Waht's the difference in the 24/7 and the 24/7 long slide. I know this seems a stupid question, thanks for your indulgence.

Barrel length.

Long Slide is a little over 5 inches in barrel length compared to a little over 4 inches for the standard 24/7 Pro.

All are 24/7s. The one in the bottom right corner is a long slide.
