The Callaway Apex 2021 iron is one of the longest and straightest clubs on the market. In addition to distance, you can expect to get a forgiving iron that launches high and has a great feel. However, if you consider yourself an artist and like working the ball in a variety of shapes and directions, beware that the workability is... Read more
Ideal for
  • Exceptional distance.
  • Predictable results on off-center hits allowing for maximum forgiveness.
  • High launching creating maximum stopping power on the green.
Not ideal for
  • The ball flight will remain consistent. With that in mind, it is difficult to work the ball left to right on command.

I tested these out multiple times when I was purchasing players distance irons in 2021. For players distance iron, the Apex 21s have solid forgiveness for a players distance and excellent feel. The Apex 21s made it to the final pairing during my purchase process but I went with another set. Due to the fact the other iron was leaning... Read more

Excellent, feel and forgiveness

Originally posted at on Dec 18, 2023
These irons have given me confidence. They are easy to hit and are very forgiving. After hitting my irons, my friend bought a set.

I’m a 5.1 handicap. I played the Apex for 3 years. Added the 3 iron to my set last winter and loved the graphite shaft in it. It was so light and the perfect club to use off the tee on shorter holes where placement and accuracy was required. Decided to buy the entire set, new, 4-AW with these same shafts. Got them last month. It’s cold here, too soon to tell the difference but shot a 78 then 77 the next day before the cold set in. I expect some extra distance using them.

Patient & knowledgeable
5 /5
I’ve been looking for a new set of clubs for a while but never seem to pull the trigger. Scott’s patience has been amazing, he really does know the game & the right equipment to suit any golfers needs & budget. I then decided I’d opt for maybe just a new driver since that’s the key to my game, getting accurate shots off the tee with some forgiveness & added distance

a pleasant surprise
5 /5
firstly, I figured it would be computer generated help so when I found out Gary was a real human being, I was glad. secondly, he was efficient in locating the clubs I was looking for. They matched up with my own research. So, he wasn't pushing one brand or another. thirdly he was knowledgeable in answering my questions. He also seemed to be genuine, and friendly. I am going to bookmark this site and when I go for my new wedges it will be one stop shopping.

Randy did a great job listening to my issues and concerns and coming up with options to benefit me. He gave me several options in each club that were different brands and different price points. Never did I feel pressured or pushed in any direction as far as brands went. Thank you for the insight and help and I can’t wait to try out the new set!
