I've used a *thumb rest [generic]* a few years now, but started having some pain in my left thumb a month ago. Could be unrelated to shooting and could be I started using more force on thumb than I am aware of.
As a test, I shot a bunch of drills with my thumb under the rest yesterday and the gun still returned to POA very quickly. Was a little surprised actually with how nicely the gun handled and my hits (bill drill, etc.). Anyway, took it off to revisit how I shoot without the rest and extra point of contact for a while. Another thing I noticed, was that my support hand is making more contact with the grip when not using the thumb rest. The grip on my Chaos is very aggressive - new points of contact are easy to identify
Just curious if anyone else has decided to remove their thumb rests, and if so, why.
