Lotta choices out there for the M-9. With any holster it takes time and safe practice. IMO don't worry about speed so much as being deliberate. Speed will come. If you want outright greased lightning speed then look for a custom made competition holster.
There are a couple ways and methods for competition holsters, some are just skeletons. Then there are the metal holsters that are formed to the gun, I don't think anybody is using those much anymore except fast draw competition. Or you can use a leather holster that has been wet formed, dried, and then hot waxed. But a safety strap would need to be used with these as they are lightning due to the wax, unless they are formed tight enough into the trigger guard.
Almost any tack shop or leather smith can make you a speed holster. If you can find one the French police holster for the M-9 is fast. But it is a low ride holster on a swivel. They were selling for around 20 bucks surplus. Safariland made a high ride for the M-9 also that was fast, it was a leather hybrid. Safariland are expensive though.
