Yes, I do. I don't shoot it a lot with that ammo, though. I run 148 gr WC's through it for practice, and then one or two cylinders of the +P's 3-4 times a year to be sure the sights are still regulated out to 25 yards.
Not that the fixed S&W iron sights are gonna move unless I knock the barrel out of the frame! (And one nice thing about the CTC lasergrips is the zero doesn't seem to wander at all.)
If I ever shoot my 442 "loose", I'll send it back to S&W and get it "tightened". I've done that with my M65 and an old M15 that I sold last year, and they do fine work of this type for a very reasonable price.
