Kushin 4

The Kushin 4 arrived as part of PING's 2021 putter series, described by pluggedingolf.com as a mid mallet built in stainless steel and aluminum with tungsten inserts. The site reports a two layer dual-durometer insert, with a strip of red at the bottom edge of the insert and a matching red accent on the soles. The head wears a black finish with a strong white alignment line, and pluggedingolf.com lists an MSRP of $249 USD and a PP58 Midsize grip.

pluggedingolf.com's testing came away impressed with the putter's consistency, writing that "It only took three putts to be impressed with the consistency, with the balls finishing within inches of each other." Community sentiment on record echoes that read, with praise for the comfortable grip and flow and for the confidence it gave in aiming and alignment, though this should be read as opinion rather than a settled verdict.

PING's own product page, describing later Kushin 4 production, calls it a "Straight-taper, midsized pistol with larger flat surfaces for increased face awareness," built around a 17 inch grip that's "heavier than a standard grip to act as a counterweight for more stability and control throughout the stroke." That same page notes "Designated markings help golfers establish a consistent, confident setup over every putt," language that lines up with the alignment feedback reviewers gave the 2021 release specifically.
