Stainless part in blued firearms, and YouTube video accuracy.
Is there any issue using a stainless steel part (like a 6906 drawbar) in a blued pistol (like a 6904)?
Do y’all think these YouTube videos are accurate and worth following for disassembly? What about all the polishing he does, worth it or just cosmetic?

For me, his videos were invaluable. Wish I could buy the guy a beer.

The stainless parts are the same as the carbon steel parts when it comes to interchanging. The only issue comes when replacing forged parts with MIM parts. Forged hammers and sears need to stay together, MIM hammers and sears need to stay together, do not mix a MIM hammer or sear with a forged hammer or sear.

I have a 2nd gen drawbar, sear, and spurless hammer in a 3rd gen 5906. The videos were a major help. Now I can disassemble do a deep clean and reassemble without watching. I polished my 4506-1 and it seem to smooth it out a bit. Might of dropped .5lbs in pull but can't remember as I did it years ago.

I have heard this repeated many times (don't mix MIM and forged hammers and sears) and the only prohibition I can find refers to the early DAO pistols which had a different geometry to the sears and hammers.
Nothing to do with the TDA (DA/SA) pistols.
What harm comes from mixing MIM and forged hammers and sears?
John?

The same drawbar was used in the 6906/6904 & 5906/5904 guns. Part #26232000
You could find some parts made in both stainless and carbon steel (blued), like ejectors, extractors, firing pins & firing pin safety levers. (Just to name some of the top of my head.)
The older hammers were all machined carbon steel, and came in either plain blue/black or flash-chromed.
Later on MIM parts like slidestop and manual safety assemblies were made of stainless MIM, and left in either plain stainless finish or had a black finish applied.
Didn't watch the linked video. Sorry. I can only offer that I've seen an amazing array of examples of what not to do posted as video clips by individuals online.

He lost me when he pulled the trigger with the hammer in the full cock position...... with the slide removed. Twice. Painful to watch.
That's as far as I got. Had to look away.

The title says it all for me.
As for "cosmetics," I now have more than a few S&W 3rd generation sidearms that have convinced me my time was well spent with those videos.
Later.

You tube videos have become my first go to thing when I'm looking at how to take something apart, not just guns. So much better than those exploded view drawings of the past or bad pics that don't really help much at all when you have a gun down to a pile of parts. My first 5906 had the broken trigger spring and I actually had one and the YT video showed me what to do.
Last one where I really needed help was when I converted a Sig P226 from DAO to DA/SA using parts from Ebay. Without those videos, it would have taken so much longer. Even with it, it was a hassle to do.

Yikes! Don't try that at home! You might just end up with a ruined frame. I wouldn't want that guy working on my gun. What's with that hammer with a hole in it? I can't remember ever running into one. Is it factory?

Not entirely certain, but it also what I have always heard. Perhaps there is a difference in surface hardness or perhaps an engagement angle mismatch?

I've heard it a number of times myself.
I'm also probably guilty of repeating it without actually thinking about it.
Al Gore hadn't invented it yet when Mark Twain said it, but he must have been prognosticating the internet when he said, "A falsehood will make its way around the world before the truth has a chance to get its shoes on."

Not that I can tell, and I haven't heard any evidence supporting the MIM with MIM only story.
