Anything that retards slide action can result in a similar problem, whether that be "limp wristing" or a dirty or poorly lubricated or overheated pistol. One cause to consider, as discussed recently on this forum, is an out of spec firing pin retainer. Take the slide off. Try to move the firing pin retainer with a small wooden dowel or a screwdriver...if it rotates laterally it will touch the slide, impeding movement just enough to restrict ejection...perhaps less likely to retard extraction but no harm in looking.
