Finding quality magazines for vintage High Standard .22 rimfire pistols can be a real challenge, which is why this Triple-K 490M magazine has become the go-to choice for owners of Sport King, Field King, and Supermatic models. Triple-K Manufacturing has been producing replacement magazines for hard-to-find firearms for decades, and this magazine shows that expertise.
The 490M is built with a steel body and constructed to near-original specifications for late-model High Standard pistols with non-military grip frames. It holds 10 rounds of .22 LR ammunition and features a high-visibility green polymer follower so you can easily see how many rounds you have loaded. The magazine includes a convenient side-facing loading tab that helps compress the follower when loading, making it quicker and easier to fill the mag without sore fingers.
You'll notice the flush-fitting baseplate and overall design closely resemble the original factory magazine, so it looks right at home with your pistol. The magazine comes ready to use, though some owners report minor feed lip tuning may improve compatibility with specific guns. It's the kind of practical accessory that gets regular use at the range or while plinking, and it works well for sport shooting or casual target practice.
This 490M is specifically designed for High Standard Sport King, Field King, and Supermatic models with late-model non-military grip frames. It fits most models produced from the 1950s onward, but compatibility can vary depending on your specific pistol. Some owners have reported needing minor feed lip adjustments for optimal function.
The bright green polymer follower makes it easy to see at a glance how many rounds remain loaded in the magazine. Combined with the side viewing slot, you can quickly check your ammunition count without removing the magazine from your pistol.
Yes, Triple-K manufactures their magazines in the United States. They've been producing replacement magazines for vintage and hard-to-find firearms for over 70 years and are known for their quality standards and attention to detail.
The loading tab is designed to help you press down the magazine follower while loading rounds, reducing hand fatigue and making the loading process quicker and more comfortable. It's especially helpful when loading the magazine to full capacity.
The 490M is engineered to closely match the appearance and fit of original High Standard magazines, featuring a flush-fitting baseplate and period-correct design. Most owners note it looks virtually indistinguishable from the original except for minor marking differences.
