Well, i own a P7 M13 too. It cost a lot for me, so i didn't shoot with it yet¡¡. Seriously, the first day i take possesion of it, i went to mi range to shoot. Great was mi surprise when, after maybe 40 or 50 rounds of really rapid fire, i barely could have the pistol in mi hand. I previously know that it went hot after some rounds, but i never believe up to the point that i could't have it in mi hands. But i agree with you that is a wonderful pistol, very fast in action and with a marvelous trigger.
But i really prefer the P9 S. here i have to tell you wich are mi preferences about shooting: i really don't like bulleye shooting. Most of mi shooting is in the 5 to 10 meters range, that is where according stadistics, all shootings ocured. Well, for this type of shooting, mi P-9 S ios incredible. I don't practice from a long time, but two years ago, i can obtain double taps in one or two inch at five meters with .15 seconds split. The lack of recoil is really amazing. But i also know the pistol have it drawbacks. Mine have the recoil buffer broken twice, and the reliability, i thinks due to the magazines, is not 100 %. But i love it. At last, i thinks .15 split is really fast, but remember, i base mi practice in this kind of shooting.
