The accuracy issues are real, although somewhat overblown.
Some people say it's only the 5-inch Pro models that are affected, others say it's any full-size 9. Doesn't happen with all, but enough to be a consideration. Doesn't really raise it's head until you shoot at distance--25 yards and out.
Mine (circa 2010) is a pretty good shooter at 25 yards--with heavier bullets. 15 yards and in, it's good with everything.
