Although there is no substitute for live fire training, the cost of ammo, range time, weapons maintenance, etc., may not always fit our situation . There is a great product that can still give you the pleasure of a good day on the range and further sharpen your skills. The SIRT (Shot Indicating Resetting Trigger Laser Training Pistol and the exclusive laser feedback mechanism).
“The SIRT training pistol is built  to look and feels like the real thing by matching the size, weight, and center of gravity of the live fire pistol. In addition, the SIRT Laser Training Pistol even offers a host of  features including weighted training magazine and replaceable sights.”
I would recommend any shooter to look into a SIRT training pistol. You can never train enough!
