Finally, buying five at once covers a full range day without constantly running back to the bag.Will these 5 Glock Model 21 .45 acp 26 rd New magazines fit my Glock 21?Yes, along with other Glock .45 ACP double-stack models. So these magazines fit the Glock 21, G30, G30S, and G21SF. However, they do NOT fit the Glock 36, G37, or G38 — those use different magazine patterns. Also, these fit Glock-pattern PCCs and carbines chambered in .45 ACP, like the KRISS Vector. Therefore, confirm your specific model before ordering.Do these need any break-in before running full capacity?5 Glock Model 21 .45 acp 26 rd New magazines   Yes, expect some initial stiffness. So like most new extended magazines, these may need several loading and unloading cycles before accepting all 26 rounds easily. Also, the chrome silicon wire spring is intentionally stiff from factory to ensure reliable feeding at full capacity. Therefore, load and unload them a few times before your first range session, and use a magazine loader to make the process easier.How much does the 26-round extension stick out past the grip?5 Glock Model 21 .45 acp 26 rd New magazines   Noticeably, since this is an extended magazine. So the G21’s standard magazine is 13 rounds. A 26-round magazine roughly doubles that length and extends significantly past the grip frame.
