Thanks (I think) for the mention Elvis. Still trying to keep on topic, I think that the P7 is more robust than we are giving it credit. Yes a few particular parts tend to fail but remember these three things: First we are talking about high round counts that most firearms never see, Second, the piston or the bushing or the drop catch never prevented my pistols from firing (full auto is still firing), Third one that no one recognizes is that because of the squeeze cock action the P7 gets dry fired many more times than any other semi-auto. So the actual round count is somewhat cloudy.
WRT to the drop catch, my opinion is that the procedure of de-cocking by virtue of releasing the squeeze puts a lot of stress on that safety and I believe hastens its demise.
I was lucky in that in all my P7 shooting I never had any other spring break than the drop catch.
Lastly and to me most important...I did carry and USE a P7 M8 for over 20 years. TSHTF several times and because the P7 did it's job flawlessly, I am typing this.
