I have one of these, and one of my kids has decided it is his favorite pistol to shoot. It came with only one magazine that holds only 10 rounds. I searched all over the internet, and it appears identical to the 15 round magazines. I saw a "block" that limits the magazine to 10 rounds, so I disassembled my magazine, but it did not contain anything like that. I reassembled it and placed 10 rounds in the magazine. I then applied a lot of force, but, no eleventh round would go into the magazine. Is there anything to look out for when ordering a higher (standard) capacity magazine? I read some good things about a company I had never before heard of, Mec Gear. I don't really want the 30 rounders from WalMart like in the video below [ame]https://www.youtube.com/watch?v=Z1R9DnX4Reo[/ame] I want magazines that fit and function like they came with the gun.
