The comp keeps the muzzle nearly level. It takes very little movement to place the sights back to point of aim for a rapid followup shot. Recoil is minimal with 165 or 180 gr rounds. I accustomed to keeping a .454 Casull under firm control, so the Glock 23C is much easier.
I don't carry it for self defense. Strictly for playtime at the range. An S&W 686+ with .357 mag JHP is the preferred carry. It doesn't fling brass all over the place either :-)
