I chose it over the sig p365 for a few reasons.
1. The sights were easy to pick up for me. I am left eye dominate but right handed, so when shooting both eyes open, it is difficult for me to quickly align a standard 3 dot system. But the u-dot or whatever you call it with the U in the back and the green in the front was a lot easier on my eyes.
2. The mag release was much easier for my "burger king" hands to be able to reach and it seemed to shoot the mag out better than the 365.
3. The trigger. While the 365 has a lighter trigger i believe with a shorter reset and arguably smoother, i just liked the hellcat's trigger better. It had more of a solid wall before before the break, making stacking the trigger a lot easier. Also everything seemed more audible and crisply seperated, such as the trigger reset.
4. I prefered the feel of the hellcat over the 365 also. It was weighted and shaped differently. Though the hellcat is more boxy i think, which i usually dont like, it felt comfortable in my hands. This was the most minor difference that caused me to choose the hellcat as they both werent bad in the hand, just a little different.
I also compared many many other small pistols but the hellcat came out on top with the p365 in second for what i was looking for.
I did really like the feel of the p365xl version, but a little larger than what i wanted for a secondary while on duty.
Also i tried the p365sas. I saw a youtube video on that holigraphic sight thing that is on it about the sun washing it out if the sun is behind you. While it was easy to pick up and align the sight, sure enough, even with overhead fluorescent light, the sight with get washed out and difficult to see if i put the light directly to the rear of the sight. Even with the lighting at a distance of 20 feet away.
