I own a glock (that lives in the safe - patterns are for shotguns, not handguns) and I've never gone farther than field stripping it for cleaning after a range session.
I own three P series CZ's.
I don't know what tools are required for Glocks or how hard it is to take one apart (not field stripping, but APART).
I can take the ejector, sear, trigger, trigger bar, hammer w/strut, hammer spring, safeties out of my P series guns without tools. Just push/shove/pull and the parts come out. Same for reinstalling them.
I guess I do need a punch/hammer to remove the extractor?? I don't know, I've not taken one out yet.
For what it's worth, my Glock had more malfunctions than either of my XDMs. Less than either of my M&P's. The only malfunctions my P07 and P09 has had (one each) was due to my lead bullet reloads (one swelled case from bullet being cocked when seated and one failure to chamber from bullet not seated deep enough) not to breaking or feed/extraction issues with good ammo.
And the good parts - the CZ's shoot real groups, not patterns. With the factory barrels, factory sights, factory triggers, factory springs, etc. No extra money spent on the CZ for aftermarket match parts to make them shoot better. I did do some upgrading through the installation of RMRs a couple years ago, but that was to help me (can't see the sights too well these days unless I'm wearing my reading glasses).
If you like a Glock, more power to you, hope it always work out for you (not just the gun working, but the outcome of what you use it for, too.)
