Can I swap my Taurus 327's spured hammer with my Taurus 905's spurless hammer?

Question is in the title folks.

I have just picked up a Taurus 905 with a 3" barrel. I had planned to add a pair of BK grips to them, but he is currently all sold out. So instead I decided to just steal the one I had on my 327,and put the stock Taurus rubber grips back on it since they play well with speed loaders.

While I had the two revolvers next to each other and the grips off, I got to thinking how nice it would be if the hammer on the 327 was spurless to help with pocket carry, and how much nicer it would be if the hammer on the 905 had a spur so I could enjoy shooting it single action at the range every once and awhile.

Which leads me to the question can I swap their hammers? The frames are practically identical as far as I can tell, but the 905 is a 5 shooter and the 327 is a 6. If these were heritage revolvers I couldn't swap the hammers because of that. Does the same apply to Taurus hammers, or are they capacity neutral like Charter Arms hammers? 20240204_192007.jpg

In my opinion, yes, you can swap the hammers since the two models seem of the same generation. The fastest way is to remove the side plates and see yourself if there is any difference between the two hammers. It makes alot of sense to swap those hammers and make the 2'' optimized for pocket carry and the 3'' more suitable for shooting.
 
Can you buy a hammer to fit your want? May be easier and a bit more clear if they say it fits your model. Fair amount of parts out in parts kits or singles on ebay.

I would go that way so you're only moding one firearm at a time. With my luck, both of them would be a bit wonky when done.

You might have to swap the triggers, too.

The trigger fitted to the DAO gun might not engage the single action notch on the DA/SA hammer properly. Or, maybe it will.

It's all about the hammer. It's the hammer that have the single action notch.

But I think that there are high chances that the hammer of the 3'' revolver was only bobbed and still have the SA notch.

Taurus doesn't sell spare parts. Maybe a spare hammer can be found somewhere online but it's not like a S&W that you have a model number and a dash number to help you to find the right part for your model.

"maybe"

The stud that the hammer pivots on changed diameter some year recently. I think 2021. (I ran into this when I bought a "Gunbuster" parts kit for 856 that included a spurless hammer. Made in 2020, would not fit my 2021 or 2023 856s due to this issue.

The difference is visible in this pic.

If it was me, and I already had money in that hammer that didn't fit, I would take it to the drill press and try drilling out the pivot hole.
You already have something you can't use, so if it doesn't work; oh well.
 
I don’t think the 905s are offered with a spur less hammer and in your picture the edge of the hammer looks like it has been cut or ground off. I am thinking about doing that to my 905 hammer. You could do that to your other gun. Have you had any failures to fire in your 905?

To the degree that Taui mimic S&Ws, this looks like good news regarding a swap. The double action sear is present; the single action notch is blanked.

Ignoring the hammer pivot issue, the spurless hammer has the springloaded double action sear.
Again, good news for the swap.

My question would be timing; is there a difference in the hand, or elsewhere, to make the cylinder carry up?
I think swapping is the easiest way to see. The hand may need to be addressed.
Good luck; the changes makes sense.

I think that if the two hammers are identical and can be swappped, it's a better idea to swap the hands between the two so that each hand stays with the revolver where it was originally installed. That's because the hand has usually some hand fitting primaily to fit it to the rotation star.

Some experimentation is in order. I would certainly, clearly mark which hand is which, and then swap things around to see what works. One cylinder will make 1/6th of a revolution, the other 1/5th. There has to be something different, that makes that happen.
But keep track, carefully.

Thanks for all the feedback everyone. The 905 is shooting so nicely in double action that I am actually a bit hesitant to give swapping the hammers a shot.

Will probably pop the plates off both this weekend and take a look at them to see how close they actually are. If I can do this I will try to take pics and share them.
 
Been mulling on this; Oninotaki, even before pulling the side plate, have a look at the ratchet on the back of the cylinder. It may be where the difference in rotation occurs.
Keep us posted!
