Emil, it would do in a pinch but there are better and lighter higher caacity options. Cheers and stay safe!

Any firearm you are comfortable with and is reliable will do! Go to the range and get use to it

No, it would not. It would be very hard to control in a .45 caliber and that is what most carry for 1 shot take downs for concealed carry. Two, no capacity. Too long to reload. In a fight, most people panic and won't hit the target with just two rounds unless you are very close to that target. For protection, these guns are worthless. Now if you wanted to carry it as a backup piece in case your primary weapon failed or jammed, that would be acceptable, but not as your primary carry. I carry a 1911 .45 with a polymer Keltec 9mm and even with the 9mm as back up, it has one mag in gun, 2 mags in holster for a total of 22 rounds since the 9mm is not a powerful round compared to the .45 and it has a shorter barrel and less range. In closing, if you want one get one, but don't carry it for protection unless it's a backup or a backup to a backup. Not worth dying over cause you only have two rounds in the chamber.

Emil, the bond arms 2000 would be fine for concealed carry. I'm sure plenty of people carry one. The only issue is you only have two rounds, so I'd carry extra rounds and practice reloading quickly. Other than that it's a fine carry pistol. Hope this helps.
