Best Glock Magazine Extensions & Basepads 2026 (Competition & Carry)

Best Glock Magazine Extensions & Basepads

Ranked from flush carry floorplates to competition +5/+6 basepads, with the Gen fit and magwell pairing each one wants.

Carry +1/+2 vs Competition +5/+6: The Decision Framework

The right extension is decided by where the gun lives, not by round count. A carry gun wants the shortest floorplate that fixes your grip; a competition gun wants the most capacity its division will allow. Carry extensions add 0 to 2 rounds and protect concealment. Competition basepads add 4 to 6 rounds and ignore concealment entirely. The table below sorts the picks by the use case you are actually buying for.

Flush-Fit & Carry Options

For carry, the best magazine extension is the one that fixes your grip without printing. The Vickers Tactical floorplate is the duty pick: it adds no length and no rounds, and the flared, grooved scallops give the support hand a positive surface to rip a swollen or fouled magazine free under stress. On the single-stack G43, the Pearce +1 converts the pinky-tuck floorplate into a full three-finger hold and adds a round for under ten dollars; the Taran +2 trades some concealment for two rounds on a one-piece billet aluminum floorplate that strips with a tool-less push pin when the G43 sees range or competition time. The subcompact G26 gets the same grip fix from the Pearce PG-G526, which kills the pinky tuck on the flush 10-round mag with no added round.

The MagGuts +2 kit is the outlier and the only true capacity upgrade that keeps the carry profile. It swaps the spring and follower so two more rounds fit inside the existing tube, turning a flush G26 10-round mag into a 12-rounder with the concealment footprint untouched. Plan on a break-in and live-fire test before you trust it for carry, since the stiffer replacement spring makes seating the last two rounds harder. Platform-specific grip and capacity work for these guns also lives in the Glock 26 upgrade guide and the Glock 43 upgrade guide.

Competition Basepads: TTI, Henning, Dawson

For competition, the best basepad is the most capacity your division allows on a factory tube that still seats and feeds clean. All four picks here run on full-size Glock tubes, the G17 and G34 in 9mm and the G22 and G35 in .40 S&W. The Dawson Precision tool-less +5 is the range default: the slide-off locking plate strips for cleaning in a second, a factory G17 tube hits 22 rounds inside the 141.25mm gauge, and it is common enough on a USPSA range that springs and parts are trivial to source. The TTI Firepower +6 is the capacity king, pushing the same tube to 23 rounds for Carry Optics, with an aluminum body that adds seating weight to drop reloads home harder.

When your division caps magazine length, the shorter TTI +3/+4 passes the 141.25mm gauge at 21 rounds without the Firepower's overhang. The Henning +6 is the alternative +6 to the Firepower: it hits 23 rounds on a factory G17 tube, measures 141.25mm assembled so it passes the gauge, and ships with a tuned extended spring matched to the longer tube, which is the reliability edge Carry Optics and Limited Optics shooters pay the premium for. One shared tradeoff across all of them: an aluminum floorplate wears the polymer Glock mag catch faster than the OEM floorplate over a high round count, so inspect the catch on a competition gun the way you would any wear part. A full competition build pairs these tubes with optics and a trigger; the Glock 34 upgrade guide covers the rest of the gun.

Gen 3/4/5/6 Fit Notes

Glock magazine basepads fit every generation, because the double-stack magazine body and its floorplate interface are shared from Gen 3 through Gen 6. Gen 5 added an orange follower and an extended floorplate lip, but the tube geometry aftermarket basepads index on did not change, so a basepad sized for the full-size tube generally carries across generations. Not every maker lists Gen 6 explicitly yet, so confirm Gen 6 fit on the product page before ordering. The trigger-housing change that makes Gen 6 aftermarket triggers a fitment headache does not touch the magazine. The only real caveat is the Gen 5 forward floorplate lip and the left-hand mag release; the matrix below spells out what to watch per generation.

Magwell Pairing: When a Basepad Alone Isn't Enough

A flared magwell is the upgrade that turns a competition basepad into a measurably faster reload, for duty, range, and the divisions that allow it. Mind the division line first: USPSA Production and Carry Optics prohibit aftermarket external magwells, so the TTI Carry Magwell is a Limited, Limited Optics, Open, duty, or range upgrade, not a Carry Optics or Production one. Where it is legal, it funnels the magazine into the grip so the mag seats even when your alignment is off under speed, and at 0.9 oz of billet aluminum it adds almost no weight. It is a system, not a standalone part: the magwell will not let a bare OEM floorplate seat cleanly, so every magazine you run through it needs a competition basepad on the bottom. That is the payoff loop, a basepad gives you rounds and a square leading edge, the magwell gives that square edge a funnel to find the grip.

Fitment is narrow. The TTI Carry Magwell is Gen 5 full-size only (G17, G34, G22, G35, G45); it does not fit the G19, any Gen 1-4 frame, the .45 large frame, or a Poly80. It will not work with a backstrap installed and will not seat on grips stippled to the bottom. If your gun clears those checks, it is the lower-profile, carry-capable alternative to TTI's full Competition Lightning magwell.
