Hello. I've not taken a course, but have fired Texas'mandated 50 rnd course of fire for CHL instructors with a P7. No problems whatsoever with heat or whatever it is that worries folks and this was in the summer.
I don't fire my P7 very much as I prefer Brownings, CZs, and 1911s, but have fired more than 50 rounds at a time with no
problems.
Best.
