I really like the look of the bisley hammer and I'm working on a single six 22 WMR right now. I just want to know is it only looks or does it improve shooting. I changed the hammer on a Vaquero I had once but I did that to help give the larger area for cocking. I don't remember it improving that much but it did look cool. The hammer trigger sets are pricey if I spend that amount I'll have spent what I'll have in this pistol on grip frame, grips, and hammer. So why don't you all push me over the edge.
 
I don’t think a Bisley hammer dramatically improves shooting on a Single Six unless you are shooting one handed and need the lower hammer to make cocking the gun easier.

I insta Power Custom 1/2 cock hammer and trigger in mine which does improve the trigger in my opinion. They have a Bisley hammer option so if you like the look and/or want the lower hammer you can get both the look and better shooting.
 
The biggest 'problem' with installing a Bisley hammer is, do you cut the frame to fit the hammer or do you trim the hammer to fit the frame. Personally I trimmed the hammer to fit the frame. I also added a Bisley trigger to my SS.

As noted above,, the Bisley hammer/trigger set is pricey because of limited availability. And yes,, many prefer that style over the regular style for the ease of one handed operation. It'd all depend upon YOUR hands, and YOUR style of shooting.
Of course,, the looks of it appeal to many as well.

I've never tried to put a Bisley set into a Single-Six,, so I'm not sure if you need to modify the SS frame or the hammer like Frank mentions.

Only YOU can decide if you want it or not.

You do have to open up the trigger space a wee bit for the Bisley trigger. I found that I also had to take a few thousands off the trigger tip to fit in the grip without dragging. Time and patience works well.
 
I always modify the Bisley hammer 'hump' to match the grip frame 'ears' contour. I also remove part of the spur width at the front of the hammer.

And I always modify the trigger slot in the grip frame, not the Bisley trigger, it's part of the benefit of the Bisley trigger.

As I stated, I removed maybe a 10 thousandth of an inch off the trigger end so it wouldn't contact the trigger guard. Possibly the birds head grip frame, that I used, is ever so slightly a different dimension from the standard one.
 

Power Custom Half Cock Bisley Hammer and Trigger Kit for Ruger 22 and 32 Caliber Single Six​

Does one of these just drop in?
 
The Power Custom Bisley hammers in both the small and large configuration has a reduced hammer skirt diameter that will fit both Bisley and non-Bisley grip frames without modification. The Power Custom Bisley hammer skirt diameter is bigger than the Ruger Vaquero hammer skirt diameter and smaller than the Ruger Bisley hammer skirt diameter. The Power Custom Bisley and Vaquero hammers are a much better fit to non-Bisley grip frame hammer ears than Ruger hammers.

I have installed more than thirty of the Power Custom items in both Ruger and BFR single actions. Pics to follow, if requested.

Single Six with a Power Custom unmodified Bisley hammer and a slightly trimmed Power Custom Bisley trigger in a Ruger Super Blackhawk grip frame, nothing fancy, a shooter. The gun is not done and is dirty from...being a shooter.

You can be the judge. NM SBH spurred Single Six hammer vs OM Bisley spurred Single Six hammer vs a Factory OM Single Six hammer.
The NM SBH and OM Bisley are from Ronnie Wells / RW Gripframes. Pricey, but worth the money to me. After all, IT'S MY GUN;)

The one thing about the Bisley after market triggers; they have less curve than the Ruger Bisley trigger and is further back in the trigger guard, which is good if you have a fat trigger finger.

But I prefer the Ruger NM Bisley trigger. The lower tip of the trigger needs a slight shortening to fit in a standard trigger guard:

I have been shooting single action Rugers for 55 years. Single Sixes, Blackhawks, Vaqueros and one Bisley. I simply hate the Bisley Hammer.

If I were to switch I would put a SS or BH trigger on a Bisley, even the narrow one. But never switch the other way around.

I'm sure it's just me, but if I don't concentrate fully every time I cock the hammer, it slips and I skip a round.
 
"I'm sure it's just me, but if I don't concentrate fully every time I cock the hammer, it slips and I skip a round."

Are you using the firing hand or cocking one handed? When I use my SA handguns,, I most often use my off hand thumb to cock the hammer. SASS taught me the efficiency of that method.

I use the off hand.
 
Interesting.

Usually the off hand allows easier & more positive cocking. This goes directly to my often made comment & point of getting a gun to fit the owner's hands.
