Costco Kirkland Signature Irons

It’s the review you’ve all been waiting for. The most anticipated golf club of the 21st century is finally here! Somehow, we managed to get out our hands on them before the first batch sold out. Or I just got the heads up from our buddy Frank and ordered them in time. I’m talking about Costco Golf’s Kirkland Signature irons of course! These multi-material, hollow-body irons are designed to be easy to launch in the air with some solid distance at a wallet-friendly price point. I’m comfortable telling you, the Kirkland Signature irons deserve some legitimate credit.

The Looks

I’m not totally sure what my expectations were, but the Kirkland Signature irons exceeded them at first glance. Sure the top lines are a little thick and they’re a little long from heel to toe, but it’s well within range of an iron that I’d say falls on the border of game improvement (GI) and “player’s distance”. The profile is really clean with moderate to minimal offset that sets up nicely at address.

Aesthetically, I would almost say the polished chrome finish is a touch overwhelming on these irons. Many similar clubs of this “style” have a primarily brushed finish that will hold up better to divots and sand. While this is a small thing, I’m certainly curious to see how this finish lasts over time. (I’m not sure I’ll use them enough to find out, but I feel it’s a fair point to note.) Though the top line and face have a matted finish, the toe, heel, and hosel are a highly-polished chrome. Sun glare shouldn’t be too much of an issue, but should be a factor to consider. I wouldn’t mind seeing these sections dulled a little bit.

How Does it Feel?

As stated, the Kirkland Signature irons fall somewhere between a player’s distance and GI iron. When it comes to feel, the story is very similar. I’ve managed to hit many hollow-body irons across the spectrum from “super GI” to “player’s” and they all have an almost signature feel. Hollow GI irons tend to have a little less feedback and are more springy, whereas a hollow-body player’s iron will be firmer in order to provide more face response. The Kirkland Signature irons fell somewhere in between there. There’s a definite springiness to the face reminiscent of a GI iron, but the precise feedback is closer to a player’s iron. A total “Goldilocks” situation, if you will.

You also have to consider the True Temper Elevate 115 shafts in the Costco irons. These are mid-weight, softer steel shafts that are easier to launch and spin a little more. As such, this shaft adds a little more life to the club. I would go so far as to say that players with more aggressive transitions and faster swing speeds could run into an issue with this shaft. That’s fine, of course, these aren’t built for that player.

Additionally, the soles are crisp through the turf as they aren’t super thick, but still have enough body to not dig deep. I thought there was a pretty nice little snap off the face at contact as long as you didn’t come down too steep and dig a trench.

How Does it Sound?

Hollow-body irons all have a slappy sound to them that varies depending on the club size and materials used. But rest assured…they all have this general characteristic. The Kirkland Signature irons are filled with a urethane insert that helps dampen the sound. Without this, the sound would be more metallic as opposed to the sound these irons actually have. As mentioned a few times already, these irons fall between GI and player’s distance so they are a little more compact, which plays a role in the sound as well. With all of that said, I would classify the KSig irons’ tone as a pretty tight “snap” with a slight hint of “whack”. I’m not telling you that you’ll mistake them for a forged iron, but they don’t sound bad at all.

On-Course Performance

When it comes to the Costco irons, I think we need to consider who they are made for. These irons are designed to fit a wide range of players seeking forgiveness, easy launch, and strong carry distance on a budget. Referring back to my point above about the shaft selection, the True Temper Elevate 115 is a versatile, easy playing option that will fit a pretty wide range of golfers. That said, players requiring stability and want less spin with a lower trajectory – probably not the greatest fit. As of now, the Kirkland Signature irons come in regular and stiff flex.

By design, the KSigs are meant to get up in the air quickly and carrying further. This is achieved by placing an internal tungsten weight low in the club head. Placing weight low in the head brings the center of gravity (CG) down and promotes a higher flight with more spin. Balancing out the low CG is a progressive “power loft”, meaning the lofts are stronger throughout the set, but the short irons are closer to more traditional loft specs. 20º is definitely strong for a 4 iron, but that’s pretty standard for a power lofted set. As such, I was hitting these clubs a long way. Flighting the ball down was a bit of a challenge, but I’m sure a better player would be just fine. I didn’t notice any directional bias outside of the shaft not being a great fit for me.

Final Thoughts – Costco Kirkland Signature Irons

Credit where credit’s due, the Kirkland Signature irons are pretty solid. I’d even say that these have been the most impressive Costco Golf item yet. These irons are created to be a playable club that will work for a wide range of players and I think Costco accomplished this. I’m not saying they’ll be confused for something buttery like a Miura anytime soon. Or better yet, a custom-fit club tailored precisely to your game, however, the KSig definitely delivers a mass appeal package. And man, that price point is pretty tough to beat if you’re looking for a “good enough one size fits all” option. I also think the Costco Golf devotees are really going to be very pleased with the KSig irons. Those loyal fans have truly been rewarded for their commitment.
