The answer to the OP's question can only be answered with a question-how many calibers are there? Might have to add, how many different models are there in each caliber?
Had to go look, which is a good problem to have. Except when you find missing calibers that one has ammo for, but hasn't yet acquired the peashooter to go with it. Need to rectify a few of those. This is just a good start imo...
