I recently acquired a Palmer 44 Mag with two barrels and man was the DA heavy and gritty. I ended up giving it a trigger job on the DA and it benefited alot from it, without changing any springs. The sear surfaces definitely were rough and needed some reprofiling from the factory. The pull is smoother, lighter and more predictable. It's easier to stage up the trigger after the cylinder actuation is done and the hammer is gonna drop.
I'll need to get a trigger guage on it, I wish I did it before the trigger job.
Anyone else have similar experiences on theirs?

Dans are not know so much for their DA. Most large frame are shot in SA. That is usually slick. Small frame guns benefit from smoothing the inside sideplate and frame and Wolff reduced power springs, especially the trigger return spring. DW lockwork is MIM and only hardened on the outside surface. You have to be very careful not to smooth too much or the critical surfaces will wear.

Not sure if mine have had work done on them, but all my small, large, super, have fantastic SA triggers that rival my 1911's

I am a bit anal about all of my revolvers and do a lot of trigger work on them. I have taken several DWs apart, polished the trigger parts and changed springs on some. All of mine older and well used so they needed some attention. I am not really looking for a lighter trigger pull in DA, I want a smoother pull however I shoot it.
Good luck with the changes.

I’m sure it’s okay, the notch in the trigger for the bolt engagement is cut into the mim trigger as well as the SA notch in the trigger surface and the DA trigger surface are polished/cut. I highly doubt these were done and the parts when back into hardening since they would at that point be paired. If anything the DA surface on the trigger of my gun was getting a lot of wear due to the DA sear surface on the hammer was very very rough and unfinished. It actually had grooves I had to polish out. So if anything that was already wearing through my hardened surfaces.
Edit: Where did you hear that DW lock work is MIM and only hardened on the outside? Because Keith confirmed to me the DW internals are cast not MIM.

The trigger was mostly heavy due to how rough the engagement surface was.

I think early Dans were MIM. Somewhere over the years I think they must have upgraded.

Yea, I took your advice and ordered a spare hammer strut. From the looks of the replacement ones, mine was cast really really rough and had a very prominent cast seam offset from the center. This seam was gouging the trigger.
Does the strut need to be fitted?

Keith confirmed that these parts are through hardened not surface hardened via email to me. He said they never used MIM on their revolvers.

Could you clarify how you know they are MIM and surface hardened? I saw you repeat this quite a few times in numerous threads.

Sideswipe, much of the information that was available on the forum and on the internet has been lost. If you research Karl Lewis you may find a reference. One of the innovative things he did was using sintered metal(MIM) for much of the lockwork. This enabled DW to produce the guns for a reasonable price and allowed owners to perform repairs that would otherwise require a trip to the factory or gunsmith. DWs are basically a modular firearm. Even hands and rachet are usually interchangable because the parts the were fitted to were all the same. The present employees of Dan Wesson /CZ/Colt are and have been for decades woefully ignorant of many facts from before the move to Norwich. If I can find some old sources I will bring it to your attention.

Thanks snake-eye, interesting reading.

I learnt through your post that the practice of judging if a part is produced by the mim process by the surface roughness is also unscientific, there are a lot of factors that affect the surface roughness, it can also be caused by the rougher particles used in the mim process, as well as the fact that the part is not surface treated, polished and ground
I often make some gun parts, gun metal parts usually have some special properties, so they are usually made of special alloys, the manufacturing cycle of gun parts is very long, which is mainly limited by the level of craftsmanship, gun parts need to be precision machined and surface treated, some parts are made by MIM process to ensure their accuracy and reliability.
