I bought a new holster I like
If you plan to carry on your belt, I've found a very nice holster.
It's called the Blackhawk Serpa Concealment series.
They come with several configeration adjustments:
1. Belt loop mount
2. Paddle mount
3. 3 different slant adjustments - FBI / straight up & down / cross draw.
Very light to carry and they have a trigger lock system so that the gun will not come out accidently.
I bought one to carry my S&W Sigma in it.
It is injection molded carbon fiber and not kydex.
I called Blackhawk's 1/800 number and they told me the item number and said it was listed under "S&W m&p 9/40"
• SERPA Lvl 2 CF Holster - BK - S&W M&P 9 / 40
• 410525BK-R $39.00 from Tactical solutions. This is the right handed model number - L (instead of R) for left handed model.
Here's the cheapest website I found that carried left handed (for me) .. you might find it for less elsewhere.
After carry it for about a onth i bought one for My Kimber & My Springfield XDMm too.
I hope this helps - it's a great carry rig.
