I purchased My Texas Defender in .410/45 w/2 1/2″ barrel about a month ago from Williams Gun Sight in Davison, Michigan, as a Back-Up to My full size 9mm. I was very impressed with the quality of workmanship and materials used in manufacture. Have only shot .410 shells in it and dont anticipate needing any other ammo. I truly like it and am very happy that I purchased it. Very easy to conceal. Anyone wanna buy My .22 LR Auto? This Bond Arms Derringer is so much better in all respects.
