For a friend, a few weeks ago I built up a 20L solid slide, 20lb ISM recoil spring, 6" Threaded 10MM barrel with our 10MM comp. When he came over to pick up the slide we test fired Remington 180gr & Blazer 200gr out of the upper. She was a gem to shoot. Depending on how hot the ammo; you can still run heavier recoil springs or step down to lighter ones when using weaker paper punching ammo.
With the set up above, the spent rounds were coming out about a foot, so a 22lb spring could have caused issues. VERY low muzzle rise; recoil felt like shooting a soft 40 S&W.
Since then I have built several long slides with the threaded/comp set up. But no one has told me what ammo they were using or how they performed. In my line of business, no news is good news.
Sorry, only two links to my buddies set up. He is working on graphics now. Guess we are going to custom engrave the whole slide soon.

Just curious on how it does. I seen the video on gun blast but if I am not mistaken he said he is using DT 135. I just wondered how it worked with 180grain or 200 grain ammo?
