I can't speak foe the 9mm but I own a PX4 in .40 The gun shoots great and I agree it just feels nice. I will say that the stock sights on mine are off a good amount and I plan on replacing them but I have had no issues with the gun with 500 or so rounds down range.
My daughter loves mine. Last time it went to the range with us, I brought 200 rounds of ammo. Ran one mag through our 9mm PX4 and handed it to may daughter. I was still sighting in a new rifle when she came over complaining that she was out of ammo!!!!
Nice pistol, with the three backstraps that came with it, one is sure to fit you. They are very usually accurate and very reliable.
Own the Compact version in 9mm. No problems at all. Smooth shooter. It is wide, but feels solid in the hand. Has not been a problem being accurate with the short barrel.
I have a OD green PX4 9mm that is my current home defense pistol. I have over 1000 rounds through mine with no problems. In my opinion it is one of the best polymer pistols on the market.
I has the sub compact 9mm and am very happy with it. Easy to shoot, fits my hand well with the largest back strap. Galco needs to make an ankle holster for it.
Bought the sub compact one for my wife. She loves it and I've been shooting it lately too. Very nice feel in the hand and love the trigger feel. Shot about 500 rounds with no issue.
