Give your Glock Gen3 a smoother, softer shooting experience with the Strike Industries Shock Buffer.

Designed to Protect Your Glock Gen3
At the heart of this upgrade is a polyester-based thermoplastic polyurethane barrier that sits between the slide and frame. Every time the slide reciprocates, the Shock Buffer cushions that impact, helping to: Strike Industries+2Primary Arms+2
Reduce metal-to-polymer contact
Cut down on frame and slide wear over high round counts
Make the gun more comfortable to shoot in long range sessions
If you shoot frequently—training, classes, competition, or just regular practice—this tiny part can pay off big in long-term durability.
Softer Recoil & Smoother Cycling
The Strike Industries GSB is engineered to absorb recoil impulse and soften the “slam” as the slide comes to the rear. This helps: Strike Industries+2TLO Outdoors+2
Decrease felt recoil for a more pleasant shooting experience
Reduce shock transmitted to your hands and wrists
Fight muscle fatigue during extended range days
Improve control for quicker, more accurate follow-up shots
Many shooters notice smoother cycling and a more controlled feel with the buffer installed, especially over long strings of fire.
Smart, Secure Design
Strike Industries built the GSB with several thoughtful design details that make it stand out from generic buffers: Strike Industries+2TLO Outdoors+2
Retaining design – Shaped to stay secured on the slide during cycling
Extra cushion knobs – Molded “knobs” increase surface area, adding extra buffer and impact absorption
Engineered hardness (approx. 115°) – Tuned for recoil reduction while preserving reliable operation
All of this comes in a compact, low-profile piece that integrates cleanly into your Glock Gen3 without modification to the pistol itself.
Lightweight & Compact – Zero Bulk Upgrade
Despite its benefits, the Strike Industries Shock Buffer is almost weightless on the gun: GrabAGun+2TLO Outdoors+2
You gain recoil buffering and wear reduction without throwing off the balance of your pistol or making it feel front- or rear-heavy.
