Generally, HP triggers suck - and this is pretty well known.
You know, this is one of those things that is quite subjective. Trigger quality also has a great tendency to vary from pistol to pistol. While I agree the Hi Power trigger in most cases is inferior to a tuned 1911 and/or an OTB CZ, I think you have to consider it's original intent; i.e. a military service pistol. As you are no doubt aware, to this day with the M16/M4, military leaders are not disposed to send troops off to war with a firearm possessing a "hair trigger." As a shooter who values accuracy, I would prefer to have a good trigger on anything I shoot. On the other hand, as a firearms instructor who has trained many inexperienced shooters, the idea of arming someone with a firearm that has a light trigger, giving that person a minimal amount of training, and then dropping him/her into a high stress environment, sounds rather imprudent.
If you're looking for a match pistol, then I agree, the CZ is going to be more competitive right out of the box. It also allows for greater customization. On the other hand, for a battle pistol that's going to be dragged through "Lord-knows-what", and then asked to perform, I think the Hi Power performs very well. It's heavier trigger may even be beneficial in that it will help prevent inadvertent shots from being squeezed off in a "startle-response." Keep in mid the fact that, in military applications, the pistol is not a primary weapon. It's intent is to provide personal protection at close range. In such a context, the Hi Power's trigger is certainly adequate. As always, the determining factor in effective weapon performance lies in a shooters training and preparation.
