Known by the companies that produce them, Simunitions or UTMs, or by their colloquially gifted name “Blue Guns”, reality-based training firearms for Law Enforcement and Military training exercises have been in constant use for the past several decades. Their high prices and strict guidelines have unfortunately led them to sometimes be scarcely used among the end users that actually need them the most. But this doesn’t mean they don’t have any training value. In fact, these are some of the best trainers around when it comes to trying to replicate actually working with firearms in a defensive capacity.
