So after swapping out springs etc back to factory on this Bisley, I had a thing happen while shooting with some snappy loads with AA7. Last cylinder full of the day, coming back from recoil, pulled the hammer back and it stopped about half way. I suspected cylinder float again but upon looking it over at home I discovered that if I hold the gun canted to the right, it will do that every time.
I can hold it "gangsta" style to the left (right handed), no problem, upside down, no problem. It only does it if holding it gangsta style right (left hand) and not even all the way, just a 20 degree cant will induce this.
I don't have a passel of these around to compare, but do have a FT .44 Special of later manufacture that wont do it, nor a stubby .44 mag., they cock no matter how you hold them.
Call me flummoxed!
Any ideas?

Sounds like the transfer bar could be snagging on something. Hard to say without looking at the gun.

I should mention too that I removed the free spin feature, I didn't like it. What I had to was go inside where the set screw came thru the recoil shield and file it down to nothing, PITA but it worked. I simply could not get the set screw out in the normal way.

Sounds like the transfer bar could be snagging on something. Hard to say without looking at the gun. I think you may be on to something. Two things. The bar seems under slight spring pressure on my other two guns, but on this Bisley it just flops around loose with no spring pressure at all. Is there a spring somewhere that keeps this pressure on the bar? When I induce the glitch, I don't see anything but if I hook the top left part of the bar and pull it back slightly, it allows the cylinder to complete its turn to full cock. Something is not right here. Probably owner induced! Guess I will have to tear it down again and see if I can figure this out. Oh great! |

The plunger on the end of the base pin puts pressure on the transfer bar.

Sounds like a base pin issue. Not holding the transfer bar back. |

That is exactly what was happening!! You guys were right on. I took the base pin out and compared it to several others I had for spares and it was decidedly shorter. I had at least 3 that would appear to work.
I put one in and could tell immediately it put spring pressure on the bar as suggested and now it works fine.
Hot damn you guys are good!
Thanks for your continued guidance!!

If the base pin was shorter but still had the spring and plunger, it sounds like the gun had a base pin from a medium frame gun.

It actually came with the proper length of pin, but it was the locking type so I swapped it out for another in the stash. I didn't notice that it was shorter than the other. Its only just a tad shorter, just enough to not push back on the bar.
