How large can it be??
I have a Ruger P95.
It's not the smallest gun in the universe, but it can be concealed.
It is also built like a tank and digests everything you would care to feed it, including wolves!!
There are now several holster makers that make products for it.
I just checked Safariland and their model 2 for the P95.
It is level 2 retention. I'm not sure what your agency requires regarding that, however!!
