	Vall, From what I can tell the DST lower tang will fit either flat or coil spring actions. Besides the frame itself with the hole for the spring loaded plunger that provides lever tension, the coil spring lever and hammer are only other differences. Interestingly, Ron Smith would install a coil spring on a flat spring hammer and make a different shaped spring to replace the flat spring that provided lever tension only OR like my 25 Hornet, fit a forend hanger with a spring loaded plunger in the end to provide the lever tension.

	I cherish the 'fat' pin you spared me a while back. I knew you were a caring and generous fellow, but didn't realize you'd let me have a scarce item while you yourself needed to revert to patching up a junk item. Jack, here's to you Oh, wait. I just remembered the crosswise pins are different and probably are getting scarcer than good pickup lines

	I have not torn one of these rifles apart and can't see on any diagrams I have how the FP is held in on a C Sharps action. What method is used to positively retain the pin?

But, in a few days I will have a flat spring action, with the wide double set triggers, in my hands. I can check then but looks like Jack has the answer. Bob

	to remove the firing pin, just locate the screw seen on the top of the breech block. that ought to be a snap. find the proper screwdriver to fit. cock the rifle and remove the screw. now, just raise the cocked rifle muzzle up and thud the but down on a firm surface (don't damage it, only a bit of a bump). the pin ought to drop out on the table. put it back in with a touch of lube when finished looking and replace the screw. No bump this time, haha and don't forget to uncock it prior to moving on.

What method is used to positively retain the pin? To remove the pin just take out the screw at the top of the breech block. Then if you pull the hammer all the way back you can get the pin out from the rear of the breech block.

I made a few with the “spur” but found it easier to just turn a round “spur less” firing pin with the correct nose diameter for a small spring. It is an easy task if you have access to a lathe. Jack Without the spur then the hammer must be cocked before dropping the action, correct?

	Putting the hammer at 1/2 cock would not retract the firing pin. It would take the pressure off of it, but the tip could still be protruding enough to hang up and break.

	I've never owned an 1885 that needed me to cock the hammer before lowering the breech block, whether it be an original or a quality reproduction like a CSA, Meacham, or whatever. I have an original that was modified to have a spring like Jack suggests. It also works fine to just lower the breech block like a normal 1885.

	If all else fails you could use the system that works on Ballards which is to supply the firing pin with a slight upward contour on the end that protrudes from the breech block at full extension and put a slight slanted firing pin width gully just below the case rim on the barrel face the combination of which will guide a protruding pin back into the block instead of allowing it to hang up.

It would take the pressure off of it, but the tip could still be protruding enough to hang up and break. This issue is confusing to me as unless I'm mistaken and don't think I am, I've been advised at C Sharps Arms that repeated dropping of the block may cause damage to the FP. From the looks of the drawings I have of an original, I do not see how that is possible since the spur provides the means for the FP to be driven back automatically and mechanically when the block is dropped.

	There are symptoms that will show whether the pin tip is dragging as the block drops. You possibly could see drag marks on the brass or at the bottom of the barrel I have seen barrels with a small groove in them to insure that the firing pin tip does not hit it if the tip is protruding slightly. That said I have never had issues with link retracted firing pins.

Bob They sure look the same to me….other than Pat. date. The action missing the lever is the coil spring and a take-down action. The sears are different thicknesses but that could be just year of manufacture difference. The coil spring action has the thicker sear. I did not try to switch the two triggers around. Bob
