I have a PX4 Storm D variant and it has unexpectedly become my first choice amongst all others (Glock, M&P9, Sig, etc...). It has a double action only trigger group that, even though is long and (fairly) heavy with no trigger reset, it is good enough to put all the rounds in the lighter colored rings of the blue and green Marsians. I bought it with no expectations that it would be the platform of choice for those weekend training seminars so I am very surprised that it has been totally reliable (it is pushed hard) and consistently accurate. Highly recommended!
