FWIW, many people try to rack slide w/ muzzle pointing away from torso, pistol gripped by strong hand, slide pinched between thumb and fingers of weak hand, palm of weak hand down. The two thumbs will be on opposite sides of pistol. VERY hard to do.
Instead, grip pistol in strong hand, pointed ACROSS body. Grip slide with weak hand, using all fingers and heel of hand- and SHOVE hands towards each other briskly. If do this on a range, be sure to rotate body (to the right if right handed) so that muzzle is downrange. Both thumbs will be on same side of pistol- between pistol and body. MUCH easier to do.
In all fairness, will say I am still a fan of a good DA revolver, but most folks CAN shoot an auto using above.
