Short answer: Not enough. Taurus 1911 (.45 ACP) and Kal Tec P11 (9mm), that's all I have now. Looking to get a Taurus Judge as my next gun. That should count as two more calibers.
I counted 21. No wonder i have so much ammo.
I never realized i had that many different calibers.
I recounted this morning 22. I guess i have too many guns.
