I did. With the Uplula or by giving the mag a few thumps while I was loading. It sounds weird, but it holds more with the grams. I can get 26 of 9mm in with the grams and 25 in as it came. I let it settle overnight, loaded it a bunch of times, and tried factory and reloaded ammo. Its just better with the Grams in every time. Also, I let another person try with the same conclusion. In fact, with the stock internals I was denting cases it was so tight. Just for reference it is a 155 mm for 9/38.
