has to be spring loaded upwards to latch. That and the fact that when the trigger is pulled back in DA mode on my Ruger revolvers I feel and hear the catch being released and snapping up into the locking position just a little before the hammer is released.

22: The hand must be spring loaded on any revolver or it will not be able to snap over the ratchet teeth of the cylinder to become ready for the next indexing of the cylinder. OK, I supposed a fancy full control cam system COULD be used instead of a spring where the hand was under full mechanical control all the time. But I've yet to see a revolver that uses such a complex arrangement.

The rest, other than the ones you've already answered, I'm not sure about since I've not taken any of my Rugers apart to that extent.

Note #18. The spring and plunger for the cylinder stop (cylinder latch) spring loads the cylinder stop (cylinder latch)
a) up it's a cute cam action pushing it upwards to lock in the slot.
b) down

Note #21. The trigger is also the sear. True or false

Note #22. The hand (pawl) is not spring loaded. True or false

Note #23. The cylinder must go into the frame before the trigger guard assembly. True or false

Note #19. The crane has two balls that retain the cylinder. True or false

i have never seen any balls in a Redhawk?

 

[Deaf Smith]

They must mean indent balls and not ball bearings.

i still don't see any balls......i have looked at my manual too which is what you posted....

The Brownell's schematic for the GP100 shows 2 balls.

Personally, I always thought the stub grip frame of the GP100/Super Redhawk and Dan Wesson revolvers was funny/stupid looking.
Now owning a DW and a GP100 (felt no need to buy a SRH after getting a RH) I see how comfortable the grips are and how much latitude they give you in grip design.

They may look funny, but they work well and feel great.

17 False - the hammer won't contact the firing pin without the transfer bar being installed and raised. This is a safety feature to prevent firing if the hammer is struck, as in a dropped revolver.

18 up

19 true

20 B

21 true

22 false

23 true

24 Slave Pin ????

 

[ghitch75]

i still don't see how 19 could be true when not all DA Rugers have balls.....

 

[Jaymo]

I thought the hammer dog functioned as your DA sear and the SA notch in the hammer acted as your SA sear.

I wondered how come the OP only posted questions 17 on up, so I googled "Hoppy70" and he has every gun & firearm blog lit up with the same exact questions on here!!
