Not familiar with the PPQ so I had to look it up.
Based on what I read I think a CZ 75 compact may be just what your looking for. I use a CZ PCR which is an alloy version with a decoker. the 75 compact is all steel, 14 round, DA/SA with a safety. Both of my CZ's, the other is a full size, have been 100% reliable and I'm amazed at the accuracy of the PCR. As I understand it Canik offers a alloy clone of the 75 compact. By the way, safest way to carry any Semi is empty chamber, loaded magazine, that's what I like about them over say a wheel gun.
