This is a single-stack, 10-round detachable magazine built specifically for the Glock 42 in .380 ACP. It gives you a meaningful capacity boost over the factory 6-round magazines that come standard with the Glock 42 without the bulk of larger pistol mags.
The magazine body is made from proprietary DuPont Zytel polymer, a material known for impact resistance and longevity in magazine applications. A full-length steel internal insert stamped and welded like factory construction provides the structural support needed to maintain feed lip rigidity through hundreds of load cycles. The injection-molded polycarbonate follower rides on heat-treated chrome silicon wire that's precision wound for consistent spring tension.
The extended length of this mag gives your Glock 42 better grip real estate, which many find more comfortable for sustained shooting sessions. Loading takes a bit more effort than some magazines until the spring breaks in around ten-fifteen cycles. The extra four rounds compared to factory mags means fewer manual reloads during practice, which is particularly nice for long range days.
This magazine is manufactured and assembled domestically. ProMag backs every magazine with a lifetime warranty against manufacturer defects, so if something goes wrong with materials or workmanship, replacement is covered.
No, this magazine is designed exclusively for the Glock 42. It will not fit other Glock models like the G43 or G48. Always verify magazine and firearm compatibility before purchasing.
New magazines often have stiff springs, so expect the first ten to fifteen load cycles to require more finger pressure until the spring relaxes. This is normal and doesn't indicate a defect. Loading at a slightly reduced capacity for the first few uses can ease the break-in process.
Full metal jacket rounds and standard ball ammunition typically feed without issues. Some users have reported occasional feeding problems with hollowpoint ammunition depending on overall length and specific magazine unit tolerances, so field testing with your intended loads is recommended before relying on it.
This magazine holds ten rounds versus the factory six-round capacity, giving you four additional shots. The extended length also provides better grip for many shooters. Factory Glock magazines remain the standard for reliability and are generally preferred if capacity isn't a concern.
