he's "like me", in his high 70's......I just caught that the 43 was for home defense. For some reason I thought it was for carry. I reread your original post and saw you said he doesn't want to carry.
Interesting choice for a home defense gun. If I only wanted one for home defense, I definitely would have wanted something bigger. In fact, right now, I am searching for a full size home defense gun. I currently have a Hellcat Pro and Kimber Custom 45ACP. I am far more accurate with the Kimber but it's only 8+1. And there's no rail for a light, which I want to add.
