I have a P-94 in .40 with a PC4GR that uses the same magazines. I purchased these firearms because I wanted a rifle/pistol combo in the same caliber. Since I am not into revolvers and lever actions, it became a logical choice. The P-94, as others have stated, has a long DA trigger, but the SA is tolerable and the pistol is reliable and rugged. True, it does not win much admiration at the range, but it works without a hitch.
As for the issue of high capacity magazines, the Ruger .40 has 11 in the box for the LEO version, so you don't lose much by sticking with the 10 round kind. As for the 9mm variety, I suggest looking at Gun List and other such publications for advertised specials. Also, some gun shows and shops have a fair share too. They are around.
I suspect many people dislike Rugers due to Bill Ruger's controversial statements about firearm legislation over the years. If anything, Bill Ruger is his own man who does not take fecal displacement from anyone. You can see it in how he runs his business, speaks his mind, and designs his weapons. While I don't always agree with him, I admire his moxie.
