It was done here by several very well skilled individuals, but even they had problems with breaking barrels, and other issues, due to the Hardness of the metal.I would like to machine an o-ring groove in the barrel of my USP like the tactical/expert. Has anybody done that?

Buy aftermarket with a o'ring, or just skip it.
+10! Its a fact that 95% of all self defense shootings occur at 21ft and closer - seeing as how the o-ring may/may not improve accuracy at 25 yards+, I see no reason to try to improve the accuracy of a standard USP, plus the major head aches of a ruined barrel. One of my full size USP .45 will shoot 2" groups all day at 25 yards with practice ammo/fixed night sights, thats plenty off accuracy for any gunfight - thats what the standard USP pistol what designed for.Leave it stock -- there's no reason to change its design to something else. Accuracy for defensive handguns is a moot point; as long as you can maintain a decent group out to 10 yards, and your POI is close to your POA, you're good to go for self-defense...
