A GLOCK-compatible frame weight is a precision-machined accessory that attaches to the front of your GLOCK pistol frame to add mass below the barrel. The added weight lowers the center of gravity, reduces felt recoil, and dampens muzzle flip — giving you faster, more accurate follow-up shots without modifying the slide or any reciprocating components.
Unlike slide weights or compensators, a frame weight adds non-reciprocating mass. That means your cycling reliability stays completely intact while you get the full benefit of a heavier, more stable platform. It's one of the most effective legal modifications for competition shooting and everyday carry practice.
The JRC Frame Weight System is made in the USA by a licensed FFL manufacturer in Georgia — precision-machined, available in FDE and Armor Black, and designed to fit most standard and compact GLOCK frames right out of the box.

Most GLOCK-compatible frame weights on the market add bulk to the slide or require permanent modifications. The JRC design adds mass exactly where it matters most — without touching your trigger or cycling components.
Weight is added to the frame only — not the slide. Your cycling mass stays the same, so reliability is unaffected while felt recoil drops noticeably.
Available in Flat Dark Earth (FDE) and Armor Black to match your existing GLOCK color scheme. Both finishes are durable and purpose-built for range use.

The JRC Frame Weight System is compatible with most GLOCK pistols chambered in 9mm, .40 S&W, .357 SIG, 10mm Auto, and .45 ACP — including the GLOCK G17, GLOCK G34, GLOCK G22, GLOCK G23, GLOCK G35, and other full and compact frame models.
The JRC Frame Weight System is available in FDE (Flat Dark Earth) and Armor Black. Both are durable finishes designed to match popular GLOCK configurations.
No. The weight is added to the frame only — not to the slide or any reciprocating components. Your trigger pull and cycling remain completely unchanged.
Frame weights are generally permitted in USPSA Production, Carry Optics, and Limited divisions, as well as IDPA Stock Service Pistol and Enhanced Service Pistol divisions, as long as the pistol still fits within required box dimensions. Always verify with your specific match director before competing.

"I've been shooting GLOCK pistols for years and this frame weight is a game changer. The FDE finish matches my setup perfectly and the recoil reduction is immediately noticeable. Precision machined, fits tight, ships fast. JRC Guns knows what they're doing."
"Picked up the Armor Black finish for my GLOCK G17. Install was straightforward and the weight difference is immediately noticeable at the range. Muzzle flip is way down. Quality machining — this thing is solid."
"Ordered the FDE for my competition GLOCK G34. Shipped fast from Georgia, packaged well. The added frame weight makes a real difference on follow-up shots. Highly recommend for anyone running a GLOCK pistol in competition."
"Bought the Armor Black for my GLOCK G22. The fit is tight — no rattle, no slop. You can feel the difference in balance the moment you pick the gun up. Recoil is noticeably softer and I'm back on target faster. Worth every penny for a range gun."
"I was skeptical at first — didn't think a frame weight would make that big a difference. I was wrong. The gun sits flatter on every shot and my split times dropped noticeably in my first session. Machining quality is excellent. Ships fast from Georgia. Highly recommend."
"Picked up the FDE for my GLOCK G35 competition build. The color match is great and the weight distribution is exactly what I needed. Paired with my magwell, this setup is dialed in. JRC makes quality stuff — I'll be back for more accessories."
"New shooter here — bought this on the recommendation of my instructor to help manage recoil while I'm building fundamentals. It absolutely works. The gun is easier to control and I'm not developing a flinch. Great product, fast shipping, well packaged."
