If you want to get better at running a double action trigger, Ernest Langdon is on the short list of the best instructors uniquely qualified to show you how. I (Chris) recently got to spend some time with Ernest at his local range in Arizona to film a few things, including this interview all about double action trigger technique.
A lot of shooters are intimidated by revolvers and pistols with double action triggers. These guns do require a little extra effort to learn, but can be quickly mastered once the shooter understands the ways that manipulating a double action trigger differs from single-action or striker-fired pistols.
Please excuse the wind noise and shaky camera... it was super windy at the range!
