Also have the Steyr GB and Walther P88 -
Because everyone needs a handgun that uses magazines that cost more than current plastic nines.
I also own a Steyr GB and Walther P88. They are two guns that I still shoot on a regular basis
I really love my P88 with the Nills thumb rest grip installed
Magazines are not too big of an issue for either these firearms. The good folks at KKK have just released magazines for the Steyr GB last year. Like many of the KKK offerings the mag springs were kind of tight and the first round didn't like to feed, but after leaving the Mags loaded for about six months the springs took a set and everything works very nicely now.
The sample magazines that I had did rub at the very bottom as they were inserted into either of my Steyr GB's, however when I looked at my factory magazines they all had rub marks in exactly the same spot so I didn't actually worry about it too much
I have had my Walter P88 for more than three decades now, so magazines were a concern to me at the beginning. One of the things I noticed back then was that the P88 shared a magazine body with the SIG P226 and the Beretta model 92. Obviously the cut out for the magazine catch is in the wrong place on both of these
Since I had access to a mill I set up to cut the new magazine catch notch, I think it took me about 30 minutes to do a dozen magazines
If you do not have access to a mill or a buddy with a machine shop this can easily be done with a Dremel or even hand files
The one thing that I failed to notice at the time was that the SIG and the Beretta have a different spot in the follower to lift the slide hold back. One of the two of them is at the wrong height and will hold the magazine open with a round still in the mag the other one works absolutely flawlessly. I just do not remember which is which right now
