Before Glock came out with the 43 you could always find Glock fans who would swear that they could pocket carry their G26 just fine. The SCCY is a double stack sub compact I actually did stuff one into the front pocket of my Levis jeans - no holster. I could easily see the entire back of the pistol almost extending above the pocket. It is a tight fit and as you can imagine, it prints very obviously.
There isn't any official definition of what a pocket pistol is but I can tell you that at 5.7" OAL the CPX doesn't come out of your normal front jeans pocket easily or quickly, and this isn't even with a holster which would make things even tighter.
I haven't seen a double-stack handgun in a major caliber that actually works as a pocket-gun for normal jean pockets.
