Callaway Apex 21

The Apex 21s have five times more tungsten weighting than the 19s, with the CG optimally positioned in each iron throughout the set, allowing for more forgiveness on off-center shots. 7-iron testing measured 114.3 mph ball speed + 5,701 rpm spin + 161yd avg carry with a deviation of only plus or minus 3 yards on each shot. Tungsten Energy Core uses up to 50 grams of tungsten per iron to precisely position the Center of Gravity to promote outstanding launch throughout the set, and more forgiveness on off-center shots. Excellent forgiveness, especially for their size. Above-average forgiveness for a players-distance iron — 5x more tungsten than Apex 19 + AI Flash Face Cup per loft + tight ±3yd dispersion + premium category accolades.

Callaway Apex 21 irons will be one of the longest players irons of 2021, with strongly lofted clubs that help the distance aspect. 7-iron 30.5° loft + 161 yards average carry on 7-iron testing. First time A.I. designed Flash Cup Face is in a forged iron — faster ball speeds. Spin was just a little bit higher than previous Apex irons. Above-average distance — strong loft (30.5° 7-iron) + AI Flash Face Cup for high COR + 5x more tungsten launching from low CG + one of the longest 2021 players irons.

Clean, compact golf clubs that fit the look of a players' iron, with a thin topline that frames the ball. Standard Apex 21 irons are best suited to low to mid handicappers. Topline is a little narrower than Apex 19 — more attractive to solid ball strikers. Above-average workability for the players-distance category — clean compact players iron shape + thin topline allows shape control, but more shape-amenable than full GI; less workable than Apex Pro/CB/MB siblings.

On center strikes, the Apex 21 feels fairly soft and has a quiet impact sound. Body forged from 1025 mild carbon steel and patented urethane microspheres that deliver exceptional sound and feel at impact. Urethane microspheres consist of over one million tiny air pockets, help absorb mis-hit vibrations without sacrificing feel or sound. The Apex 21 iron delivers the level of feedback that players expect from a forged club, feeling fairly soft. Top-tier feel — 1025 forged + urethane microspheres + premium muted forged sensation + clear strike feedback.

On center strikes, the Apex 21 feels fairly soft and has a quiet impact sound — when you move away from the center, the feel firms up substantially and contact gets much louder. The character of the impact sound varies from a 'snap' on center to a 'clap' when you mishit a shot. Forging process leads to a muted feel and sound at impact that is hard to replicate with a cast iron. Premium sound and feel you expect from a modern players-distance iron. Above-average sound — quiet 'snap' on center + 'clap' on mis-hit (informational acoustic variation) + premium forged tonal character.

The Apex 21 irons are stunning at address with excellent forgiveness, especially for their size. Clean, compact golf clubs that fit the look of a players' iron, with a thin topline that frames the ball and is pleasing at address. Topline is a little narrower than Apex 19. 4.8/5 (96% recommended) on Callaway store rating. Top-tier address — stunning premium aesthetic + clean compact players-iron shape + thin topline + narrower vs predecessor + 96% consumer satisfaction.
