Holosun 407K vs 507K

[GJM]

The Holosun 407K arrived today.

Sounds simple, right? But not at my house!

Checked my mail and saw a notice that the USPS had delivered the optic to my neighborhood cluster mailbox approximately 30 minutes earlier. Walked to the mailbox and opened it. The package from Holosun was inside.

BUT . . . the asshole mail carrier had placed the package inside my box by opening a front panel/framework around my mailbox and a stack of nearby boxes, then closed the panel. So when I opened my box, I could see and touch the Holosun package/box, but I could not remove the package through the front door because the package was larger than the opening!

So, at the sacrifice of the skin on my hand, I reached into the mailbox and ripped the outer package off the optic. Only to find a smaller package. Which I ripped apart. Which contained the sturdy case containing the optic and accessories. Which would still not fit through the opening of the mail box. So I removed the case lid. But the main part of the case would still not fit through the mail box opening.

But I managed to turn the case up enough to remove the optic, instruction sheet, mounting screws, optic tool, etc. and get them out of the mailbox and place them into my pocket. I then reinstalled the lid of the optic case and closed the mailbox.

Then I walked back to my house, procured a pen and a sheet of paper, along with some scotch tape and wrote a note to the dipshit mail carrier advising him he needed to remove the case from my mailbox and place it in one of the larger boxes designated for packages so I could retrieve my optic case.

I considered using colorful language challenging the mail carrier's intelligence and heritage, but decided in this age of perpetually offended and sensitive people, I might be subjecting myself to a federal crime, so I refrained from voicing my full opinion of his service. Walked the note back to the mailbox and taped it to my mailbox door.

I returned to my home to install the optic on my Sig P365XL. My left hand looks like I spent the afternoon neutering bobcats from all the work I had to perform inside the mailbox.

Installing the optic on the pistol was straightforward, using denatured alcohol to thoroughly clean the screw holes, and applying Loctite 242 to the screw threads upon installation. Screws were torqued to 15 inch lbs. per the instructions, using my Wheeler Engineering torque wrench.

Then I discovered that the optic had shipped without a battery!

So it was off to town to a CVS drugstore/pharmacy to purchase a CR1632 battery. I arrived at the drug store a few minutes later and walked across the parking lot to enter the store when I realized I had failed to wear my face mask. Returned to the truck, retrieved my mask, put it on, and went inside.

Located the correct battery relatively quickly and got in line (at the prescribed proper social distance mandated by numerous signs and tape markings on the floor). Three cashiers on duty. One each on separate checkout stations. The third cashier appeared to me lost, dazed, or in a coma. Short wait, right?

WRONG. After two (2) separate price checks on register #1 and numerous calculations determining the value of about half a dozen discount coupons on register #2, the two 300lb. + female (I ASSUMED their gender) pinheads departed the store.

After four tries of attempting to get the bar code scanner to recognize the bar code on the package containing the battery battery I was purchasing, I was on my way home.

Total time for project: One hour 35 minutes

Total time actually spent removing the rear sight from my Sig, prepping the screw holes, installing and torquing the mounting screws, installing the new battery, reading the optic operating instructions, and adjusting the dot intensity on the optic: About 10 minutes.

I will get it to the range and get it zeroed this weekend if possible.

Perfect example of why most instructions say “professional gunsmith installation recommended.”

Just wait until you finally get the packaging and find the battery stuffed in the bottom of a little slot in the foam...

Jesus. That never occurred to me! Well, if that's the case, I already have a spare battery!

The battery that came with my Holosun 507t was junk. It was dead 3 months later.

The battery that came with my Holosun 507t was junk. It was dead 3 months later.

My 508T came with an Enigizer that lasted about 8 months, and that was on a pistol that was stored 5 days a week so the dot was turned off. Not good.

IF I discover that there IS a battery in my 407K case currently residing in my community mailbox, perhaps it would be better to designate it for a less critical application I might have around the house. Not worth taking a chance on, I think.

Batteries are a hidden devil. Lots of junk out there. Lots of counterfeit stuff on Amazon.

FWIW, the Duracell in my 407K is still going strong after 30 days of daily carry at 10/12 brightness.

Based on what I have seen posted on LF all I have been running is Duracell batteries.

Just getting around to using my new Holosun 407K mounted on my Sig P365XL, and have encountered a problem.

I have adjusted the intensity of the dot on the optic according to instructions in the Owner's Manual, and then used to the locking feature to lock the intensity at the desired level.

I have also adjusted the dot to go into the "sleep" mode after 10 minutes, as instructed.

Both those features seem to work fine.

What DOES NOT appear to be working correctly is the "Shake Awake Technology".

According to the manual. the sight will "instantaneously wake up and turn on with any motion detection to the last saved intensity setting"

My issue is that my optic does not respond as described. When the pistol with the optic mounted in placed in a stationary position for approximately 10 minutes, the red dot "goes to sleep" and shuts off.

When I pick the pistol up to use it, it takes several seconds and a considerable amount of shaking before the dot will turn back on. It always turns on, but the time delay is considerable.

Is this an operator error? Am I missing something?
