The goal for the Parsons Xtreme Golf (PXG) 0311 iron was nothing short of the Holy Grail of design: make an iron that looks and feels like a muscleback and plays like a game-improvement club.
To tackle that challenge, the team at PXG used some technologies that you can see, and others that you cannot see, to make one of the most unique clubs in the market.
Forged from S25C carbon steel, the club features four easy-to-spot tungsten weight screws high in the toe and seven more low in the toe of each iron, along the trailing edge. The screws are not designed to come out, but do bring the club’s center of gravity more in line with the center of the hitting area.
The inner portion of the chassis is CNC-milled before the forged HT1770 stainless-steel face insert is attached. According to Brad Schweigert, chief product officer at PXG, the faceplate is about half the thickness of most iron faces. If the hollow chamber inside the 0311 irons were not filled with a soft, thermoplastic elastomer (TPE), the faces would cave in after only a few hits.
“The TPE allows the face to move, but it does not allow it to move past its point where it will break,” Schweigert said.
So though the PXG 0311 irons have a moderately thin topline and just a touch of offset, thanks to having the heads filled with the rubber-like material, the company claims that golfers get more ball speed and enhanced feel. And because the TPE weighs less than the steel that would have filled the heads in any other blade, more weight naturally shifts to the perimeter, which increases moment of inertia (MOI) and forgiveness.
PXG 0311 irons are available in 3-iron through pitching wedge. Stock-shaft options include KBS Tour and Nippon Modus 120 steel shafts, along with Fujikura Pro and AeroTech Steel Fiber graphite shafts. Cost per club is $300 (steel shaft) or $325 (graphite shaft).
