I am a noob here, so be kind😆
Any way, I'm looking for a bobbed hammer to replace the spurless hammer on my 6904. i need one from a 39xx or 59xx, And will use my existing connector. Anybody have one?
 
You will want to locate a spurred hammer from one of the full-size TDA guns like a 5906. Good idea to keep it the same type of hammer construction (forged vs MIM) as your 6904. Chances are your 6904 has forged parts, so just try and find a spurred hammer that looks the same.

The hammer strut from a full-sized pistol will be too long, and you will need a roll pin punch to remove the roll pin from each hammer and swap the spurred hammer onto your smaller 6904 strut. Then it's a matter of dropping the hammer back in and reassembling your 6904 frame.

If you're not familiar with how to do that, it might be a good idea to have a gunsmith do it for you.
 
Did this to my 3913, 4516, & 469 so I could cock the hammer for a 1st round SA shot. If I could not have swapped hammers, I would never bought any of these guns. GARY
 
Photos tell the tale.....

“Bobbed” is simply just a hammer with the “spur” removed rendering SA/DA gun to DAO.

Certainly, you would agree, removing the hammer spur ("bobbing") will not, and does not, relegate a pistol to DAO only... Although not as easy, the hammer can still be cocked to SA...

This is incorrect for two reasons.

1. On a DA/SA semiauto, after the first DA shot, the gun will be cocked in SA mode whether the hammer has a spur on it or not.

2. Even with no spur, you can still cock the hammer if you stage the trigger just a bit first.

Some other mod to the hammer can make a DA/SA gun a DAO, but the spur is just an appendage for operator convenience, and doesn't affect the operation of the action itself.

Yessir, I do agree.

I didn’t mean to light a firestorm as my comments were related to a bobbed hammer on a revolver as depicted in the photos.

A bobbed hammer on a revolver can indeed be cocked for SA operation, albeit very carefully.

I offer that the one of the main reasons for bobbing a hammer, in this case on a revolver primarily used for self-defense, is to be able to draw smoothly from conceal, point and shoot under duress without having to give thought to cocking a hammer for a more precise, aimed shot.

These three, (and some others,) I replaced the bobbed hammers on. A couple, like my CS9 and CS45 I will probably return to the original bobbed hammers. The 4516-2 and a few others I will not.

Pictures were originally for a MIM vs the other two question someone had, but kinda work again here.

Bobbed used to have spur, but removed. Spurless made that way from factory. But often times terms used interchangeable....as they both refer to hammer fired gun without a spur for cocking into single action trigger mode. Many small concealed carry guns, revolvers like 642, autos like 3913/cs9/etc are made from factory without spurs....as they can easily get caught on hem, shirt, pocket purse opening,etc upon drawing. And these guns are not intended for long range bullseye guns, but for close quarter self defense where a premium is placed on fast unheeded presentation.
 
Thanks, I just want to be able to manually cock it. Love the gun, not the long SA trigger pull.
 
Yeah, I believe that's what I need. I found it in Numrich, but they want around $58. I dont want one THAT badly.

The (first) long trigger pull (hammer down) is the double action pull.

Did this... so I could cock the hammer for a 1st round SA shot.

Do people find it hard to lightly squeeze the trigger, just enough, to raise the hammer up slightly, exposing the ridges on the top of the bobbed hammer, then fully cocking it using your thumb?

That's an accident waiting to happen. GARY.
 
Have you shot your new gun yet? Other than dry firing?

After inserting loaded mag, when you rack the slide to chamber 1st round, and safety is off, it will immediately be ready to fire in single action (hammer cocked) mode. Each subsequent shot will also be in single action mode until mag is empty. Then slide locks back, you insert another mag, boomarang slide to chamber first round, repeat, repeat, repeat. You could literally shoot 1000 rounds at the range, with every single shot in single action (hammer cocked) mode...without ever manually cocking the hammer (by trigger staging), or having to pull through a full double action trigger.

Now...when you insert mag, and chamber 1st round, and safety is ON, it will chamber round and drop hammer (de-cock) putting gun in double action mode. First pull is long DA, next and all subsequent shots will be in single action. You are only having first shot in DA mode when you are carrying weapon (this gun designed for concealed carry...so spur cannot catch on hem of shirt, etc). That long DA pull is the "safety" really...as many of of us carry the gun in DA mode with safety "off" (use as decocker only). If at the range, and in de-cocked mode, you can keep gun pointed down range and stage trigger and cock hammer as you mentioned. No problem doing that, would be hard to "accidentally" pull through full DA. BUT...it's good to practice that DA pull, as that is how you would normally use the gun in defensive situation; 1st shot DA / follow up shots SA.

Thanks, I'm familiar with the gun. Just wanted to see if I liked it better with a spurred hammer.

Sorry, "SA" was a typo.

Gotcha. Didn't mean to insult, but wasn't sure if you were familiar with traditional DA/SA function. Lots of folks these days grew up on striker fired like Glocks, etc., and don't understand the "reasons" behind DA/SA as well as differences. I like spur hammers for target shooting and range guns, and spurless for carry. Although I do carry my walther PPK, but it has that rounded spur type, that is less prone to catch on stuff. See pic. This is nice compromise IMHO between spur vs no spur.

What about in the real world? It's 3am, my wife, & I are asleep in bed, & I hear a noise in the living room. My wife is next to me, & nobody else is living in my home. I grab my 469, & it already has one in the chamber, but the hammer is down. I want that hammer back for a single action first shot, but with all the excitement, I do NOT feel good with pulling the trigger enough to grab the hammer to cock it, & possible shoot myself in the foot. This will not happen with me, because I installed a 459 hammer in my gun, & can safely cock it as I look for the dirt bag who broke into my house. So the problem is not at the range when racking the slide to shoot the first round. The problem is in the real world when the gun already has one in the pipe, & the hammer needs to be cocked. I have already "repaired" my 3913, 4516, & 469. GARY

As I noted....spurless for carry, spurred for target and range.
should have added "night stand" to the latter. But if I only had one pistol for everything, I'd still go with spurless. Would rather have to shoot a BG in my house with DA first shot, than worry about spur hanging up on my clothing with IWB holster. But for me, it's my mossberg 500 18" pump shotgun with green laser (no sights needed) and #7 buck by my bed. I live in condo with neighbors on other side of walls...so over penetration is a concern for handgun home defense.

That's what I'm talking about.
Also, when I wrote "bobbed" I meant a shortened, rounded hammer spur, as opposed to a true "spur". The 6904 has a "spurless" hammer. Maybe my nomenclature is off. It's a matter of semantics, I guess.
 
In general, I believe that most people view bobbed and spurless as the same thing. One advantage of cocking a spurred hammer vs. a spurless is that the firing pin safety is still in place, since the trigger is not being depressed.

I personally am on the other side of the fence, as I do not like spurred hammers on my 3rd Gens. As a matter of fact, I've ground the spurs off of a number of my S&W 3rd Gen 9mm's, including a few 5906 variants that get used for home protection.

Snagging the hammer spur is a concern, but mainly I don't want to be adding another step in my muscle memory when changing my pistol from safe to fire. I could see myself desperately trying to cock the hammer on a gun with the safety still down if I was stressed out. IMO it's better to practice the first DAO shot and become accurate with that than relying on cocking the hammer for all shots. Just my opinion, of course. :)
