Keltec P17 Extended Magazine 50 Round

Welcome to the world of high-capacity shooting, where the KelTec P17 gets a serious upgrade! If you love plinking without constant reloads, the 50-round extended magazine turns this already fun .22 LR pistol into a miniature machine-gun-like experience. It’s perfect for long sessions at the range, pest control, or just making your friends laugh when you keep firing while they fumble with standard mags. The purpose is simple: more fun per trigger pull.

The biggest advantage is obviously the round count. Instead of stopping every ten shots, you can blaze through fifty rounds of cheap .22 ammo without pausing. This is incredibly helpful for new shooters learning trigger control, because you spend more time aiming and less time fumbling. For seasoned shooters, it means faster drills and fewer interruptions. Plus, the P17 is already lightweight, so this extended mag doesn’t ruin the balance—it just adds a satisfying tactical vibe.

Let’s talk creative ideas! Imagine setting up a speed-shooting challenge with friends: who can hit a steel gong fifty times fastest? Or use it for backyard varmint control—a single magazine can clear a dozen pesky squirrels before you even need to reload. For competitive shooters in .22 events, the extended mag is a game-changer for stage transitions where every second counts. You’ll look like an action hero on a budget.

Here’s a pro tip: always load carefully to avoid rimlock. Because .22 LR cartridges have rims that can catch each other, loading the magazine too fast or tilting rounds wrong will cause jams. Take your time stacking them neatly, and you’ll get flawless performance. Also, clean the magazine periodically—grit builds up in the spring channels, causing failures.

When you first insert the 50-round mag, slap it in firmly. The pistol’s release is solid, but a seated magazine ensures reliable feeding. If you’re using it for defense (unlikely with .22, but possible), test a few hundred rounds through the extended mag first to guarantee function. Some P17s prefer a break-in period.

Lastly, don’t over-tighten the magazine’s baseplate if you disassemble for cleaning. It’s plastic, and stripping the screw ruins a good thing. For storage, keep the mag partially loaded to preserve spring tension. With these tips, the KelTec P17 with its 50-round wonder is the ultimate plinking companion—more shooting, less reloading, all smiles.
