It is generally not good to put the wrong caliber ammunition in a firearm.
If there is one thing you can count on, its that the big name high profile trainers have their priorities straight. Sure, they charge a lot for you to come to their carbine/shooting class. But its not tennis we are playing here, its life and death!! Keep your head in the fight. It is also a good idea to buy the proven products the instructor recommends because of the quality, not because they personally benefit in some way.
The Blackopstoys Costa trainer doll!!!! I do not have any idea if this was Mr. Costa’s idea even though it has his Costa Ludus branding…. but Loosereounds thinks the instructor worship has officially gone too far.
