LOK Grips Review: The Best Upgrade for Your Competition Gun

If you shoot a CZ competitively and haven’t upgraded your grips yet, you’re leaving performance on the table. Here’s why LOK Grips are the go-to choice for serious competitors — and the unconventional setup I run on both my USPSA and IDPA guns.

The Problem with Stock CZ Shadow 2 Grips

Let’s be real — the CZ Shadow 2 ships with perfectly functional factory grips. They’re aluminum, they’re decent, and for a casual shooter they do the job. But once you start running this gun in competition, the limitations show up fast. The stock panels are relatively flat, the texture is mild, and there’s no accommodation for the fact that your hands are not the same size or shape as the person next to you on the line.

The stock aluminum grips measure the total grip width at 1.135 inches across the gun. That’s a one-size-fits-all solution in a sport where your grip interface is one of the most critical variables you control. For competitive shooters in USPSA Limited Optics, IDPA CCP, or any other division where the CZ platform dominates, that’s a problem worth solving.

LOK Grips is the solution most serious CZ competitors land on — and after running them on two different guns across two different disciplines, I can tell you why.

What LOK Grips Actually Are

LOK Grips is a Michigan-based company that specializes in precision aftermarket grip panels for competition handguns. Their CZ Shadow 2 lineup alone covers more configurations than most manufacturers cover for their entire catalog — different profiles, textures, materials, and sizes, all designed to let you build the grip that actually fits your hand and your sport.

Materials: G10 vs. Aluminum vs. Brass

LOK offers three core materials for the Shadow 2:

G10 (Phenolic G10) — This is their most popular option and what most competitors run. G10 is a fiberglass laminate that’s roughly half the weight of aluminum but nearly as strong. The key advantage over cheaper polymer or acrylic grips is that G10 won’t crack or shatter under hard use — and the color is dyed into the material, so scratches don’t show through. G10 grips come in at about 53 grams, compared to 58 grams for the stock aluminum panels. Lighter, grippier, and more durable than budget options.

Aluminum (6061) — CNC machined from billet aluminum and anodized in multiple colors. These run heavier than G10 but add mass low in the gun, which some shooters prefer for recoil management. The GridLOK texture pattern is the standard on aluminum versions. Full-size aluminum palm swells weigh in around 2.872 oz. More expensive than G10 — typically $84.95+ — but a premium feel and finish.

Brass — The heaviest option, running up to $125–$135. Brass grips shift weight distribution significantly and are favored by shooters who want every bit of front/bottom mass they can get for muzzle control. IPSC and USPSA legal where allowed by division rules.

Profile Options: Thin vs. Standard vs. Palm Swell

This is where LOK’s lineup gets genuinely interesting — and where the right choice depends on your hand size and shooting style.

Thin — Narrower than stock. Designed for shooters with smaller hands, or anyone who needs their thumb to reach controls without shifting their grip.

Standard — Matches approximately the stock profile with improved texture.

Palm Swell — Thicker through the midsection of the grip panel, filling in the natural cup of your palm. The palm swell version pushes total grip width to 1.475 inches at the peak — a significant jump from the stock 1.135 inches. LOK also trims these thin at the top to accommodate the Shadow 2’s characteristic high grip geometry toward the barrel axis.

Texture Patterns

LOK offers a range of textures under names like Bogies, GridLOK, Ridgebacks, Roughnecks, Jaws, and Checkered. Here’s the quick breakdown:

• Bogies — Dimple texture, very aggressive, excellent in wet or sweaty conditions
• GridLOK — Classic grid pattern, aggressive and consistent across the panel
• Ridgebacks — Ridge-style modern design, aggressive lateral grip
• Roughnecks — Their most aggressive checkering, big and sharp
• Checkered — Fine checkering, described as similar to sandpaper in feel
• Jaws — Serrated texture, available in aluminum and brass

How I Run Them — The Asymmetric Setup

Here’s where my setup gets a little different from what most people do, and it’s worth explaining because it might solve a problem you haven’t thought to solve yet.

I run LOK Grips on two guns: my CZ Shadow 2 in USPSA Limited Optics, and my CZ Shadow 2 Compact in IDPA CCP. On both guns, I run an asymmetric grip configuration — standard panel on the right side, palm swell on the left.  

Here’s why.

Hand size is the driver. My right thumb needs to reach the magazine release without breaking my grip or shifting my hand position. On the CZ Shadow 2, the magazine release sits in a specific spot, and if your grip panels are too thick, you’re either stretching awkwardly or re-gripping to hit the release — neither of which is acceptable when the clock is running. The standard panel on the right keeps the overall grip size within the limits of my thumb reaching the magazine release.

The left side is a completely different story. My support hand needs purchase on the gun. A flat grip panel on the left means my palm has nothing to lock into, which shows up as grip inconsistency under recoil. The palm swell on the left gives my support hand something to actually grip, filling the cup of my palm and creating a locked-in feeling that a flat panel just doesn’t provide.

The result is a gun that fits my specific hands. My right thumb hits the mag release naturally. My left hand is anchored. And the grip stays consistent from the first shot to the last.

This isn’t a common setup because most people don’t think to mix profiles across sides — but LOK Grips makes it easy because they sell panels individually or in a matching set. You’re not forced into a matched pair if a matched pair doesn’t serve your hands.

Real-World Performance: Do They Actually “LOK On”?

The name isn’t marketing fluff. The combination of aggressive texture and proper fit creates a grip that genuinely does not move in your hand under recoil. After running these through USPSA stages — multiple strings, speed reloads, movement — the gun stays exactly where I put it in my hand.

Are there cheaper options? Yes. Plenty of them. You can find polymer grip panels for CZ platforms at a fraction of the price. But cheaper polymer and acrylic grips are prone to cracking under sustained use, and the texture patterns on budget panels tend to wear down faster. G10 doesn’t have that problem.

The fit is also tighter than budget alternatives. LOK machines their panels to CZ’s specifications, and the result is grip panels that sit flush with no rocking or movement. When you’re paying $50–$85 for G10 panels or $85–$135 for aluminum or brass, you’re paying for that precision.

What I’d change: Nothing about the product itself. The only friction in the LOK experience is decision fatigue — their configurator has a lot of options. Give yourself 20 minutes on their site because you will have a hard time deciding between the endless options.

LOK Grips for the CZ Shadow 2 Compact

The Shadow 2 Compact is a similar to its full size.  The Compact lineup includes both carry-length and standard panels length grips to accommodate any use of a magwell .

For IDPA CCP, I run the same asymmetric philosophy on the Shadow 2 Compact as I do on the full-size. The right standard grip and left palm swell still fits in the IDPA CCP box. (Note the stock magazine base pads do not fit in the CCP box so those need to be swapped if you want to shoot a Shadow 2 Compact in CCP)

Bottom Line

LOK Grips delivers exactly what they advertise. The G10 construction is durable, the texture is aggressive without being punishing, and the fit is precise. For CZ Shadow 2 and Shadow 2 Compact shooters competing at any level, they’re the grip upgrade worth making.

The asymmetric standared/palm swell setup I run isn’t for everyone — but if your hand size creates a tension between mag release reach and support hand purchase, it’s a solution that’s worth trying. LOK makes it possible because they sell panels as individual pieces and their lineup covers every profile you’d want to mix.

They cost more than the cheap alternatives. They’re worth it.
