I found the LCP would sting the web of my thumb
AND it was only a .380.
I thought the DB might as well, but haven't found that to be the case.
My only modification has been sanding the inside , bottom of the trigger guard. Below the trigger. Mine was rough and irritate my index.
But so did my G 20. Some 240 and then 600 grit smoothed that right up.
I wish the DB would remain open on empty. My only complaint after 5 boxes of reloads.
