The BDA is a fine firearm. I don't own one myself, but have fired several. I've never known of one to have problems due to any specific brand of ammo, but if the spring in the clip isn't strong enough you're going to have problems, regardless of what you're shooting... My personal preference to carry (we can carry concealed here in Oklahoma, with a permit) is my S&W 1076 (10mm) due to its stopping power, balance, and weight. It's just, for me personally, the best overall choice. However, there are times that a smaller & less bulkier pistol is called for, so I have a Colt Mustang .380 that I carry in a pancake holster at the small of my back...or in a jacket/back pocket. My ONLY problem with the BDA is that it's a bit larger than I prefer a .380 to be. As for ammo, I prefer Federal or Winchester. The BDA is a fine sidearm & has great balance and accuracy with relatively no kick compared to my 10mm or a .45cal. No, it doesn't have the same stopping (or, at close range, knock-back) power, but it's easier to keep on target for better-aimed shots; which works just as well...a .380 round between the eyes is just as good as a .40cal, 10mm, or .45 round, even of the hole's not as large. Actually, in some cases, a .380 is a better option because the shooter doesn't have to worry so much about the bullet going through its target and into something or someone behind the target, as larger & more powerful rounds can do. Anyway, the BDA is an excellent sidearm, and for a skilled shooter it is as deadly as the 9mms everyone seems to be going nuts over. If my proficiency level weren't where it is, I'd carry a BDA or Hi-Power (9mm) as my primary carry, because they are easier to keep online than more powerful calibers. I just prefer the weight & power of the S&W 1076. I have thought about a compact .45, though.
