another not on the list is the Seecamp both 32 and 380 models. Very small precision made and fitted slide to frame. Have carried one for years as a back up to my 10mm primary.

Have a 32 Seecamp that I too carry as a deep concealment rig since the 80’s. Very durable , well made and easy to hide in the palm of your hand.
As you state .... precision.
I love my Seecamp 32. I never leave home without it - never. I have carried it for years.
If I had it to do over again, I might have purchased the 380, but that little guy actually hurts to shoot and of course, it’s double the already expensive price of the 32. ;>)
I may someday buy the 380 and give my 32 to my wife.
Nice and light
