About triggers, my wife got a M&P 9C and that trigger sucks balls. We did a class where everyone had to shoot everyone elses pistol and get hits on steel about 20 yards away. When it came to using her gun, even very experienced shooters had trouble because they were used to their tuned triggers and not a shitty factory one like the 9C.
I remember that day. I was thinking (to myself), that girl is pretty hot but all her shots are pulling really low. We had a friendly competition at the end of the day where the teams laid their handguns on the firing line and rotated until everyone shot every gun. This was a competition between teams so it was pick up the gun, insert mag and start firing. I think the first three (or all) of my shots went into the dirt IN FRONT of the steel. Yes that trigger sucked.
