People often train themselves to release the slide by pulling back with their weak hand in an atempt to overcome confusion of using lots of different guns. I am also a lefty. I own a bunch of guns. Some even have a slide release on the right side of the gun. But I use my weak hand to pull back the slide on everyone of them.
Romans 1:16 I am not ashamed of the gospel, because it is the power of God for the salvation of everyone who believes: first for the Jew, then for the Gentile.
