Ditto on the limp wrist. I see it alot in new shooters with both men and woman. Its a fairly common problem that can be frustrating to diagnose.
The woman picks up the gun, after coaching from her husband and she attempts to fire it. She busts off one or two shots and it starts hanging up. The husband, thinking it to be the gun, takes the gun, loads another mag and dumps the mag on target with no issues at all. Then he fires another mag and hand its off to the wife who shoots it again and it hangs up again. The husband without really understanding the issue, gets impatient with the wife, trys to forceably coach her and the wife gets frustrated with the husband for not being patient with her. She's probably not just real comfortable with the idea of shooting anyway and she is somewhat apprehensive and overly cautious about the whole thing.She hasnt come to terms yet of shooting a gun at a target with the idea of getting good enough to use it to kill someone and its not something that she really wants to confront or even think about.
One of the characteristics of the "limp wrist" is the "stove pipe" where the round that is ejected gets hung up in the slide and sticks straight up. What is happening is that the arm and hand are soaking up much of the energy that the slide uses to eject the round, making it more difficult for the pistol to work properly.
If the gun seems to be working properly for everyone else that shoots it, then its not the gun, its the shooter.With just a bit of coaching the problem can be fixed once its figured out.
Take a firm grip on the gun, extend the arm and stiffen up the wrist and elbow. It doesnt have to be board stiff, just stiff enough so that it doesnt absorb all the energy from the firing process. Its not hard to do and it usually comes easy once that person is familiar with the gun and shooting in general.
While it is true that some guns are more prone to "limp wristing" than others, its usally just a simple matter of diagnosing it and correcting the issue...and its a whole lot cheaper than cycling through guns to see what works and what doesnt.
