Hey ya'll. I'm a first time gun owner who bought a M&P 40. I paid $100 bucks for a one on one with an instructor. It was informative. Learned about site picture and trigger control. I have been to the range three times. Cleaned and lubed after each shoot. Had a little trouble with Atlanta Arms ammo. The slide wouldn't lock back after last shot three times. I plan on carrying my gat and using for home defense.
