Rogers Shooting School Tap Rack Training Aid (TRT)

These are awesome for laser dryfire, if you have a 9mm pistol you can use these to train with your laser without having to rack after each shot

Useful to a degree. Unable to load the mag with snap caps to get the weight right. Company says some mags will and some mags won't. After using these a while, I opted to buy the model match SIRT mags that are fully weighted and also prevent slide lock.
