Doug is my name, but this review is not about me or my opinions it's about a very high quality very safe tool that I will count on if my life is ever in danger. The Texas Defender I have recently purchased fits my hand very well 410/45 colt will do the job with a 3 inch barrel don't be afraid of reaching out beyond your normal personal defense yardage. I've only ran this gun 5, 7 ,9 yards with 410 birdshot and all hits were on paper. Believe me when I tell you I'm not a professional shooter, but the 45 colt is hitting consistently from 30 yards. This is from a three inch barrel, so if anyone is worried about accuracy as I was, you can rest easy with a little practice aiming an over/under can be done. That being said, the craftsmanship of BOND ARMS derringers is just unmatched. This little, very concealable, powerful, and beautiful derringer feels like a hand tank! Yes, you only have two shots at your disposal, but if you do your research most up close defense situations are less than two shots. Besides, I don't think anyone wants to be hit by two defensive 410 shotgun blasts.
