Hello there, I need a gun for myself for self defence and have been reading a lot about the subject and have come to this two guns and find it hard to decide between them both. Sig P229 .357 Sig Five-seveN USG 5.7x28mm or maybe an 10mm Which one would you choose and why? If you want to suggest another pistol it is Ok, just keep it to rounds of similar ballistic properties., so please -do not- suggest some magnums or .45s. Oh, and cost is unimportant to me. All comments very welcome, thanks.
