I have been through so many IWB holsters that its unbelievable.
I've come to the realization that the stealthgear ONYX model holster is the best option for me.
The difference is just night and day. I've carried full size pistols such as the G34 and various 1911's all day using the ONYX.
Stealthgear already makes a holster for the P-07.
For those of you unfamiliar with stealthgear's ONYX model of holsters it can be seen here:
http://stealthgearusa.com/pages/about-the-onyx-iwb-holster I am in no way affiliated with this company, this is a plea for help.
I'd love to have the ONYX model for my P-09 unfortunately they don't offer holsters for the P-09 yet.
They have a "contact us" page that only takes a second to fill out where you can make inquiries about models of pistols not yet offered.
Given enough interest I'd imagine that model would be pushed to the forefront of new production holsters.
If you have an interest in this holster, please drop them a line and let them know.
Here is the contact link:
