The LC9 is not my favorite gun to shoot, but I carry it regularly and it is hard to beat as a concealed carry gun. I carry in a Disantis Nemesis pocket holster in summer, when wearing cargo shorts, and in a Galco Stow-n-Go IWB holster @ 4 o'clock in winter.
Very comfortable to carry in both locations and the LC9 packs a good punch for a sub-compact CC gun. I trust my life to it!
I don't have any problem shooting 100 shots at a time out of it, but it will never be considered a top "range" gun.
OBTW, zero issues so far.
