I'll second the Seecamp idea.
Smaller/lighter than the Guardian.
More likely to be reliable out of the box than KelTec.
If you've got a FFL who will do a transfer for $20 or so, you could get one for ~$400.
I got mine from Ron Gilstrap in Texas.
+$35 for extra mag.
+$30 for transfer/background check.
$435 out the door.
The Keltec is less ammo sensitive, and lighter.
If you can get a KelTec, and get the bugs out of it, they are good guns.
The Seecamp just feels like a work of art.
It shoots like one too.
Mine is flawless with Silvertips and GoldDots.
If I get a good batch of Fiocchi jhp, they are 100% also.
Now, even the Win. White Box at Walmart will shoot with only a couple of jams per hundred.
