I've had an LCP, G19 and G26. I used all of them, but kept looking for something better.
I eventually settled on the Keltec PF-9 the lightest and thinnest 9mm on the market. The fact that the mfg made a small belt clip specifically for it was a real plus because it removes the bulk and cost of a holster.
I've had it now for a couple of years and I carry it anytime I get out of my pajamas. Highly recommended.
