I was wondering if anyone has an extra safety transfer bar for a Ruger Blackhawk and you’d be willing to measure the overall length for me.
I had one that has broke while dry firing and so far have ordered 2 from Ruger, when installed the top of the bar sits below the bottom of the firing pin when the trigger is pulled fully backwards.
I’m wanting to get the length so I can call Ruger again tomorrow and start over again with at least a baseline idea of what to tell them what I need. I’m thinking they’ve just got the wrong part in the envelope for the Blackhawk.
Thanks hunter966.

Yes sir, it’s a locking base pin and it’s all the way in and locked. I measured one of the bars Ruger sent me and it comes out at 1.682 with a dial micrometer.

I just measured the stainless transfer bars I have and the one from a .22 Single-Six which measured 1.56 inches in length and one from a .44 SuperB that measured 1.7 inches in length.

Thanks petep, I’ll write them down when I call Ruger.

As noted over on the Ruger Forum,, measure the broken one as well.
Some of my NM's with the transfer bars do not totally cover the firing pin when fully cocked.

If you're breaking transfer bars you probably have insufficient clearance on the hammer and you're battering them to death.

"I had one that has broke while dry firing....
.... installed [new transfer bar] the top of the bar sits below the bottom of the firing pin when the trigger is pulled fully backwards.” ----hunter966
*****
hunter966.... I broke the transfer bar in a S410N “Silhouette Super” .44 while on the quest to set the 40x40 Revolver Record in silhouette. I don’t think the transfer bar was changed when Ruger set back the barrel to eliminate forcing cone erosion. The revolver had some rounds through it. Transfer bar moved freely; did not bind. Upon hearing of the breakage, Bill Ruger, Jr., clamped a Super Blackhawk in the dry-fire machine in the Southport factory and ran it for a week. He finally shut off the dry fire machine, as “The electricity is cutting into my beer money.” There was no sign of harm to revolver or lockwork.
Check for binding * Cock hammer. * Squeeze trigger... continue holding rearward. * Press hammer into frame with thumb of off hand. Continue pressure on hammer. * Release trigger. Trigger immediately resets. If trigger does not reset with hammer pressed forward, transfer bar is pinched between hammer & frame.
Before thinning the face of a transfer bar that binds between Hammer & frame, I would try another transfer bar. If it is necessary to remove metal, do it on transfer bar, not frame.
Transfer bar operation Transfer bar attaches to trigger. As trigger resets, transfer bar drops below firing pin. As hammer is cocked, trigger moves rearward and transfer bar rises to overlap firing pin. At full cock transfer bar may cover just part of the firing pin. Trigger is squeezed.... at hammer fall, trigger sweeps rearward. Rearward sweep of trigger further raises transfer bar.
Fugitive trigger An inferior trigger job results in a FUGITIVE TRIGGER. At hammer fall, the trigger a) remains stationary, b) bounces, or c) kicks forward. The transfer bar drops below firing pin. Result: MISFIRE. (Note: no revolver SA or DA, is immune to problems caused by a fugitive trigger job.)
Short transfer bar Obviously, a transfer bar which can’t reach the firing pin when the trigger is depressed cannot fire the gun. Check, also, for a bevel along the top front edge of the transfer bar, which may limit firing pin movement. David Bradshaw

I don’t know if this picture will show as I’ve never tried an image hosting site. The transfer bar is just too short. Thanks Mr.Bradshaw I’ll check the trigger and transfer bar tightness when I get me a new one. The gun has went to and came back from Jack Huntington, I’ve shot a bunch of rounds through it since I’ve had it back and I believe the trigger is fine.

FULL COCK----transfer bar should cover 1/2-firing pin. The transfer bar rises a very short distance between full cock & hammer fall. Possibilities * Wrong transfer bar (too short). * Transfer bar not attached to trigger. * Broken transfer bar. A broken or detached transfer bar locks up the action, if not on the first cock, the next. David Bradshaw.

I really think Ruger has got a mix up in their parts bin. This is the second of the two they sent me and they’re both the same length.
I disassembled it again last night and the bar-trigger is put together correct and nothing is binding up.
I sent the picture to Ruger C.S. and so I guess we’ll see.

Fugitive triggerAn inferior trigger job results in a FUGITIVE TRIGGER. At hammer fall, the trigger a) remains stationary, b) bounces, or c) kicks forward. The transfer bar drops below firing pin. Result: MISFIRE. (Note: no revolver SA or DA, is immune to problems caused by a fugitive trigger job.) Odd that the factory would perform a fugitive trigger job. My only BH is a .41 made in 1980 that my father bought for me. After much shooting, but way less than a silhouette shooter would put through a gun, I started getting misfires. Finally observed that the top of the transfer bar had an indentation, apparently from contact with the firing pin. The bar covered about half of the firing pin, I faulted my grip as being too gentle/light/wimpy and letting the trigger return spring move the trigger forward and drop the bar or at least not raise it any further when I tripped the sear. Holding the hammer and pulling the trigger fully back, then slipping the hammer to fire the gun of course was more than sufficient to fire the gun but who shoots like that other than a fan-firing speedster? I called Ruger and they sent me a new transfer bar, this one nearly covers the full firing pin surface where it contacts--they never confessed to a fugitive trigger. Pulling the trigger lifts it a little more, as you can imagine there have been no further problems. Hope they get you what you need to get your gun up and running, and soon!

UPDATE: I received the new transfer bar today from Ruger and this one is the one! I took it out of the envelope and just by looking at it I could tell it was longer than the previous two they had sent me.
Had it installed in 10 minutes too.
Mr. Bradshaw, I ran the Blackhawk through the test’s you listed and it passed them all. I just wished it was morning so I could do a little shooting now.
Thank ya’ll for all the help and suggestions. hunter966
