The Shadow is particularly well designed for the pinch method thanks to the nicely chamfered hole in the hammer.
I've practiced a lot holding the gun sideways to allow me a strong and straight on grasp of the hammer. Only when it is pulled back away from the sear do I put my finger on the trigger and lower the hammer fully. Using this method I have very good control courtesy of a strong pinch from either side that squishes pleanty of my finger tip padding down firmly into that cross hole.
I like the alchohal swab a few times during the day though. I'm going to borrow that one. Thanks.
I tried a bunch of the other method and at least with the Shadow I just did not find that it provided full control all the way down onto the nose of the firing pin. The Shadow has too much of a recess that the hammer sits down into to allow me to slide my thumb or finger out of the way and avoid at least a bit of a last "click" where the hammer is not in control. Other guns are different and on those I've found that the thumb under the hammer works nicely in those cases.
Anyhow, as much as anything I think it's a matter of what method you get used to using. I've practiced the pull back, finger onto the trigger and lower so often now that it's second nature to me. And maybe that is the key, lots of practice.
