Some weeks ago I bought a new M&P CORE in 9mm for an upcoming defensive handgun class at Front Sight in NV. I spent another $400 for a Leupold red dot sight and close to another $100 for a Blade Tech holster and mag holder set with extras. However, I won't be able to take my four figure investment to Front Site because they require each student to have THREE magazines. The pistol comes with two, but I've visited numerous gun stores in three states and can't find a spare mag. The shop I purchased the fun from hasn't had any since January of this year. What gives?
