Curious, why swap a HK for a Glock? I could never do that myself!
I have been all about DA/SA for over a decade. Mostly Beretta 92 models. But with lower back issues, I can't carry anything that heavy anymore... But, I bought a Beretta APX a over a couple of years ago. I carried it a few times, and it kinda got me comfortable carrying a striker fired gun again.
Then I discovered the 5th Gen Glocks in 2020. I haven't been into Glocks for years and years, and I found I liked the 5th Gen Glocks much more than the APX. I ended up selling the APX. I started to carry the Gen 5 Glock 19 occasionally, and I found I really loved it. I decided I didn't want a quite so heavy.
I also previously had a VP9, but only as a range toy. Not as a carry gun. For some reason, I bonded with the Glock 19. Gun fits my hands perfectly.
The G19 replaced my HK. I still have the HK, though. I still love that gun.
