Went with the full stipple kit and used the 16LPI tip.
Entire pistol was done in less than a half hour (minus the prep work with a Dremel), and the texture is extremely aggressive. It will not slip loose while shooting and makes shooting in the Georgia humidity a breeze.
The OTD kit is very high quality, and dead simple to do. Plan to hit my CCW with the 20LPI next.
*EDIT: Pic should work now.
