So I was at the range today with my g26 with 2 factory mags and had a few problems. I have put around 400 rounds through each mag. For some reason on a few different attempts I couldn't get the full 10 rounds in the mag I would look in the sight window in the back and it would show a tenth round was in but nothing in the 9 spot. What I believe happened is that the rounds were not double stacking the first couple I put in the magazine. I would then unload the mag and only nine rounds come out. So I know I wasn't trying to put 11 rounds in the magazine. Even when I used the tool that I got with my magazines it would not load the tenth round. I would push down the the tool but only the primer end of the round would go down. The nose or bullet end would not go down even enough to get the last round in. Sorry if this was extremely confusing. Lol. On a side not I have not cleaned or lubed my mags since new only had the gun for about a month. Not sure how necessary that is to do though.
