new-to-me 442-2 questions

[hotrod150]

I just bought a used 442-2 with a CTY serial number. I generally prefer vintage j-frames but previously owned another 442-2 with a DAH s/n. I assumed when I bought this one that it was made a little prior to my other one (2006), but low and behold this one came with the box etc and the fired case envelope was marked 3/8/2013. Additionally the Shakespearian (or whatever) code date on the box label is 3067 which calculates out to 3/28/13 also. Guess that just goes to prove that you can't put anything past Smith and Wesson!
I replaced the rebound spring with a 13 pounder from Wolff, the one that came out is painted blue. Does S&W color-code their springs? I watched an Apex kit video and the Apex spring was green while the one they removed from blue.
I'm also curious if anyone had modified the MIM trigger? I generally prefer a narrow smooth trigger for DA shooting, this one of course has the factory wide smooth trigger. I can probably live with the width but the tip of the trigger has sharp corners which bit me on the last 442. Has anyone modified a MIM trigger- in particular ground on one? I'm joking of course (pretty much), but I don't know what's inside a "metal-injection-molded" part-- for all I know, it's metallic jelly which will all squirt out when I round off the trigger blade.
Does anyone have a copy of a parts diagram for this gun which they can post or post a link to? I'm mainly curious as to the official name of the two main infernal lock parts. I disabled the lock by removing the aft-most part-- I call it the "locking thingie" but have heard it called the flag. This leaves the forward-most part (the "keyhole thingie") in place so it is not quite so apparent that the lock has been removed-- the only external indication is the itty-bitty empty hole aft of the thumbpiece.

Buddy––on YouTube go to 4eversnubby (he's a poster) and look for his video on how to remove the internal lock from a 442. I did that with mine, and it was fun. The outside of the gun looks just exactly as it did when new, but there's no internal mechanism to possibly jam at a bad time, It's a tiny little thing that comes out––I put it in a little baggie and keep it in the blue box for when selling time comes around.

You did n't read my entire post-- that's exactly what I did already. It does leave an empty pivot hole for the "flag" but otherwise no external indication that the lock is disabled/removed.
Still curious about the blue rebound spring, and S&W's official name for the lock parts.

Hey again: I think you may be right. I looked at my 442, and sure enough, there's a little hole there in the frame behind the thumb-thing that releases the cylinder. Guess I just never paid attention to it and thought it was there for lubrication or something. As I recall 4eversnubby names the parts there in his YouTube video on how to remove the internal lock.

That video is very well done, but being an impatient type I think it takes about twice as long as it should. At three minutes into the video, he's just finally removing the sideplate!
The narator does identify the removed parts as the "flag", but the only main peice (which is the "cam" maybe?) is not identified. That may be what everyone calls these parts, but not necesarily what S&W calls them. For example, what you call the "thumb-thing" S&W calls the thumbpiece. What a lot of people call the crane, S&W calls the yoke.
