I bought the 37.5 trying to figure out if it’s going to come with a longer grip it said on Amazon it was an arm lock putter called the pga store and they said it should come with a bigger grip but I could tell they weren’t 100%. They said if It doesn’t you can install armlock grip.

I bought the cobra agera 37.5 off of Amazon it listed it as an armlock putter I’m 5’6 will this size work for me? And does anyone know if it’ll come with an arm lock grip
