I've found that, unlike my Glock 17, my Glock 26 is very tolerant of limp-wristing. I deliberately shot it while gripping it loosely with an unlocked wrist and a flimsy thumb-and-index-finger-only grip (middle, ring, and pinky "open") with no malfunctions.
My 9mm BHP and Les Baer Premier II .45 also seem insensitive to limp wristing.
Note that switching to higher impulse ammo (+P or +P+, or a heavier bullet) will sometimes "cure" limp wrist malfunctions that occur with standard ammo.
