What the 2026 rules actually change

On January 1, 2026, the ISSF updated its general regulations for pistol grip design in 10m air pistol and 25m sport pistol events. The underlying principle is not new: the grip must support only the hand, and the wrist must remain visibly free at all times. What changed is the specificity. The 2026 rulebook plugs gaps that allowed some grip geometries to pass inspection while still providing indirect wrist support through leverage or contour.

If you are wondering whether this affects you, the short answer is: probably yes, at least a little. Most production grips from the last few years were designed around the old tolerances. The good news is that the adjustments are usually small.

The three areas the ISSF tightened are the rear web-of-hand contour, the thumb rest shape, and the palm rest angle. Let's walk through each one.

The rear "horn" above the web of your hand

The rear upper portion of the grip, the part that sits between your thumb and index finger when you hold the pistol, is now subject to a length limit and an angle requirement. Under the 2026 rules this section (sometimes called the "horn") may extend no more than 40 mm rearward on 10m air pistols, or 30 mm on 25m sport pistols. Additionally, the upper surface of this section must angle downward at 45° or more relative to the barrel axis.

In plain language, if you set your pistol on a table and look at it from the side, the material behind the rear sight that fills the web of your hand cannot stretch back too far, and it must slope down sharply rather than forming a shelf.

Why does this matter? A long, flat upper surface effectively braces the wrist by filling the gap between hand and forearm. That is exactly the kind of passive mechanical advantage the ISSF wants to eliminate. By limiting the length and requiring a steep downward angle, the grip can still provide a comfortable contact surface for the web of your hand without acting as a wrist lock.

Some grips on the market prior to 2026 had a gently sloping or nearly horizontal upper surface extending 50 mm or more behind the rear sight. Those will need material removed. A competent grip fitter can usually do this in under an hour with a bench sander and some finishing work.

Thumb rest curvature changes

The thumb rest is another area that received closer attention. The 2026 rules state that the outer edge of the thumb rest must angle downward. Upward curvature, which could trap the thumb and restrict its natural positioning, is prohibited.

This is a subtle but intentional change. Some grip designs incorporated a slight upward lip on the thumb rest to give the shooter a more secure feeling of purchase. The ISSF considers this a form of hand encirclement: if the thumb cannot freely lift away from the grip, the shooter is not fully controlling the pistol through active muscle effort.

For most shooters, this will not require a visible change to their grip. If your thumb rest has a flat top or already angles downward, you are fine. If it has a raised edge, a few minutes with a file or Dremel will bring it into compliance.

Palm rest angle requirements

The palm rest, sometimes called the heel rest, is the lower rear portion of the grip that supports the base of your palm. Under the 2026 rules, the trailing (rearward) edge of the palm rest must form an angle of 30° or more relative to the perpendicular of the rest surface.

Think of it this way: if you look at the palm rest from the side, the back edge should not be cut straight up and down. It needs to angle rearward, so the hand can naturally slide or shift without getting caught on a vertical wall.

This requirement ties back to the same principle as the thumb rest. A vertical trailing edge on the palm rest can act as a shelf that locks the hand into a fixed position. By requiring the edge to angle away, the ISSF ensures the shooter is actively maintaining their grip rather than relying on the grip geometry to hold their hand in place.

How to check your own grip

You do not need any special tools to get a rough idea of whether your grip will pass. Here is a practical checklist you can run through at home.

Web-of-hand horn: Place a ruler along the top of the grip, starting from the rear sight and extending backward along the upper surface that contacts your hand web. If it extends beyond 40 mm (10m) or 30 mm (25m), you likely need material removed. Then check the slope: that surface should drop away at a noticeable angle, not run roughly horizontal.

Thumb rest: Look at the outer edge of the thumb rest, the part your thumb tip touches or rests near. Does it curve or angle upward? If yes, it needs to be filed down so the edge angles down instead.

Palm rest trailing edge: Look at the back edge of the palm rest. Is it a near-vertical wall? If so, it needs to be angled rearward at 30° or more from vertical.

If any of these areas look borderline, the safest move is to bring your pistol to a competition before your first scored event in 2026 and ask equipment control to check it. Most officials would rather help you identify a problem during a pre-event inspection than disqualify you later.

Getting your grip modified

Several options exist for shooters who need to update their grip.

Manufacturer service: Morini, Steyr, Pardini, Feinwerkbau, and other major brands offer grip modification services. Contact your national distributor or the manufacturer directly. Turnaround times vary but are typically two to four weeks, so plan ahead.

Custom grip fitters: Independent grip makers such as Rink-Formgriffe, MEC, and others can assess and modify existing grips. Many attend major competitions and can do modifications on-site. This is often the fastest route if you discover a problem at a competition.

DIY approach: If you are comfortable working with your grip, the modifications are straightforward sanding and shaping. Use a Dremel or bench sander to remove material gradually, check your progress frequently, and finish with fine-grit sandpaper. The risk here is removing too much or creating an uneven surface. If you go this route, practice on a cheap spare grip first if possible.

What these rules mean for new grip buyers

If you are shopping for a new grip in 2026 or later, virtually every major manufacturer has updated their designs to comply. When buying, you can ask the seller to confirm the grip meets the 2026 ISSF specifications. Most reputable dealers will stock compliant stock, but it is worth verifying, especially if you are buying second-hand or from older inventory.

Custom grip makers are well aware of the new rules and will build to the current specifications by default. If you are ordering a fully custom grip, mention that you need it to be 2026-compliant just to be certain.

Other 2026 changes worth knowing

The grip rules are not the only pistol-related update for 2026. A few other changes affect competitors directly.

Live aiming in finals: The ISSF has introduced live aiming visualization technology for 10m air pistol and 25m pistol finals. A small tracking device mounted on the pistol displays real-time aim point data to spectators and broadcasters. This does not give athletes any feedback; it is a presentation tool only. Shooters do not need to buy or attach anything themselves, as the ISSF provides the tracking equipment at the competition.

Eight finalists in 25m rapid fire pistol: The number of finalists increased from six to eight, matching all other individual ISSF events. This is a format change only; qualification scoring and shot counts remain the same.

Mixed team restructuring: All mixed team events (10m air rifle, 10m air pistol, and trap) now use a single-elimination bracket format with four teams competing together, replacing the previous separate gold and bronze medal matches.

Once your grip is modified and passes inspection, keep a few things in mind. Equipment control checks happen at every ISSF-sanctioned competition, and officials now have more specific measurement points and tolerances to work with. This means enforcement will be more consistent across different countries and competitions.

If you have your grip modified by a professional, ask them to document what was changed and where material was removed. If an official questions your grip at a future event, being able to explain what was modified and why can help resolve disputes quickly.

For shooters who track their equipment changes alongside their training, TargetLog's armory feature lets you log which grip you are using with each session. That way you can correlate any score changes with equipment modifications. You can download the app and start keeping those records today.
