"...I don't get why one factory one has 7 and one 8..."
For shooter preference. Original 8 round 1911 mags (and still many offered 8 rounders) were/are 7 round mags with essentially a shortened follower and spring with less coils. Those mods were required to get tge extra round in the msg.
You'll eventually notice the 8 round mag springs will fatigue fairly quick and the top round nose dives when chambering the first round. Last round inertial feed will also show up play as well. New higher force springs typically fix that as long as the feedlips are in good condition. I typically load this type of mag down one or use 7 round followers and springs.
New generation 8 round 1911 mags utilize a slightly longer mag body to house a more stable foller and extra coil on the mag spring.
