Product is made very well, however, it required fitting on my AP5P clone. I had to Dremel the exterior of my mag well to allow this to fit and seat correctly on the firearm. Thank good I had gun blue to clean it up. After getting it on and being happy, the magazine would not lock into place so I had had to Dremel the interior of the Haga mag well it self to make room for the magazine to seat. I have read that others have had this same issue. The rear screw housing does interfere with the full motion of the magazine release paddle which I wish was not the case but the mag does seem to seat and eject so but I may modify the paddle in order to bring the operation back to a more comfortable level for me personally. Again, well made product but there are issues with it that will need to be addressed on the AP5P.
