I've owned a German police surplus P7M8 a few years ago, and Trevor is right, the trigger and accuracy of the P7 is not as good as claimed, the bluing starts rusting in your hands quick(your hands smell like rust after shooting it), fire 3 mags rapid fire and the trigger guard will burn you and you will have to take a 10 minute break to wait for the gun to cool, the recoil reduction of the messy gas system is overrated.
In tactical use, are you supposed to squeezecock as soon as you unholster? Like in a house clearing situation? Then you are walking around unknown targets with a cocked and relatively light trigger(We don't recomend it wiith revolvers). Or uncocked in your hand, then you will be walking around with a really light grip on the pistol, someone can just lightly tap the pistol out of your hand. I could never figure that out.
All that said, it is the coolest looking pistol...still after all these years. Great show-off gun at the range. I like the squeezecocker doubling as a slide release, very easy to use, and no extra buttons to find or slide to reach. As much as I had hopes for the P7 when buying it(it was still expensive, used and all), in almost every way the lowly Glock 26 did much better. Oh, another good thing about the P7, you can sell it again at a good price!
