Congrats on your G43!
G43 is the smallest of the Glock family in 9mm, but it still offers the same level of durability and reliability bigger Glocks have. It may not be as popular as some other guns that have more capacity, but I still feel well-protected carrying 7+1 rounds of 124gr HST +P in my G43 with MagGuts and 8 more rounds in my spare 8-rounder mag.
In terms of capacity for size, the 43 has been left behind by newer designs from other manufacturers, but my 43 was pretty easy to shoot decently and was Glock-reliable and that's not nothing. I wouldn't lose my mind if I had to carry one again.
