Question for the AAC reps. What all calibers are safe to shoot through a Tirant 45?

I know .45, .40 and 9mm, but what about something like .38spl/.357mag or .44spl/.44 mag? 10mm? Will any pistol round that's .45cal or less work?

Tricky question to answer as many variables are involved i.e. barrel length, ammo type ect.

Bottom line the answer is 45acp and 9mm as that is what it's rated for and tested. Many users shoot low pressure calibers with no issues such as 38spl and even subsonic 300 AAC Blackout.
