CZ75, HK USP and the GLOCK
Here is my opinion from shooting them:
Fit and finish:
1. HK USP (very good overall)
2. Glock (good overall)
3. CZ (excellent exterior, poor interior; average overall). Exterior finish is flawless on my CZs, as good as Sig and in some cases better. However.....the biggest problem on my CZs are TONS of interior tool marks, and really bad interior metal work. Doesn't affect function, since this is in non-critical areas, but it certainly should be better IMO. Funny how the same company IMO does great work on the exterior, but very sloppy interior work (IMO).
Accuracy (subjective):
1. CZ 75
2. HK
3. Glock
Ergonomics (subjective):
1. CZ 75 (top notch)
2. HK (mediocre)
3. Glock (mediocre)
Trigger (subjective)
1. CZ (great SA, fair DA)
2. HK (DA and SA seem to be acceptable, not good though)
3. Glock (mediocre "safe-action"
Durability (my best guess):
1. Glock
2. HK
3. CZ
Overall shooter (subjective):
1. CZ 75 (best .40 I've shot and owned, including Sigs, etc)
2. HK (very good, but not as comfortable as the CZ)
3. Glock (respectable)
Other comments, all three are reliable in general, but the CZ seems less tolerant of being dirty than Glock or HK. When I had the CZ 75B in .40, it was 100 percent reliable when clean....but if not cleaned after a 200 round day reliability would fall a bit.
