Well, to cause a disturbance in The Force, I will admit that have been doing a bit of dry thumb-cocking, with a GP100, recently. It is not because GIGN, or even because the first three letters of my French-ish* surname are “Gig.” It is because the joints in the fingers on my left hand are suddenly starting to show their age, while my left thumb remains healthy. The day may come, when my long-stroke DA trigger-pulling capability will be diminished. Thumb-cocking a DA revolver is relatively clumsy, compared to the same task with a classic, SAA-pattern single-action revolver, so, it seems necessary to preserve the skill to cock a GP100 hammer, while this old dog is still able to learn new tricks.
Notably, one reason I bought my well-preserved, (not “collector” grade) post-WW2 five-screw pre-Model 10 snub-gun, is because those old-pattern S&W hammers have more-cock-able spurs than the newer and current K-Frame revolvers, such as my pair of Model 64 snubbies. I was already foreseeing, a few years ago, the time when I might want a 2” K-Frame, with a more-cock-able hammer.
Of course, I will continue to train long-stroke DA, as the most-important revolver trigger skill, as long as it remains practicable.
*Arguably, Lorraine is not French, but its own cultural entity. Not so long ago, it was independent. My surname does not actually follow the normal rules of French pronunciation, so may well be transliterated.
