A couple things. First: I learned that my Remington R51 isn't trusted by many gun experts. Second, I learned that the m&p shield is more popular than I realized( four of twelve participants had identical shields) I, familiar as I am with firearms but lacking any formal training, learned a lot about grip and pistol control. My wife has little experience with firearms, especially my R51. The two didn't jive. I never thought much about it but nearly all her shooting experience (2,000-3,000 rnds plinking) was with a single action .22 revolver. Aside from not knowing how to control recoil during drills, she had a failure to feed do to not fully seating the magazine. She also had an issue with the grip safety. She wouldn't completely depress it and a failure to fire resulted. Then continue to fumble with clearing the action until an instructor stepped in. Happened a few times They let her know she was probably not fully engaging the safety. I kinda blew that one, sorry Honey. I had a dud round but no other trouble with the R51. I did realize that I dislike the grip safety after my wife's dismal familiarity. I have had trouble with it a time or two myself. Got me thinking, how many times have I drawn a bead on rabbits or ducks only to pull the trigger three or four times before realizing I forgot to hit the safety? I see an external safetey-less compact handgun in the near future.
