Guys, I'm debating my draw stroke regarding thumb position. I've been getting my thumb between the body and gun without any real problem and then flagging my thumb after the draw when mating with the support hand. I know many like to keep the thumb flagged during the draw by placing the thumb over the slide backplate or a little inside of that position.
With the large beavertail on a Glock 17, keeping my thumb flagged during the draw puts my thumb sitting on the beavertail and makes it hard to get the webbing of my hand high and tight under the tang. After clearing the holster, I start moving my thumb to the right to spoon with my other thumb - hoping the webbing of my strong hand snaps into place under the tang. I believe it would work better without the beavertail but I'm used to it being there.
Also, when drawing a smaller gun like the Glock 26, keeping my thumb flagged on the beavertail really doesn't feel secure because there's not a lot of grip to get a hold of.
So, is the concensus to work on the draw with flagged thumb or drive the thumb between the body and gun and get a full grip before drawing? Thanks for the input.
