Hi all,

Waiting for a new Holosun HE507 to arrive and contemplating/doing my homework for the installation on the MOS G19 slide.

So far I heard/seen two very different approaches to attaching it - the Holosun manual and a guy from my LGS insist on using a torque screwdriver to tighten the screws to specs, while a bunch of online/YouTube "tutorials" show the same process using a little tool provided by Holosun in the box. I am confused a bit - the Holosun manual calls the tool "T10 Torx wrench for screws". Does it actually work as a real torque tool? And if it doesn't - how come people install the sight without a proper torque settings? Most likely a very ignorant newbie question - but as always looking forward to your feedback.

No, it's just a torx wrench not a "torque" wrench.

If you don't have a torque wrench you need about 15 inch pounds, that's hand tight with about 1/8" more. You do not crank it down. Let the Loctite do it's job and install witness marks with paint.

Torx is the style of screw head, like a Philips or slotted. Torque is how tight it needs to be. You should follow the correct torque specs for your torx screws.

LOL it explains a LOT - thank you!
I will definitely use a proper tool.

I’ve had a Fat Wrench for 3-4 years now. Works well and wont break the bank.

Alternate tightening screws, some on this side, some on that.

You want it attached evenly and securely.
Test fit it first.
Don't forget some type of thread lock.

Buying a torque screwdriver is a small price to pay. Improper torque is no bueno. You can strip out the screws if too tight; the sight can come loose if not tight enough. Get the Wheeler FAT torque screwdriver and pick up a T10 torx bit at Amazon and you'll be good to go. Re-torque the screws every 3-500 rounds after installing it.

I mounted scopes and did other very basic gun stuff for years without a torque wrench without any problems. But for the last 10 years or so I use one. Gives piece of mind that the job is done right.

Amazing - because this is exactly what’s arriving from Amazon by end of day. I am happy I picked that one yesterday even before I asked the question. Did it based on the LGS guy’s assertion I will need a torque driver. And then I saw some videos where people were using a manual wrench and got confused.
Thank you!

Turn it until it gets really tight,,,,then gets easy...back off 1/8th of a turn and you're set.

You did good. It beats the heck out of guessing.

 

[doctorvfs]

All done and done.
Now off to the range we go.

Far more important is to not bottom out the screws. Many of these screws are a couple thousands too long. You may need to take a hair off the screw in order for it to go in properly. You can feel the difference between a good torque and a screw bottoming out. The tool that comes with the holosun enables you to get all the torque you need.

This. Remove the extractor plunger assembly while you install the optic. Make sure it drops through with the screw tightened. I've also seen the left side too long and will chew up the first few threads.

I have a pretty extensive set of tools and overall I would recommend the fix-it-sticks for a lot of jobs. They offer 2 types of torque specific tools; adjustable torque and torque limiters. Both have attachments that allow you to use torx, allen (hex key), socket and crows foot attachments. They are extremely well made and compact. I have a set I leave at home, a set I leave in my range bag, and a set in my go bag.
I have a set of larger torque wrenches as well, and many of the jobs on your handguns can be done with a 1/4 drive torque wrench with the appropriate settings. I am not familiar with some of the recommendations here (such as Fat Wrench), but have had bad experience with other models that were not "quality" tools. I hung around professional gunsmiths and mechanics as a kid and they all bought "quality" tools, especially for items like a torque wrench/limiter.
I really like the fix-it-sticks torque limiters, color coded, well made. Cannot recommend them highly enough. If you are building a capable stable of tools they would be a worthwhile purchase.
I have done a lot of work where I should have used a torque wrench/limiter and did not. All metals in all uses is not created equal, and I have the trash bin of parts to prove it! The grip screws on 1911s would be one of my earliest lessons! Moral of the story - a torque limiting device is cheaper (and faster) than a repair due to over torquing!
Hope that helps!

Yes it does help! Thank you.
I also had issues installing 1911 grips and now with the red dot I am sure appreciative of any insight and plan to have proper tools.

This thread convinced me to get the Fat Wrench. I've seen it recommended in several arenas for years now.
