I've spent the last four months carrying a 642-2 as my "always" gun, which, due to being in a professional environment, means I invariably end up with a J-frame on me far more often than my Commander or my Glock 19. For context, I have carried medium-framed semi-autos consistently, for or outside of work, for ten years.
This question does not apply to pocket carry, since I normally walk around with my hands in my pockets. Establishing a grip in that context is a non-issue.
However, when I compete with my J-frame or opt to carry in a kydex AIWB rig, I am consistently running into an issue that I have had zero luck remediation through dry-fire.
With pistols, I index my primary grip by beavertail/hand web contact and maintaining a high thumb position. I bury my hand as high as it can go before closing my grip. A lot of this comes from using an ALS holster at work when I was younger.
With a revolver, I don't have that contact point, so it's really screwing with my ability to establish a master grip, even with slow, deliberate dry-fire draws. There's no beavertail. At speed, I sporadically jam the web of my hand over the hump on the rear of the frame where a beavertail would be.
Has anyone else experienced this issue? If so, how did you overcome it?
