Heavy Putter Mid Weight K4-M

This is post number two for HOG Putter Week!

I’ve been looking forward to putting a Boccieri Golf Heavy Putter in my bag for quite some time.  The concept is great.  A heavy putter is harder to yank or push off line.  A heavy putter makes breaking the wrists or wrist flipping difficult.  A heavy putter makes it harder to have a sudden, jerk of a transition from back to forward in the stroke.  A heavy putter will want to stay on the intended target line and promote a smoother stroke.

So do these things really happen?

Mid Weight K4-M Construction

The K4-M is a standard “toe-droop” design blade putter with a thin top line.  I’d say the most comparable design is to that of a Ping Zing.

Having putted only standard weighted putters until my Mid Weight, I want to say that the Mid is heavy.  At 750gm, this thing is drastically heavier than a standard putter or any club in the bag for that matter.  There’s a 200 gram weight inserted into the butt of the shaft.  Having this much weight up where the grip is makes “wristy” strokes nearly impossible, which is good.

The face of the putter is CNC milled with grooves which get the ball rolling end over end, better than a face with no milling.  The milling in the putter’s face also aids in giving the putter a soft feel.

Looks & Feel

Speaking of feel, this putter feels great.  The pendulum like stroke one puts on a putter this heavy is very smooth.  The timing and transition from back to forward with all that weight in the club is very smooth.  I find that my stroke stays on line very well.


The Winn mid-size V17 grip is very soft.  My hands feel like they blend right in and become one with the shaft of the putter.  With the weight and the grip combined, my arms, shoulders, wrists and putter all feel like one piece.

Head Cover

The included head cover looks great and protects the putter well.  I’m not a fan of Velcro enclosures which wear and the look shabby after a while, so the magnetic enclosure on this unit scores points in my book.


If you don’t feel that your stroke is smooth or you have a hard time with excessive wrist action; if you have a hard time keeping your putts on line or you have poor timing, try a Heavy Putter (any model really).
