wow you know more about the trigger group for sks than most: you will be the one to be asked.
Its unsafe because that block (sear) that holds the hammer is aligned with the guns axis of recoil. The only thing holding it in place against the recoil forces is friction and a mag latch spring.
thegazelle, RE the flying empties, please check out the "Helpful hints ..." Sticky at http s://www.canadiangunnutz.com/forum/showthread.php/603359-Helpful-hints-to-DIY-for-Red-Rifles , Tip #2 both a. and b. The first is drilling holes in the gas tube to reduce the distance cases are thrown - mine is down to about 10 feet. The second changes the direction from 1-2-o'clock High to about 3-o'clock sideways; I'd advise using a 4" grinder instead of a Dremel, I used a Dremel and it took 3-4 discs and over 1/2 hour. A real grinder will only take minutes.
I don't have pics of the gas tube but here's the ejection port mod. I could have (and may yet) taken a bit more off.

^This. (There's also the friction of the hammer-to-seer engagement too)
But the friction between ALL the bearing surfaces in the sks trigger is intentional and integral to the design. The sks safety is essentially a "friction safey"
The sks has a crappy trigger pull for a very important reason. It was designed that way on purpose.
Took it to the range tonight. 80 rounds through it - no problems! Had to manually adjust the posts' windage and elevation pretty much from scratch as my laser bore sighter at home was completely and grossly inaccurate, as it turns out.
Very fun gun to shoot and once the adjustments were made it was decently accurate, given the liability of my lack of shooting skill.
Not a single issue with it tonight - no jams, no failure to ejects though I noticed that all the extractions flung the steel casings way ahead of me, way over the bench, which was interesting.
Used all Norinco red box, supposedly non-corrosive. I can clean it but am too curious to see whether or not the rumours are true that red box non-corrosive may have some corrosive primers mixed in. Guess I will check the gun in a few days and find out.
Regardless, I am going to drive some distance tomorrow to buy some Barnaul off another CGNer. All indications are that Barnaul is indeed non-corrosive.
Thanks again for everyone's feedback and assistance.
