The G26 only has one thing going for it, that being it takes G17, G18 and G19 magazines
If you are in a free state the +2 base plates help with the grip and the ability to use a G17 Mag with a +2 extension as a backup mag is nice, but other than that? Same for the G19 mags. The factory 33 round mags fit in the gun, but are not reliable IMHO as they rock too much due to the unsupported length. Even at the range the G18 mags in the G26 are not very fun to use. Once you have to reload one and see the $20 dollar bills worth of ammo go pew pew pew you'll understand, and yes they SUCK to reload.
The 43X runs circles around the G26 all day long IMHO
If you are in a free state, swap out the mag release for an aftermarket metal one and use the Shield 15 round magazines which are very reliable from all accounts, and the 43X kills the G26
A whole bunch of G26's became safe queens when the 43X came out, and the Sig P356 line too.
It was a good gun in its day because it was the only small 9mm polymer pistol that was affordable and reliable, but it was still a effn brick with a horrid grip length.
Now the kicker to this is I am not a fan of the G48, dollars to donuts I'd rather have the Glock 19
YMMV
