I can't speak to all lubes, but the Riggs seems to hold up really well. The training pistols, depending on the week, get from several hundred to several thousand put on them during the week. They generally don't get cleaned until the end of the week.Not to derail this thread or start a lube battle but do you have any issues with the grease getting gummed up and really nasty with high round count shooting sessions? I switched over to Ballistol recently and love how it cleans and protects while only requiring very little to actually lubricate.
I just got around to cleaning my first 21.3 which was a blue label gun and I assume police issued based on its character. It has an amazing trigger with a nice break but I noticed the internals of the lower were covered in grease. I thought, WTF? Who/how does grease get onto the connector bar and rails?
