I do not have a membership to Costco but I know someone who does. And when I overheard them say they were going one day I asked if they could pick me up some Kirkland Signature golf balls while they were there because Costco is typically the only place you can buy them unless they are trying to move excess inventory online.
You may know by now that the Kirkland Signature golf ball has a bit of a past. Titleist accused Kirkland of stealing a few patents from the ProV1 design and slapping their name on it. Much of this happened in 2017 and it appears a settlement was reached between the two companies.
But that is not what I’m concerned about. Its all about finding out what the best golf ball is. And thats what I did.

Rackham Golf Course. 9-5-19. 78 degrees. Light breeze. Sunny.
Driver – Not impressed. I was a good 10 – 20 yards back from my average landing spots on the golf course. No draws. Felt like I had to hit it perfect to get anything on it.
My drive on the 299 yard Par 4 17th hole is a great example of how much shorter the Kirkland Signature is than other golf balls off the tee. My tee shot is usually in line with the tree you see on the right in the photo below. I’m a good 25 yards short of where I hit the Bandit SB and Titleist AVX.

Fairway Woods – Impressed. What I was not able to get in distance with the driver I was able to make up with my 3 wood. Almost made it to the green side front bunker in two on the Par 5 515 yard 1st hole.
Sent a missile from 215 yards out on the 431 yard Par 4 18th hole which ended up 10 feet above the hole. The shot plays 235 yards as its uphill from 75 yards out. Had to hit 3 wood instead of 5 wood in every situation due to being 15 yards back from my normal landing spot with driver.
It was pretty sweet watching it go. I was about 15 yards off the right side of the fairway and watched it hook back from the left side of the fairway all the way across the green. It had some serious side spin.

Irons – Not impressed. Did not have that nice compression feeling you get with a Pro V1. The Kirkland felt a little clunky. Outside of the best 5 iron I’ve ever hit out a fairway bunker on the 9th hole from 160 yards which landed 10 feet from the hole there wasn’t that much to talk about. Out of my 4 Greens In Regulation, the 5 iron was the only one where I took a full swing with an iron.

Wedges – Chipping was pretty good. Did not have a lot of GIR with the irons which left me with a lot of chips. Only had one chip that checked up and the rest rolled out.
Distance was good and the Kirkland did what I wanted it to do. That is, except for getting out of the bunker on the 8th hole. Caught it clean and sent it over the green into another bunker.
Putting – Excellent – 7 one putts and 1 three putt. I was rolling everything in. The Kirkland didnt feel soft at impact but rolled with purpose.
Durability – Still in pretty good shape after one round and thats not bad seeing how I hit from the bunker a few times and even the cart path. Like I said above, the Kirkland and irons did not like hitting greens.

Barely a scuff mark on the Kirkland Signature. I could definitely get more rounds out of it.

Score – 87. GIR – 4. Putts – 30. Fairways – 3

As my round continued I just kept thinking that the Kirkland Signature was not living up to the hype. They were not bad but not great either. The Titleist NXT Tour comes to mind as something comparable.
While I was putting this review together I found out that Kirkland moved manufacturers from a place in South Korea to China. Looks like a lot changed during that process and the latest design is a lot different from the original. More than likely the new Kirkland Signature golf balls have lost their performance.
I also found out that Kirkland makes two golf balls. A Three-Piece and a Four-Piece. I thought all along they made just one. I played the Three-Piece and its the Four-Piece that is said to be similar to the ProV1. I’ve been duped!

Still, at $1 per ball you are probably not going to find a better deal on a decent Three-Piece golf ball. I have two dozen of them now due to Costco only selling them that way and its probably the only time I’ll ever buy this golf ball.
Even at that price I’m still sticking with the ProV1. Its just that much better than the Kirkland Signature 3-Piece. Hopefully I’ll be able to get my hands on the Four-Piece and give it a try.
