I have a new pistol which has the Crimson Trace Laserguard and have been unable to find a holster that it will fit. I have two to return.
Any recomendations?

I've not bought from these guys, but they do offer what you are looking for.

White Hat Holsters

I have a IWB hybrid holster from White Hat. It seems like a good holster. but it doesn't conceal well for me in the 4 o'clock position.

I'm thinking about getting one from PJ Holster. They list a S&W M&P 9mm 3.6/4.0/4.25 - leave barrel length in notes, and will make the holster fit with a Crimson Trace laser.

Try Fobus. I know they have one for the fullsize M&P with a light or laser...

Cheers!

Try Crimson trace website. They used to sell holsters that worked with their lasers.

Also try Crossbreed or Vedder.

Try Wright Leather Works in Ohio. They were able to do a custom version for my M&P 2.0 Compact 9mm with a Crimson Trace 209 attached.
Reasonable prices, quality leather and great workmanship.
