Good for only 1 extra round - Strike Industries Glock G43X/G48 2 Round Enhanced Magazine Plate

These looked great in the photos and were reasonably priced, so I bought 4. I took one out of the box and thought it looked too small to hold 2 extra rounds, but I figured some mysterious engineering magic would make it happen. Removing the stock base plate required more time and effort than I anticipated, but I finally got it off using an Allen wrench and flathead screwdriver. Installing the Strike Industries base plate was a lot easier. But even after solidly locking it place, there was a noticeable gap between the SI base plate and the bottom of the mag well, as if it wasn't really designed for the pistol. However, the main reason I returned them is because no matter how hard I tried, I could not squeeze more than 1 extra round into the magazine. I even tried with a speed loader, and no luck. So if a +1 round extension is all you need, and you don't mind a 1.5 mm gap, then this product was made for you. Otherwise, keep looking.
