I think this is an important point especially when you think about the 43. For me the 43 is a j-frame replacement type of gun. If I start comparing it to G19 (or even a 26) - I start getting disappointed in what those larger guns offer vs. what the 43 offers. However, there are circumstances I need or want that 43/j-frame gun and I am willing to accept those trade offs. The problem starts when you get into guns that are between them like the Shield Plus, 365XL, G48, G43X - am I trying to get a smaller G19 or a slightly larger more capable 43? At that point - prioritization of what is most important to you is going to be very important. I think psychologically, we are always trying to get a smaller G19 and there are a lot of options there.
I always want an option in my safe of the "smallest gun I can carry anywhere at anytime". At this time, the G43 falls into that niche. Its not a compact gun replacement. Its a j-frame replacement.
