Trigger out of the box seems less than desirable, not nearly as nice as I find my 627 PC. Anyway, about 300 rounds thru it since picking up on Sunday. Was dry firing it last night, after about 100 pulls, I noticed that the trigger sticks as I start the double action pull. Once past that initial hurdle, no issue. But it's "sticky." Gun is clean, trigger doesn't look like it dragging on frame. Any ideas on trouble shooting? Thanks in advance.
