my brain can do this...I suspect yours can too
Try it under pressure and see. You'd be surprised what your brain will and won't do under pressure. There are a lot of things that are dead simple when there's nothing going on that become extremely difficult when the world starts blowing up. Remembering to squeeze the cocker- an action that you do not have to do on any other gun- is something that might be forgotten when everything starts going down the drain.
I'm not advocating against the P7. Heck, it might be the best defensive single stack 9mm ever. You just need to make sure that the manual of arms is second nature if you carry it defensively. Just assuming you will do it right in a pinch won't cut it.
War Story: I learned to shoot on a BHP. Drawing and flicking that safety down was second nature to me. Fast forward to my police academy, where we had 4506s (decock/safety was up to fire, down for decock/safe). I go through the entire month of firearms training with no snags, right up to the point where we did a high stress course.
I run up to the barricade, draw my 4506, and as it is coming up I flip that safety down to decock/safe, and then wonder why my trigger has no resistance and there's no loud bang. The drill sgt/RO then proceeded to (kindly and gently) inquire what in the
I thought I was doing.
Yeah, "I thought I was shooting a Browning Hi-Power" didn't cut it then, and wouldn't have cut it on the street, either. Train until the manual of arms is second nature, and don't make things more complex than they need to be.
