Ammo companies seem to think the only rounds handguns come in are 9mm, 380 Auto, 40 SW, 22 LR and 45ACP. I can't remember the last time I saw a box of 30 SP, 357 Mag, 44 Mag, 45 LC etc... on the shelf
It has become the "Big Box" mentality anymore in this new world.
Buy what we want you to buy and like it.
