I have several P365s.. one an XL with Wilson grip and the others plain P365s. One is a dedicated practice gun.
Now I am a Glock man (and 1911 man and S&W K frame man) but... these P365s are the slickest CCW guns I have ever came across (and I say that being a gun nut at age 16.. and I'm 68 now!)
I have zero accuracy problems with the Sig P-365 in any flavor but... I don't swap slides.
And my favorite practice load is using a 95gr (.380) fmj with same power charge I use for 125s using Unique power. The guns kick much less and it allows me to hip shoot one handed with ease for lots of practice (you see I have thousands of those 95 grain pills!!)
I am definitely sold on the P365 platform.
Back in the day of single spring recoil springs my Gen3 G26 was more accurate than my Gen3 G17. We attributed it to the tighter lock up from the spring during the trigger pull. Which I got affirmation of from a engineer inside a certain company. I don't think that's an issue these days.
And in his previous video review of the spectre comp, the group was equally tight.
