A revolver can’t be loaded nearly as fast as a magazine fed semi auto, practiced shooter or not.
Miculek used moon clips for his record. Most revolvers aren’t cut for moon clips, and most shooters will never be as fast as Jerry Miculek, even if they use moon clips. If you have ever used moon clips you know they are temperamental, and they don’t get better if you carry them around for a few days.
That being said, I think that there are some good reasons people to decide to carry revolvers. I think personal preference can greatly aid proficiency along with copious amount of practice.
You can shoot 45 Autorims in the 625....also in the Model 22 (which is the SW replica of the 1945 45DA). The Governor is cut for moon clips but they say not to use autorims in them.... Have all three...
