Sigma 2

The Sigma 2 is Ping's follow-on mallet-and-blade line, built around the same idea as its predecessor: a dual-durometer face and a choice of head shapes to fit different strokes. Editorial coverage describes the face as a 2-piece Dual-Durometer PEBAX synthetic construction, with a softer front layer for shorter putts and a firmer back layer for longer ones, according to golfmonthly.com. Ping's TR, or True Roll, face pattern is reported by nationalclubgolfer.com and golfmonthly.com as varying in depth and pitch across the face to speed up off-centre impacts and keep ball speeds consistent, and australiangolfdigest.com.au describes the same idea as grooves changing pitch and depth to control ball speed depending on model.

The line's calling card, by most accounts, is choice. golfalot.com lists head shapes running from the Anser, Arna, Kushin C, Tyne, Tyne 4, and Wolverine H through to three new shapes, the ZB 2, Fetch, and Valor, while golfmonthly.com counts ten shapes in total and tgw.com says nine. Grip options are reported as the PP60, PP61, and PP62, with golfalot.com testing the PP60 midsize grip and noting the pistol-shaped PP61 and larger, rounder PP62 as alternatives. Finish comes in Platinum or a black "Stealth" option, per golfalot.com and pluggedingolf.com. Length adjustability is another point of near-unanimous editorial attention: golfalot.com describes a key that fits into the top of the grip so the grip slides up and down the shaft, with a range most sources put at 32 to 36 inches, save for golfalot.com's own figure of 32 to 26 inches, which reads as a likely transposition against the rest of the field. Ping's own page, captured by ca.ping.com in 2019, speaks to the grip lineup directly, describing a midsize, lightweight design with a foam under-listing and dominant flats for face awareness, and a heavier option paired with the CB60 grip to deliver an assured feel and promote a smooth tempo throughout your stroke.

Reviewer sentiment across the line runs favorable. golfalot.com called the face-balanced mallet their favorite of the models tested and pointed to the long alignment line on the back as a genuine aid to setup. pluggedingolf.com wrote that the Sigma 2 putters are everything that you would expect from PING, loads of fitting options, great performance, plus something no one else has, while nationalclubgolfer.com found the feel off the face on the three models they tested absolutely fantastic. Community opinion on the Record echoes that, praising the feel and fitting range, though it also notes the insert initially felt a little too soft to some and that the putter wants to fall back on its haunches at address, a rare point of friction in an otherwise well-liked release.
