Beavertails like the ones Austin Behlert did back in the 70's involve a LOT of welding on the frame. Most of the work the OP has done didn't necessitate a full refinish. That would....
I still don't understand why Springfield didn't do that as a design feature of the SA-35 when they had a...
Most European companies are not big on Extended Slide Stops and don't offer them, because their dogma is to "slingshot" the slide closed after a reload. Many of their guns don't even have an exposed Slide Release, with the Slide Stop being internal. A certain very-popular European handgun was...
That Locking Block pin is an absolute MO-FO. It is a super-tight press fit into the metal Locking Block itself. Driving it out is a bear due to being tight in the block, but only supported by plastic outside of the block. Scott Folk from Apex Tactical did a YouTube video on this very topic....
Not local, but Scott Pilkington in Monteagle, TN is my go-to for this. He was the armorer for the USA Shooting Olympic teams for the past few games.

I'd only want that done by EDM machining and would probably use Magna-port. You should only have to ship the top end to them and they're usually pretty fast.

I'm not saying that you have a steep uphill journey, but you might want to lace up your climbing boots; you're entering a fine balancing act.
An expansion chamber compensator retards the initial rearward movement of the slide, necessitating the lower spring weight like you suspect.
The fine...
It appears that the Bolt (the internal part attached to the Thumbpiece [aka Cylinder Release]) is not retracting out of the way with the cylinder closed. That will block the hammer from moving.
Could be the angle, but looks like that from here.
Hopefully, whoever does this work knows to leave a good shoulder for the can to bear against. I've had customers wanting to thread hunting rifle barrels that were so thin that it would've left a shoulder that was only 0.040 to 0.050 deep. That's not a lot of material to bear against....
The slot you are referring to is for the Cylinder Stop (the part that keeps the cylinder from turning). It appears from the pic that the Cylinder Stop is there, but is stuck in the "down" position. That could be from a number of things, but my first vote would be for "some sort of debris is in...
I would be careful about building an ultra-light.
I got on a kick where I reasoned that a super-light rifle would be the cat's meow for 3-Gun, USArms, etc.-style competitions. I mean, it'd be easier running with a light gun, a light gun should swing better from target to target, 5.56 has...
I have a lot of customers who pay me to clean their guns. I am willing to go "total disassemble", as opposed to a simple field strip that most will do. One guy goes on a few exotic hunting trips each year. I get his collection after he's done with that season. Others are competition shooters...
The reason that you have the large gap on the Beavertail is that the Ed Brown is designed for a .250 radius on the frame ears, not the "contoured" cut that your OEM frame has. I would try to find a Wilson Combat beavertail (not the drop-in one, but the one that requires fitting). It appears...
I will go out on a limb here and assume that he's talking about Carrier Keys (that's the only gas system item that gets torqued, other than Gas Block setscrews).
I use a 55 INCH-pound torque limiter from Fix-It Sticks. I've checked the calibration on them and they're pretty dog-gone accurate...
Was it going fully into the "engaged" position once it started moving? There is a very small window where it'll move a little, sorta-kinda block the sear, but then get pushed off when the trigger is pulled.
A good light and a magnifier are your friends now, so you can see exactly what's going...
The DX front sight, if I recall correctly, had a plunger that was pressed in from the front to release the front sight so it could be removed. That is what is pictured in your post.
If it is a simple pinned Front Sight, try this...
