Home Forums Hunting & Shooting Handguns reflex sight maxed out

I just installed a Holosun 507c on a new Smith model 69.(44mag)
I used an allchin mount to keep the sight as low as possible.
I am shooting at 25 yds off of a rest and with the sights verticle adjusment maxed out i am still 10" high!
Anybody else have this happen? I was shooting both special's and magnums, both 240gr.

Yup, same here. I got a tapered shim and that cured the proplem. I am traveling and do not have or remember the what and where details. I'll look for the details when back home in a few weeks. In fact I still have the shim if you want it. I traded the m69.

Just found it.

This is interesting as I was just about ready to use the same mount and sight on a S&W M686 .357. Now I'm not so sure I want to do that.

well thanks for the info
I just ordered it and i will report back on my results.

I had the same problem with my Model 69. I returned mine and put a Vortex Venom on which sighted in OK but I liked the Holosun reticle much better.

I too like the dot and circle reticle on the holosun

Mine worked out just fine.

Looks good. Looks like you're shooting matches of some sort? Probably a .38 load? Have you ever zeroed that with heavy bullet full house magnum ammunition?

ICORE.

No I haven’t shot any heavy magnums with it. I’ll see what I can find and try them this weekend.

Just checked and all I have are 125 grain Gold Dots in magnums. Up until recently I’ve always had a 44 if I needed more gun. Gotta rethink things now I guess.

Same with my Vortex sight on a 22/45

Well i finally got the tapered shim as recommended and YES IT SOLVED MY PROBLEM!
So thanks to mjac my revolver is shooting to poi.

Glad it worked for ya. Enjoy!

I’ve used three EGW mounts, a 1911, a Glock, and a S&W 629 classic 5”. I haven’t had any issues getting them zeroed. The Glock was almost dead on at 25 yards when I first shot it, only about 2” to the right if I remember correctly, wasn’t much.

I had this very issue today while trying to sight in a Holoson EPS Carry with an Allchin mount on my M69 using 300 grainers at 1150. I'll be trying the shim.

O ne thing i found out is you will need longer screws than those supplied by Holosun. The mount from allchin comes with longer screws (6/32) but the head diameter was to big.
I had to machine the head diameter down about .025".

Kinda makes me think I may go with the EGW mount.

or not buy a model 69

Good to know. I'll comb the hardware store first I reckon.

For reference, I had the exact components on my m69 as did the OP. The shim did indeed cure the problem.
However before I went the shim route I tried a Weigand mount and still had the problem.
I should add that I have Weigands/Holosun's on two GP100, a Security Six and a couple of Blackhawks with zero problems.
So in retrospect, I believe the red dot on a M69 problem lies with the mounting surface on the M69 and not the Holosun.
And btw, I read about the shim fix on the Pro Board site.

I want to put a dot on my 686 Pro Series 4" .357. The Model 686 is an L frame like the M69.

MOGC,
The long gone M69 was my only Smith. Sorry I can't help with your L frame.

Worst case scenario, buy the shim $12.00 bucks!
I also have a weigand scope base but i think my sight would of sat way to high if i used it.

You're right, it's not a huge deal. If I can avoid shimming by using a different mount in the first place that would be preferable. If not, I'll shimmy.
