Nothing is a Glock killer. It has such a cult following that even a working Star Trek class Phaser (the original of course, it is way cooler looking) would fail dissuade it's followers from "perfection." Then what do I know, when they came out I though the tupperware gun had no chance of being taken seriously, let alone making it.
You're not alone..Alot of people did'nt think Glock would make it. One reason they did was through rather shrewd marketing..literally giving pistols to law enforcement agency's. This worked, and long story short this helped them get where they're at today.
To me, the P-10 is a product improved g19, it's where Glock should've been had they actually been interested in improving "perfection". It's enough of a improvement that I'll probably put my g19 into semi retirement, as the P-10 does several things better than the Glock does.
1.No brass to the face, this issue surfaced in Glocks about 2009-2010 and Glock has yet to fully resolve it. Both of my g19's needed a Apex extractor to mostly correct the BTF issues I was having.I still get a BTF on occasion, the P-10, OTH, has never done this, CZ it seems, understands that empty brass should'nt eject into the shooter's face, head, left or right shoulder.
2. The grip. With out a doubt the P-10's grip is better, more comfortable than Glock, I actually don't mind the stippling on the backstrap, it works for me, and if later on, I want to tone it down, a few swipes with some sandpaper will do the trick.
3.Accuracy, They're both close when I shot my g19 next to the P-10, shooting rapidly from a draw, at a 5"circle using a timer, accuracy between the two, as well as the times were very close to each other. However, when I was shooting at 2" circles The P-10 was more accurate, and I noticed it was easier to do with the P-10 vs the g19. When shooting the g19 at the same size circles, I had to try alot harder to get hits.
I'll carry my P-10 when it get back from CZUSA, I like it, I like it alot.. but, I'm not getting rid of the Glocks I own either..
