So I relented and picked up the 365XL and I have to say I like it a lot. (I’ve sworn off sigs a couple of times). I tried one at a range and the trigger was pretty bad, fortunately the one I purchased was much better, pulled at about 4.5lbs after about 300 rounds, still pretty mushy though. Shooting wise was much softer then my 43x and 48 (which I’ve since sold my 48 if that’s any indication of how much I like the XL). I was also very pleased at the easy purchase with the slightly larger grip from aiwb. Easier to stay on target while shooting at speed, I was able to consistently hit an 8 inch round plate shooting fast pairs at 10 yards. I’ll need to work with it more with it but confident with it so far as a accurate shooter. My 43x and 48 are a good a bit snappier.
I absolutely love the feel of the 48/43x grip but seems the XL is a pretty good blend of shootability and ergonomics. Really impressed with it, I just hope it’s reliable. Pretty awesome with the 15 round option. It’s interesting because the 365w/12 round option is identical in length, but sig did a nice job of reshaping the grip on the XL to give you a little better feel, at least for me. As I mentioned above, I seem to be able to get a very consistent purchase out of the holster while drawing the gun. Overall really pleased with it.
