Congrats on the new P10C! I need to pick up a couple of spare mags for mine. The slide release will become easier over time. I have just over 300 rounds through mine and the slide release is now no different than any of my other pistols. The trigger on these is really nice. Nicer than any of my tuned Glocks are. I can't wait to see how this gun feels at the 2k round mark.
