Anyone in Northern California have a Glockworx grip job? (Silicon Carbide or Stipple) I'm thinking about sending a G20SF frame to Glockworx, for a finger groove removal & very slight reduction. This is for a USPSA Limited gun. I can't decide on the Silicon Carbide or stipple, so I'd really like to feel both before I have it done. I'd prefer a G21SF or G20SF, but any Glock will do. I can meet anywhere from the Modesto, East Bay, Stockton or East Bay areas (California). If you have either grip texture, but are too far away, any info regarding the grip job will help out too. .
