Do the steel frame .357 mag and 9mm LCR's have the same external dimensions as the aluminum frame .38 +P LCR?

I plan to get a 9mm LCR in the near future (my LGS is trying to find one). I plan to mount a LaserMax Centerfire laser on it. It mounts to the trigger guard and to the cylinder crane screw. So I need to know if Ruger used the same frame and cylinder length on all LCR's or if the .357/9mm has a longer cylinder (and therefore longer trigger guard to front of frame dimension)..

Does anyone here have access to both a steel frame and aluminum frame LCR to see if these dimensions are the same?

The 357 & 38 guns are the same, and use the same holsters.  I am not sure on the 9mm though.

Thank you,
That's what I needed to know. Everything I've read says the 9mm is built with the .357 frame and cylinder blank. So they must all be dimensionally the same.

That saves me a lot of headaches.

Yeah the 357/9mm/327 all use the same stainless frame.  The 38 uses aluminum and I think the 22's do as well.
