Over the weekend had a chance to try this out, the Walther Magnum Pistol

(picture will be added when Google stops googling things up and allows)(Ah, it allowed!)

Magnum meaning .22 Magnum.  Polymer frame, aluminum slide, all the specs on their page.

It's a big pistol, until you pick it up and look at the muzzle you'd think it was a .45.  The one available had a Holosun red dot.  Only had ten rounds to try, so ran the target to ten yards and found
Grip fit the hand nicely.

Very nice trigger.

Grouped very well.

And .22 Mag, in this length barrel, roared and gave a big muzzle flash with almost no recoil.

First impression: if I had the money to buy a new pistol just for fun, this would likely be it.  Time will tell how it stands up, but with aluminum instead of zinc for the slide it'll probably do well.
