Not a good idea with a Holosun 407. You can easily turn the dot off by pressing the + and - button simultaneously with a finger.
Not on a 507 K or C
I did it one time with a 507K X2. I then put it in lock mode so that doesn't happen. It also means you can't adjust the brightness without first unlocking it. I then went to the 407K X2 for the bigger dot so I can find one setting and leave it on that. With that said, it's not the problem that TRH makes it out to be.
I've been using a 507C & K for better than 2 years even sleep and laying on the pistol and optic and I've never experienced the problem that you describe.
I never lock it as want to be able to adjust the brightness as needed instantly and have never experienced the problem as described
