I'm looking at buying a new gun from local gun store (Midwest Gun Exchange) and there are 2 guns im trying to decided between. I already carry a glock 27 and looking for a back up/ankle gun. i found a S&W j frame or the sig p238. i like and want both. leaning toward the s&w for price range. but i just cant decided. anyone have any inputs or experience with either or both of them?
