to follow up, gen 5 is actually a significant upgrade beneath the surface. it's not just finger grooves, front serrations and ambi slide lock.
>much more mechanically accurate barrel
>built in magwell which is actually best in-class
>redesigned firing pin block geometry that gives a better trigger feel, unless you get one with down syndrome like my 19x and has a huge notch in the takeup
>standardized on g19 locking block for later gen 5 releases meaning much broader parts compatibility across different sized models
and then it brings over all the gen 4 improvements like the dual recoil spring, adjustable backstraps and side grip texture that still sucks but sucks less than gen 3
Faggots certainly are quick to say that Glock doesn't provide anything unique but I don't see PDPs and M2.0's having flaired magwells, overinsertion tabs, polygonal rifling, dual recoil springs, etc. That's not to say that those two guns aren't great in their own right, they also do things Glock does not.
