I discovered the hard way (mag fell out in a match) that the Grand Power mag does not click locked when gently inserted. It has to be slapped in.

I am advised that that grip frame is slightly too long and hits the mag pad before the mag is latched. So I took a sheet of sandpaper, ran the pistol base over it and took a bit off the bottom of the frame. The picture shows the before and after. I am guessing I took about only 1 mm off the frame.

Now when I insert a mag it clicks locked.

BTW, I have a K100 and an XTrim. Both have the identical issue. easily fixed. This is a super good pistol and a real bargain at the price.

Yes, it is well known issue, all Grand Power pistols after original K100 and Mk6, including STI GP6, have this problem. I know several ways to fix it, they are all about sanding pistol, mag basepad or drilling bigger latching hole in a mag. I'm using better method for many years, just replace basepad with tanfoglio metal rubber-coated besapads, they are the best! I was posting a picture several years ago.
 
I recall this was fixed on the mK12 pistols. So the latest ones that were on sale shouldn't be affected.

Good idea....got one of the pistols on the way, I'll try and find some baseplates.
Would CZ75 plates work as well?

I tried some Shockbottle base plates on my mags, they fit fine but the retention hole was slightly too small. Was pretty easy to drill out to the proper size. Have since switched to steel base plates from Grand Prairie that Canuck223 helped me with. They were exactly the same dimensions of the original plastic base plates.

On my X-Calibur Mk12, the mag requires a firm insertion, but it does seat properly even when the slide is closed.

If you want to upgrade from the standard plastic base pads, the factory steel basepads work nicely with the Mk12.
If you prefer padded to steel, the rubber bonded CZ base pads work well. For them you either need to get the pad retainer with the smaller hole, or drill them out to .250.

i used these as the factory pads were pinching the meat between my palm and my thumb, made reloads very easy.
