I've owned a few NIB(new) Beretta model firearms in the last 18 years and I used a M9/92F in the US Army for 18mo as a lower-enlisted soldier on active duty.
I'd pick a PX4 series C format(constant action). This smooth DA only hammer fired pistol would do very well as a compact, concealed pistol.
I only sold my PX4 C 9x19mm pistol due to major $$$ problems in 2009.
A ambi-control Compact PX4 is a good value and can protect you, but if I had to pick 1 firearm, I'd buy a NIB PX4 C model.
