Most shooters eventually consider some manner of equipment upgrade to improve accuracy or speed.  Popular options include grips, trigger jobs, sights, and of course, a new handgun.  There are some factory grips that can get slick with shooter perspiration, and some service-type handguns have rough triggers. Smaller weapons may not  have good, clear sights. However, generally speaking, most modern handguns are okay.  Take the cash equivalent of the upgrade that you’re planning and treat yourself to some practice ammo.  Training trumps equipment nine times out of ten.
