ProMag Industries® Ruger® LCP® II .22 LR Extended Magazine – 10 Rounds – Blued Steel – RUG 27
The ProMag Industries® Ruger® LCP® II .22 LR 10-Round Extended Magazine (RUG 27) is a high-efficiency, range-ready rimfire feeding module precision-engineered to maximize training volume, enhance handling comfort, and ensure consistent cartridge tracking. While flush-fit rimfire magazines can restrict grip real estate on subcompact frames—frequently leaving your pinky finger dangling without leverage and forcing tedious, frequent reload loops during target drills—the ProMag extended configuration thoroughly optimizes your layout. This specialized feeding asset (708279017353) pairs a rugged steel shell with an integrated grip extension, serving as an exceptional secondary magazine option for high-volume plinkers, competitive training courses, and everyday carry transitions.
The structural foundation of this replacement magazine is precision-stamped from heavy-gauge, heat-treated carbon steel to protect the primary body feed paths from shifting or crushing under hard retention impacts. Treated with a traditional, slick Blued / Black Oxide finish, the metal core resists corrosive salt, holster wear, and cleaning chemical splash over long range sessions. The defining technical edge of the RUG 27 blueprint is its specialized **extended polymer base sleeve**. This ergonomically sculpted grip cap bridges the empty space below the short LCP II frame, creating a comfortable, continuous handling surface that drastically reduces muzzle rise and provides small pocket pistols the solid ergonomics of a mid-sized rimfire handgun.
The internal mechanical timing of this 10-round load relies on a smooth-traveling, high-visibility injection-molded polymer follower. Driven upward by a custom-wound, premium heat-treated chrome silicone wire spring, the internal stack maintains continuous, linear upward pressure without binding or nose-diving—an essential design factor when feeding tiny, rimmed .22 Long Rifle rounds through sharp semi-automatic feed angles. Fully backed by ProMag's standard lifetime technical warranty against material defects, this clean-running American-made workhorse delivers affordable, dependable magazine replacement loops for shooters who want to maximize their trigger time.
Includes: (1) ProMag Industries Ruger LCP II .22 LR 10-Round Extended Steel Magazine (Blued Black Finish) with Integrated Grip Extension Baseplate.
*Rimfire Feeding Logic & Ammunition Note: Because .22 LR ammunition utilizes a soft lead projectile and a pronounced rear locking rim, always tap the back spine of the magazine against your palm after loading to ensure the cartridge rims are cleanly stacked in a staggered front-to-back sequence. This simple staging procedure prevents "rim-lock" bypass failures inside narrow subcompact pistol magwells.
Key Features
- Optimized 10-Round Extended Capacity: Provides a full 10-round payload of .22 LR rimfire ammunition, extending target tracking sequences before a forced reload step.
- Integrated Pinky Grip Extension: Contoured polymer sleeve extends down past the short frame heel, giving shooters a complete hand-enclosing purchase for better recoil management.
- Heat-Treated Carbon Steel Housing: Hardened steel body prevents feed lip flexing, structural warping, or side-wall expansion when stored fully loaded over long training cycles.
- Chrome Silicone Wire Internal Spring: Precision-wound internal wire core maintains elastic upward tension, driving clean follower lift and preventing stovepipe or bolt bypass failures.
- Anti-Friction Black Oxide Finish: Clean blued coating streamlines magazine drops out of tight polymer grip wells while masking minor scratches and surface debris.
