I pay a lot of attention to holster availability.I never considered that it would be this difficult to find a holster for a currently produced gun. I guess this gun isn't too popular. I will keep this experience in mind the next time I buy, and look more closely at what accessories are available.
I used a Desantis Superfly when I had a Pico. The Superfly is a little bulky but it will definitely stay in your pocket when drawing the gun
Understand your issue with the Pico and the Sticky holster. I'm thinking about cutting a notch out or a slit into the section that catches the sight. Little to lose and I like the holster otherwise.
Do you run into the same issue with the rear sights snagging on the holster? The Superfly looks like the same design as the Sticky holster, so I figured it would have the same issue.
