Many new shooters think a better trigger, a better set of sights, or a different gun is going to make them shoot better. Generally it won't, or at least it won't as much as you would hope. More time behind the trigger is what helps, both live and dry fire. It takes a long time to develop the skills and muscle memory needed to shoot well. If you are jerking or mashing the trigger, a better trigger system wont help until you learn trigger control. If you flinch. better sights won't help until you learn to get over the flinch. If your gun twists and shifts between shots, new grips won't help until you develop a firm, steady grip technique.
When i started shooting handguns regularly, a friend and I got out almost weekly until winter and we even got out every few weeks in the winter. At the end of the year we were definitely better. At least now all the shots were actually hitting the target somewhere, but we werent what anyone would consider, good. Fast forward a few years, with regular range trips numbering about 25-30 per year and now we can pick up any gun, either revolver or semi- auto and shoot 9 rings or better at 25 feet and we can ring steel at 25 yards regularly, even with a little pocket revolver.
Someone famous once said, " Shooting handguns accurately is simple, it just isnt easy", and that pretty well sums it up. Aligning the sights, and squeezing the trigger sure are simple things to do, but doing them both at the same time, isnt easy
