This Triple-K high standard magazine holds 10 rounds of .22 LR and is built for the High Standard Duramatic 100/101 and the broader family of Slant Grip pistols. It fits the Supermatic Citation 104, Field King, Sport King Series 102/103/104, J.C. Higgins 80, Plinker M101, and Sharpshooter M103. Owners of these older rimfire pistols often struggle to find factory magazines, so this US-made replacement fills a real gap for collectors and range shooters who want to keep a Slant Grip High Standard running. It's a straightforward feed device for plinking, small-bore target work, and general practice with .22 LR.
Triple-K builds this magazine with a two-piece folded steel body and spot-welded construction, finished in blued steel. The high standard 22 magazine is cut to close tolerances from high-quality steel, which matters on the Duramatic platform where feed geometry and magazine fit determine whether the pistol cycles cleanly. The tube measures roughly 5 inches, and the magazine is dimensioned around the 6.5-inch barrel configuration common to these guns. Capacity is a full 10 rounds of .22 LR, matching original High Standard specifications for the Slant Grip series. Because these pistols vary across production years, older frames occasionally need minor adjustment to seat a new magazine fully, which is normal for parts serving decades-old firearms.
If you shoot a Slant Grip High Standard, a second or third magazine cuts down on reload time during a range session and keeps a working spare on hand when originals wear out. This high standard duramatic magazine drops into the same pistols that Triple-K lists for the series, so a Duramatic, Field King, or Sport King owner can standardize on one part. We stock replacement feed devices for plenty of legacy .22 pistols alongside this one, so browse our handgun magazines and the wider magazines selection for other rimfire options like the Colt Woodsman 10-round magazine.

It's built to the correct dimensions for the Slant Grip series, but because these pistols span many production years, some older frames may need minor fitting to seat the magazine fully. That's typical for parts serving firearms this old and is easily addressed.
