I had a Grand Power P11, but it was before the MK 12, maybe a MK 7? I don't recall at the moment but have paperwork here somewhere. I wanted a MK12 as soon as I learned of them, and sold mine to the first person that knew what it was.
Then life happened and without a local GP dealer, I let the idea slip away. But this thread is rekindling my "want". They are very well made, and have a very soft shooting rotating barrel, similar to the Beretta PX4 line.
For a poly framed gun, it's one of the few I would buy again (PX4 included, but I kept the last one). I have an FNX40, the 9mm PX4, a Shield 45, ........ well, that's it I think for poly frame guns. But I will find a MK12 or whatever version they sell now. Mine was soft shooting as I said, accurate and reliable after the first 50 or so rounds, only 1 or 2 stoppages early on.
Great guns, and thanks for reminding what I was doing. LOL! (find a GP, find a GP, find a GP...)
