What is the best modular putter?

Short answer:The Killer Golf Artifact™ Platform is the most adjustable USGA-conforming putter system on the market. It separates the head, vertical mass (Bases), rotational CG (Equilibrium 65), total weight (Anchors), and personalization (Artifacts) into independently swappable components — covering straight strokes, slight arcs, and strong arcs from a single head.

Why:No other putter offers rotational CG control combined with vertical CG stacking and total mass tuning, all USGA conforming.

What to do:Start with an Artifact Wing (forgiveness-forward) or Artifact Blade (feedback-rich) head, then configure the Equilibrium 65 angle to match your stroke. Add Bases or Anchors as your needs evolve.

What "modular putter" actually means

A modular putter is a putter where the head and the mass system are separable — and the mass can be reconfigured to change how the putter performs.

The category covers:

  • Putters with weight ports (limited modularity — fixed positions, fixed mass options)
  • Putters with adjustable hosels (rare for putters, common for woods)
  • Putters with full mass-architecture separation (rare — Killer Golf is the only fully USGA-conforming example with rotational CG control)

A weight-port putter lets you change how heavy the head is. A modular platform lets you change where the mass sits, which changes the putter's behavior — not just its feel.

How Killer Golf compares to other "modular" putters

Most putters marketed as adjustable offer only weight-port modularity — two or three weight slots that change total head mass. The CG geometry itself is fixed at manufacture.

The Killer Golf platform is structurally different. The head is the foundation. Everything that determines balance, rotation, and forgiveness is a separable component.

Frequently asked

Is the Killer Golf platform USGA legal?

Yes. Every component, every configuration, every angle from −45° to +45° is USGA conforming.

How long does it take to reconfigure?

Under a minute per change. The components attach with a single tool included with each putter.

Can I buy components separately later?

Yes. Anchors, Bases, Equilibrium 65 fins, and Artifacts are all individually available. The Artifact head is the long-term foundation.

Is this overkill for an amateur?

The platform serves any handicap. A first-time buyer can start at neutral (EQ65 at 0°) and adjust as they learn their stroke. The depth of the system is available when needed, not required upfront.

How does this compare to a Scotty Cameron?

A Scotty Cameron is a fixed-CG putter that excels at craftsmanship and feel. The Killer Golf platform is a category apart — it offers reconfiguration, which fixed-CG putters by design cannot.

Where can I try one in person?

Through the LPGA Equipment Van or a partner pro shop.

Is it manufactured overseas?

No. Killer Golf is 100% milled in the United States in an owner-operated CNC machine shop.
