Strike Industries Shock Recoil Buffer Kit for Glock Gen 3 Models 17, 17L, 18, 19, 20, 21, 22, 23, 24, 24C, 31, 32, 37

If you run a Glock Gen 3 and want to smooth out recoil impulse without replacing the gun, the Strike Industries Shock Recoil Buffer Kit is a straightforward upgrade. This kit installs a polyurethane-based buffer between your slide and frame—the exact spot where metal-on-polymer wear accelerates under heavy shooting. The result is less shock transmitted to your hands, reduced fatigue, and genuinely better control on follow-up shots. It's the kind of modest mod that compounds over thousands of rounds.

Strike Industries engineered this buffer with a retaining design so it stays put on the slide, and built in extra cushion knobs for consistent performance. You get to choose your comfort level: the kit comes in two hardness options, so whether you're running full power loads or managing recoil in a compact frame, there's a setup that fits your shooting style and the gun itself.

Installation is straightforward—no gunsmithing required—and the polyurethane material is durable enough for regular range use and carry. The buffer also extends the life of your frame by absorbing impact that would otherwise accelerate wear between the slide rails and polymer. For Gen 3 Glock shooters looking for an honest recoil management tool that actually works and lasts, this is a solid choice.

Frequently Asked Questions

Will this buffer fit my Glock?

The Strike Industries Shock Recoil Buffer Kit is designed specifically for Glock Gen 3 models 17, 17L, 18, 19, 20, 21, 22, 23, 24, 24C, 31, 32, and 37. It will not fit Gen 4 or Gen 5 Glocks, so verify your generation before ordering.

What's the difference between the two hardness options?

The kit comes in two hardness levels to let you dial in your preferred recoil feel. A softer buffer absorbs more energy and reduces felt recoil more aggressively; a firmer option provides a balance between cushioning and responsiveness. Choose based on your shooting style and load power.

Do I need a gunsmith to install this?

No. The buffer installs without gunsmithing and is designed to secure to the slide with a retaining mechanism. If you're comfortable doing basic maintenance on your Glock, you can handle installation.

Will this slow down my shooting?

Quite the opposite. By reducing shock to your hands and decreasing muscle fatigue, the buffer helps you manage recoil better and get back on target faster for your next shot. It's a performance aid, not a liability.
