Original, perfect magazine. I received the version with "-01" at the end of the number. It looks the same as the previous ones, but apparently there are differences: Main changes in the "-01" version: 1. Magazine lip geometry: In the "-01" version, the lips holding the cartridge were slightly adjusted. This change is intended to ensure more reliable feeding into the chamber, especially when using Hollow Point (JHP) or heavier bullets. 2. Catch cut-out: The profile of the cut-out where the magazine catch engages has been improved. This ensures a more secure fit of the magazine in the well and eliminates micro-movements that could cause malfunctions (so-called failure to feed). 3. Polymer reinforcement: In newer batches (2025/2026), it was noticed that the polymer housing is slightly stiffer, which prevents the magazine from “swelling” when loaded fully with 10 rounds, and makes it easier for it to drop freely from the well during magazine changes. Highly recommended.
