I have a 357 magnum which I just bought for home defense. I welcome a discussion of whether I should use 38 or 357 ammo for HD. I had originally ordered a Ruger KGP 141, but the dealer could not find one available, and after waiting for it for three weeks, I started wondering if I should rather get a 38 instead of a 357 (Mas Ayoob had suggested that in one of his books which I read). When I went in to see the dealer, I asked for a 38, but he recommended that I stick with my original plan to buy a 357. He suggested the Taurus M627 357 magnum 7 shot with ported 4" barrel, which I bought. I had already bought 357 ammo while I was waiting for the gun, so I forgot the 38 vs. 357 question until Patrick Graham brought it up on another thread. Bear in mind that I already have the 357, so the question is not whether or not to use a 38 revolver, but whether to use 38 or 357 ammo in the Taurus M627 for HD.
