Just got PT145 Millenium Pro,and no problems with feed or function,EXCEPT when doing rapid fire drills,the mag drops,leaving me with an empty chamber.Seems to be more prevelant with one mag versus the other,but I wonder if my grip on the gun could be the problem.Anyone else have this happen?Perhaps a stiffer mag catch spring would cure it,sure doesn't take much pressure to drop the mag.Ideas??Thanks in advance to anyone sharing their wisdom/experience...
