Both are fun guns, but after receiving my Pp750, and smoothing out the kinks, the winner is...... PP750, at least for me. I like the Maurader Pistol so much I have two of them, and up until a month ago they were my favorite carbine/pistol out of a dozen rifles & pistols.
The Pp750 does require some " LOVE" right out of the box, but everything is easily fixable, and well documented on several forums. If I can (you can) turn a "rough around the edges" production gun into a smooth, well functioning gem with "caveman" tools only. I couldn't be happier with the results . For 35 yards and less it shines. I'm using a red dot right now, with old man eyes, so it's probably better than I think it is.
I'm having Cataract surgery next month with Panoptic multifocal lenses. I guess I'll find out if the that Pp750 is as good as I think, or maybe those 5 shot groups are just "blending" into an illusion of one big hole. He he
