Here is a useful taining device from Mantis that actually makes it a fun as well as useful experience. It is called the Mantis Laser Academy. It works with most semi-auto choices and should easily get you that trigger control/dry fire practice that we all need to do more often!
You can do all of this with absolutely NO alterations to your equipment.
