A few guys pointed out that they like the mag release, and I have to echo that; ambidextrous and it makes a lot of sense. I find myself using both my thumb and index finger to push it down a lot of the time, and this gives a very positive release. It's also nice that if one finger misses the release or can't get to it, the other one is there.
I also like the decocker/safety and the ability to carry cocked and locked.
DMgangl, thanks for the vote of confidence regarding the rental specimens continuing to function. It's nice to hear positive stories like that!
JLS, I'm with ya; I'd love to own a P7 some day, they are nice!
Sarguy, I love you how described the German designers as being obsessive/compulsive, lol! When it comes to weapons, they really are!
Thanks to everyone else for the positive comments.
