Where to find a Trigger Stop Screw ?

hi, 

I'm looking for a Trigger Stop Screw.  The type that has a rubber button on one end and is tapped through the trigger.  It is used during DA shooting  to stage the shot just before the hammer drops.

My Trigger is already tapped for 6-40.   

I checked brownells the only have them in 8-32 tpi.

Please suggest where I might be able to find one.  

Thank you.

Try the fastener isle at your local hardware store. There might be a tray labeled "gun screws" which will have 6-40.

search "6-40 soft tip set screw"

Or get a regular set screw and glue a slip of rubber to the inside rear of the trigger guard.
