Talk about close. Got a new Sphinx sub today, super accurate. Side by side with my P07 it?s upper looks almost the same except about 1/2? shorter, grip allow just a full grip, about 1/4? difference but just enough for a full grip. Much better than my P10s. No pinching. Nearly same weight, I really hope CZ puts out a smaller P07 and if they made a poly version of the Sphinx sub, that would be the bees?s knees. Lastly, I bought a P07 kadet kit and it is phenomenal, love it.
