The Pronghorn tip provides two tips in one, speeding up the stippling process while providing a random texture. Simply do your straight lines with the tip horizantal or vertical, then come over everything with the tip in any direction you want! Provides a moderate to aggressive texture.
7-8 on the OTD Grip Index
If you have Pmags, or guns such as the Ruger semi-auto pistol lineup (LC9,LCP), Smith and Wesson Bodyguard, you will find this tip to be most useful. The glass content in the named items (not a full list obviously), is such that they do not stipple quite like a Glock, XD, M&P. They will stipple with a waffle tip but in general the Pronghorn tip will give a more aggressive grip.
