My full size PX4 type C in 9mm came in today. I took it home, cleaned it, greased the barrel, and went to the range. Put two hundred rounds through it, everything from really old junk stuff to 147 grain HP. Gun ran great. I found the federal 115 grain fmj to shoot about an inch low but the 147 grain sub sonic shot POA. Thought this was strange. This gun is on par or more accurate then my Sig. The gun grease made a mess. I cleaned it off after the range and cleaned and lubed with CLP. I may try some mill tech next time. I had the larger backstrap on at the range but changed back to the med. The gun came with two 17 round mags, three backstraps and a mag loader which is needed with these mags. Very happy with the purchase. I haven't owned a 9mm in a long time and the lack of recoil and muzzle blast was a downer but I'll get use to the ammo price.
