I spent a lot of time to find a holster to accommodate my LCP Max with lasermax grip sense. Several holster makers claimed to work but didn't. I settled on the IWB holster from Alabama Holster company and when the holster intermittently turned off the grip sense, I returned it for a fix.
Now, I'm happy with the Alabama Holster company IWB. But I'd contact the owner to confirm that he is still accommodating the grip sense...I got the impression it was somewhat of a pain to deal with.
