The LG-437 CT laser on my PM9 dims after each shot, and comes back to full brightness only if I reactivate it (finger off the button and re-gripping).
It does not dim if I'm just holding the laser on, so in my opinion it is not a low battery issue.

Has anyone experienced this, and more importantly, will Crimson Trace repair/replace it?
I'm waiting to hear back from CT, they responded to an email about the battery replacements but ignored the inquiry about this dim laser issue.
