Over time I’ve gotten bored with handgun shooting in general. In particular, revolvers. I’m in the process of selling them off. I prefer sitting at a bench with a nice rifle & optic. If I had to name a specific handgun I got bored with, it would have to be Glock. I very much appreciate and enjoy the 1911, BHP and pretty much anything Beretta makes.
To be fair, all my handgun shooting is done standing in a stall at the indoor range. If I had enough property to set up a cool shooting field I wouldn’t get so bored.
