303 stainless

There’s lot of talk about the Kirkland golf balls being the same (or better) as the Pro V1 and the Kirkland Signature putter being comparable to the Scotty Cameron Newport. Costco works hard to offer products that are a great mix of performance and value. If you have ever tried the rotisserie chicken, you know what we mean. 

During our 2021 Most Wanted Putter Test, we analyzed the Kirkland Signature putter’s performance from five, 10 and 20 feet. The results were not as good as we had hoped. As you will see, the club has some good things going for it but when the majority of positive feedback deals with the grip of the club, there are some issues. 

Kirkland Signature Putter Product Details

The Kirkland Signature KS1 is a forged CNC blade-style putter with an adjustable heel and toe. The putter is sold for a price that is hard to believe, considering the technology that was incorporated into the club head. 

In addition to the CNC body and face, a SuperStroke CounterCore Mid Slim 2.0 grip helps improve stability and feel. Typically speaking, a putter with precision-milled 303 stainless insert does quite well in product testing because of the feel and consistency. 

An adjustable weight kit is sold separately if you want to fine-tune the feel. The classic blade-style look is very similar to the premium blade putters on the market but the head is slightly larger. 

 This putter comes in one length, 34.5 inches, and with a head weight of 340 grams. In our Kirkland Signature putter review, you will get some more insider info into how this club performs on the golf course.

How We Test 

The Kirkland Signature putter was tested as part of our 2021 Most Wanted Blade Putter study. We tested 23 blade putters at five, 10 and 20 feet. Particular attention was paid to choosing putters that allowed for more one-putts. The test results included 80 hours of research and more than 10,000 putts hit. stainless steel

Kirkland Signature Putter Review

The Kirkland Signature putter ranked 20th out of 23 putters. We had high hopes for the Kirkland Signature KS1 simply because it’s a 100-percent CNC-milled putter for less than half the price of other CNC-milled putters.

Performance From Five Feet 

The Kirkland Signature Putter ranked last out of 23 putters for its performance from five feet. Our testers found that their confidence and overall performance from this distance was the worst of all the putters they tried. For reference, the Odyssey White Hot OG stood was the best blade putter in the 2021 Most Wanted Blade test. 

Two of the things that stood out during testing was the way the face of the Kirkland Signature putter feels a bit closed in addition to the high loft of the putter head. The closed face can be forgiving for longer putts but, in the five-foot range, it can cause putts to go left and miss the cup. Higher loft also seemed to create some inconsistency in the roll for these shorter putts. 

Performance From 10 Feet 

From 10 feet, we saw the best results with the Kirkland Signature. The putter ranked eighth from this distance and we can’t help but wonder if this is where the grip technology came into play. Making consistent putts from 10 feet requires stability in the hands provided by the SuperStroke grip.

Performance From 20 Feet 

From 20 feet, the Kirkland Signature KS1 ranked 17th out of 23 blade putters. The problem here has to do with the testers’ contradictory comments about feel. Some said the feel was hot with high MOI while others said it felt a bit soft. 

They were all using the same ball. 

The explanation for this is just consistency. As great as the putter head can look and as many refer to this as looking like the Scotty Cameron Newport, the overall performance coming off the face is significantly different. 


The Kirkland Signature putter finished 20th, a fairly disappointing finish for a really great value putter that we had hoped would perform a bit better. The Strokes Gained were some of the lowest across the board and left golfers feeling less confident over their putts. 

However, the impressive SuperStroke grip and ability to adjust weighting in the clubhead certainly saved the Kirkland Signature from ending up at the very bottom of the list. 

Tester Feedback

Despite the disappointing finish for the Kirkland Signature putter, the overall tester feedback was not all that bad. At first look, testers loved the classic design and the clean look. 

  • The SuperStroke countercore grip was a big hit, increasing stability and consistency.
  • Several testers appreciated the classic blade style commented that the overall material and design made the putter look cheap. 
  • The feel was described as “too light” from several of the testers, leading to inconsistency in longer putts. 
  • The loft of this putter is 5.4 degrees, more than one degree higher than any other putter we tested.


MyGolfSpy Feedback 

Bottom Line 

There is no doubt there are some deals to be found at Costco but he Kirkland Signature putter may not be the best deal on their shelves. The overall look, CNC milling and adjustable weighting seem almost too good to be true for the price. Unfortunately the performance of this putter, especially from the five-foot range, just doesn’t measure up.

Who makes the Kirkland Signature putter?

Costco. The Costco brand has several golf products including wedges, gloves and balls. 

Is the Kirkland putter the same as Scotty Cameron?

The Kirkland putter has a very similar look to the Scotty Cameron putter but the testing showed this putter to be considerably less consistent and the feel was not the same. The Kirkland Signature costs about a third of a Scotty. 

Is the Kirkland putter adjustable? 

Each Kirkland Signature putter comes with adjustable head weights. However, the weight kit to change the head weights is offered as an additional component and must be purchased separately. The Kirkland Putter is entirely functional with the stock weights in place; additional weights are needed to change the settings.
