Advantage Arms 10-round .22LR conversion magazine for Glock 26 and Glock 27 — paired with the Advantage Arms .22LR conversion slide kit, this turns a Glock 26 or 27 into a low-cost rimfire trainer without changing the frame, trigger, or controls.
Polymer-bodied magazine with last-round bolt hold open. Sized to fit the Glock 26/27 magazine well exactly, so it sits flush and drops free under recoil. Requires the AA conversion slide kit (sold separately) — this magazine will not function with the OEM Glock 9mm or .40 S&W slide.
Verify magazine seating before each session — rimfire conversion mags occasionally need a light follower clean to keep the last-round catch working reliably.
