No, this isn't a question for the basement thread 'cause I already know that answer.
Do you like a flat trigger? It wasn't even on the radar until I got a Sig P320 X model and a 365 XL, both of which have flat triggers. The first range session with the 320 left me with a blood blister on the bottom edge of my index finger since that would get caught between the trigger bottom and the guard. The 365 XL didn't do that but shooting it and the standard 365 side by side I see no benefit or detriment. Changed out the trigger on the 320 for a factory curved one and it feels so much better, it seems like I can control the trigger better. Going to order a factory curved trigger for the 365XL later today.
The race guys like the flat triggers for some reason but they're a complete "meh" to me. Doesn't mean others might not derive a benefit from one so anybody here really, really liking them?
