I purchased a 3" barrel Bond Arms Derringer "Rough & Rowdy 410/45LC as it was the only one that Bi-Mart had in stock at the time. I'd read about them and I liked the look and feel of the gun. Unfortunately trying to find ammo was quite the challenge. I was unable to find any 2.5 in 410 or 45LC to shoot in my 3" barrel gun. Believe me when I say...
