I have had my Mini for about 3 weeks now but still haven't had the time to get to the range or desert to shoot it. While monkeying around with it getting myself familiar with the rifle I noticed that most of the mags, factory Ruger and off brand, 10 rounds can be a bit difficult to insert as well as pull from the mag well when releasing. Is this tight fit something that will "loosen up" with use over time? I don't expect the mag to drop when I push the button but it takes some force to insert and extract. What say you. Thanks.
