So, I have one more permit to use and I am debating between the Bersa Thunder 380 or the Kimber Micro 9?

What do you guys think?

Apples vs Oranges, but both are reliable.

I've got a Micro 9 and love it. Accurate, reliable, and well-made. 

How does the micro 9's recoil compare to the recoil of a kel tec pf9?

Micro 9 sweet gun I shot one at shot show extremely controllable in small platform, accurate. it was fun to shoot. 

Just sold a Bersa Thunder. Great little gun, but the difference in ammo prices, even before this nonsense, was pretty wide.  Side to side firing comparison between the Bersa and my P365 was pretty close. Extended pinky base on both make a big difference. 
if you have the means, the Kimber is probably the way to go. 

I have also heard that 380  ammo can be more difficult to find recently.

.380 is available but expensive. I just bought a Ruger LCP II and  enough ammo to practice  1-2 times with a month and an extra box of 20 for home. Averaged $40/ per 50 FMJ range and $22 /20 for ARX.
