Read an article about stippling Glock grips, which are part of their frame, with a soldering iron pin tip. Looked good and I am sure it would improve the earlier Glock's grip. The 4th generation Glocks have a better grip but you guys don't care. Have any of you tried stippling a Smith 3rd generation grip? I have some old LE grips that I may try the process after I get a soldering iron.
