I don't know when your 3rd gen gun was made, but I have one made in 1927 that has a slide stop that has to only be fired with standard velocity ammo . Hi vel ammo will batter the slide stop over time and damage it. you can tell if it is the standard ammo only version by checking the slide stop at the back of the grip frame where the web of your thumb wraps around it. if it has cross-hatching similar to checkering, use standard ammo only. the newer versions are not available., I've checked.
