Bisley hammer/trigger in OM Blackhawk

I'm sure this has been covered before but what is involved in installing the Bisley hammer/trigger in the old model Blackhawk?

After market parts, there is a group buy on them over at Single Actions.

Hope this helps.

Thanks, I appreciate the info.

If I understand, you just want to add a Bisley hammer and trigger to an OM BH with the standard OM grip frame.

1. You'll need a Bisley hammer made for the OM by Power Customs:

But since it's made to be used with a Bisley grip frame, it needs the hump ground down to fit the standard plow-handle grip frame, by scribing the hump on your factory hammer onto the Bisley. Then gringing off and polishing.


2. You'll need a Clements OM adapted Bisley trigger. This wide trigger will require the OM trigger slot widened unless you use an OM Super BH grip frame or Old Army steel grip frame, blue or stainless steel. The shelf on the back of the trigger will have to be ground off to work with the OM trigger return spring.

Thanks, Hondo. That's the info I was looking for.

Powers actually now offers s bisley spurred hammer for old model Rugers with the regular grip frame. They just do not come with the hammer plunger and spring.

salover,

My pleasure. If you move ahead on this project and have questions, just give a holler.

Hi Robb,

I know they do for the new model, but have not found it on their website for the OM. Do you have a link to it?

Thank you,

Here you go sir.

Thanks, Hondo. If I do proceed I'm sure I'll have more questions. I'm kicking the idea around right now. It's about the last thing I can think of to do to it. It's the old model converted to 44 Spec/44-40 with a ported Pacnor 5 1/2 in barrel, case hardened by Turnbull's, currently being engraved and sports Sambar Stags. I was having problems with the 44-40 cylinder not cycling with ammo, hanging up in the firing position and I believe it was you that told me the case heads of the Spec and 44-40 were .005 different. I sent the cylinder to Bowen and had it corrected. You and this forum are a world of info and guys like me appreciate the sharing of your knowledge. Thank you.

Thanks, Robb. I've book marked this site. Appreciate it.

Thanks Robb!

That's the same hammer I linked to. It shows a Bisley hammer with a hump for a Bisley grip, but maybe it's just the wrong photo.

Although if it is shaped for a standard plow handle grip frame, that would mean PC doesn't make an OM Bisley hammer for use with a Bisley grip installed on an old model, because there's no other Bisley hammer listed for an OM.

Have you used one of these before?

Thanks again,

I sent Power Custom this message:

Gentlemen:

The hammer below on your site for an OM Ruger single action shows a Bisley hammer with a large hump for use with a Bisley grip frame. Is that correct, or is the hump trimmed to work with the standard OM plow handle grip frame?

Thanks very much,
Jim Carter

"Yes, it has the bigger hump on it for the Bisley Grip Frame. If it is too big you can file the inside of the grip frame to make it work if it is too big. Thanks, Randall Power http://www.powercustom.com Ph# 1-573-372-5684"

Thanks for clarifying that Jim, I stand corrected but like you said, removing the hump is just a matter of a few minutes work in the shop.
