I know we all have our favorites, but do you have a firearm that you are 110% confident will not malfunction (barring a major mechanical or ammo failure)? Semi-auto's in particular. I have an AR that is my favorite to shoot but short strokes now and then. Even my high-end AK has had it's share of hiccups. Of all my firearms, the only one that has been stone cold reliable is my POF P308. Does anyone else have an 'Old Faithful'?
