The comment period on a set of tour-only equipment restrictions closes today, October 21, and none of it touches the clubs or balls sold at retail. According to Golf.com, the USGA and R&A are weighing three stricter limits for a Model Local Rule (MLR) that competitions could opt into starting as early as January 2028, covering elite play only. Nothing is finalized, and the proposals could still change or get dropped before any of it takes effect.
The first option would lower the margin for error on conforming golf balls. Per Golf.com's reporting, the current overall distance limit is 317.0 yards (290m), with a 3-yard (2.7m) tolerance built into testing to account for normal variation between labs. The MLR would remove that tolerance for tour-only play, holding balls to the hard 317.0-yard (290m) number rather than letting them test up to 320 yards (293m) and still pass.
The second applies the same idea to drivers. Per Golf.com's reporting, the current characteristic time (CT) limit comes from a pendulum test: a test pendulum strikes the clubface, and the contact time between pendulum and face is used as a proxy for how springy, or "hot," the face is. That limit sits at 239 microseconds, with an 18-microsecond allowance for testing variance. The proposal would drop that allowance for tour-only competitions, enforcing the 239-microsecond figure directly instead of letting drivers measure up to 257 microseconds and still conform.
The third is a length restriction. Golf.com and EssentiallySports both report that the USGA and R&A are considering a club-length limit below the current 46-inch (117cm) ceiling, for every club except putters. Neither outlet reported a specific new number, so there's no shorter figure attached to this one yet, just the direction of travel.
All three were requested by the PGA Tour and DP World Tour, per EssentiallySports, which is part of why they're structured as an opt-in MLR rather than a blanket rule change. A tour or committee would have to adopt the local rule for it to apply at all, and only to the competitions that adopt it.
The original plan, announced in December 2023, split implementation by level of play: the ball-testing clubhead speed would move from 120 to 125mph, with the 317-yard limit unchanged, for elite play starting in 2028 and recreational play starting in 2030. On June 17, 2026, the USGA and R&A dropped that split entirely and set a single date, January 2030, for every level of play under what's known as the Overall Distance Standard.
The MLR under comment today is a different, later initiative, first detailed in a notice on September 21, 2026, and it runs on its own schedule. It doesn't replace the 2030 change, and adopting it wouldn't alter conformance for anyone outside the tour-only pool it's written for. I'll admit I read "as early as January 2028" with some skepticism: the original 2023 plan also had a firm-sounding date attached to it, and that date already got rewritten once, back in June.
For a weekend golfer or an improver working on their game, nothing changes because of today's deadline. The MLR under comment is written for a tour-only, opt-in pool, not for equipment sold in stores, so whatever happens with the comment period, the driver in your bag and the ball you're playing stay exactly as conforming as they are now.
The 2030 change is a different case, and it does reach you. That ball-testing update, already locked in back in June, applies to every level of play, recreational included, not just the tour. January 2030, not January 2028, is the date that eventually touches recreational golfers, and it's already decided; today's comment period isn't what determines it.
Data-backed reviews and advice that works. No brand spin.
