I really like the Crimson Trace Laser grips.
I have them on My Kimber .45 - my Glock .26 and these were
on my XD.
When I bought XDm I called CT and asked if the CT had grips for the XDm ..
Long story short and in my words not theirs ..
They do not make CT's for XDm yet
And do not know when they will.
They said that with the XDm having 3 sized grips they could not control which grip the customer used ... etc. etc.
So I measured the XD grip and it was the same size as the middle grip on the XDm (the one that came on it from the factory).
I installed it on my XDm and it fits great.
I really like shooting with the laser grip - I'm very accurate (for me) shooting with it.
Several hundred rounds and it's never lost it's point of aim.
I love it.
