Of course best to rent each and fire before buying. That said both are good. Pretty close as you can see here…
I have tried Sig and it is nice CC, but every gun is different in every hand. Find the gun and hold it even if you cannot fire it.
Also pick a target and do a quick raise at safe spot. Everything else like features matter, but not if gun does not feel good in your hand.
That been said, go with Sig. whoops, my bias is not concealed.
Good luck. In this day, if you find one, buy it. It won’t be there tomorrow.
