 the body has an injection port extending into the internal cavity, the elastomer material is inserted through the injection port, and the injection port is closed with an external plug; 
 the elastomer material extends to an elastomer elevation that is greater than a maximum elevation of the internal weight; 
 at least a portion of the second part of the sole portion is welded along the first part of the sole portion; 
 in an address position, the second part of the sole portion has a strike plate rearwardmost edge, and the elastomer material extends rearward of the strike plate rearwardmost edge; 
 a portion of the strike plate extends further toeward than the second part of the sole portion; and 
 the iron-type golf club head has a club head volume of 40-80 cc.
