From the results based on the dry cycle testing, the mags can easily handle well over 1,000 rounds. This is because the Menendez 2.0 Mag has been drastically improved over the 1.0 version, and its body is far more rigid. Even though it is susceptible to swelling, the body will perform quite well and not break. The swelling results from the magazine being left loaded for an extended period, putting more strain on the body.
