this has happened to me before. I blamed it on my larger hands. Some of the Nokta/Makro machines have a button right in the middle of the pistol grip. Absolutely killed my hand. I just couldn't get my hand comfortable with that button. Total deal breaker for me cant use em. The equinox fatigued my hand until I got use to it. It is a bit different and maybe not at the perfect angle. I will say the Anfibio has to be the best feeling grip I have ever used. HANDS DOWN ha ha ha
