I looked at some real nice 4006sw today and I noticed some had a hole through the hammer when I looked at it . Was this a method to make it lighter. And did anyone notice this before? They were late guns with black trigger and hammers.

do you mean skeletonized?

I think he means like this one on my 1995 4006 I picked up last year.

I have no info on those guns with obviously lightened hammers.
DD, do you own any other 3rd gen TDA guns and notice a difference on trigger pull or more accuracy due to lighter weight hammer which is suppose to reduce hammer fall?
thanks for the pic

That photo is what I mean.It may be less to be pulling back when you pull the trigger but I could not feel much it seemed the same almost. If I didnt know the hole was their I could not tell . How can they drill a hammer like that ?

I recall seeing pix of Sigs with a similar hole. With the Sigs, it had something to do with some obscure German police bid requirement.
I expect this might be something more on the lines of the CDI factor.

I have several third generation 40's with this hammer. Difference between mine and Denver Dick's is that all of mine are alloy frames (4003 & 4013). I had wondered if the hammer was unique to lightweight frames. I guess that theory is shot now.

I have one just like that. Steel frame 4006 with fixed sights that I purchased new in 1996.

I have no others with the hole. I don't notice any difference regarding trigger pull or accuracy.

this is interesting.
was smith wesson planning to utilize the hole for a master lock and the plan was started and later scrubbed.

this is just a guess on my part.
when I packed my CQB on duty and shot it a bunch of times, including dry firing.
I was flattening the firing pin head (the part the hammer strikes)
maybe they were having issues with flattening of firing pin heads and this was their fix, by reduced hammer weight impacting on the firing pin, not spring weight so not to affect reliability.
again just a guess

Triaxle, if you look at the post above re 945 question and follow some of the many pictures of performance center 945's with holes in the hammer, I wouldn't be concerned. If it's good enough for the P.C. then it's probably ok.imho
I have an older police trade-in 4006 with such a hammer. I assume it is an older one because the safety and slide release are stainless, and the other style of hammer I've seen on newer third gen autos look like a MIM piece (and they have black safeties and slide release levers). This hammer doesn't look like MIM but I don't know that for sure.
I don't think this has to do with the hole, but it is completely obscured with the hammer at rest and the safety off, and a bit visible with the hammer at rest and the safety on.

Generally holes in hammers are put there to reduce their mass, lighten them. This is done to reduce "lock time" which in turn can improve accuracy.
Lock time is the time it takes from the time the sear breaks to the strike of the firing pin on the primer, igniting it. Single action revolvers typically have very long lock times while custom bullseye guns have much shorter lock times. The reason lock time is crucial to accuracy is that for the few milli-seconds that the shooter is "waiting" for the primer to light off the round after the hammer falls is usually when the sights are pulled off target, resulting in a miss.

Bullitholtz I think is right several years ago all the Colts and Colt clones in the combat matches that I had been to all had Commander hammers because they all thought it guickened the lock time, they may have all gone to titanium hammers now as I dont follow combat shooting any more but the hole in the hammer these folks though helped their scores.
I just picked up a used 4006 in the box with all the paper work and 3 pre ban yellow follower 11 round mags. It has a black hammer with the hole and a black trigger, SS slide stop and safety with a SN prefix of VCH. Product code on the box is 104402 and Spec. Ord. number is 4347 007 04. Funny thing is that the inside of the slide is marked Model 4003.
