Slide mounted Holosun

Post by John McCormick on 12/8/2017, 11:46 am

Anyone have any longer-term experience with a Holosun dot, slide mounted on a centerfire 1911? Looks like they've held up okay for 500 rounds or so, but how about a year or two of use, say?

I suspect my Holosun of causing problems on my 52. Shots are going off call. I changed scope without changing mount and shots went back on call. I have not put it on a different pistol yet to verify but suspect it is the culprit. Going into storage for awhile.. Problem was around 500 round count.

I've been using one on the slide of a .38 Special 1911 with good results. Probably 800-1,000 rounds. I have the Holosun on a Kodiak mount from Fred Totts. The factory mounts are quite weak, specifically the cross bolt. I've had two of them break.

I've been trying a holosun slide mounted on a 45. I've got well over 1000 rounds threw it and except for some initial battery tray issues it's holding up better than expected... I'm even growing to like a 2moa dot...

I think you nailed the problem with my Holosun. The cross bolt is weak. I would call that a failure.

Fred Totts gets, I believe, $60.00, shipped, for a base. His do not break. Same one fits the Aimpoint Micro.

His email is: ftotts@neo.rr.com

If you email Joe at Holosun, he will probably send you a replacement factory bolt. He sent two of them to me at no charge.

Do these have image reduction like Ultradot scopes do?

Thanks for the discussion. Re "minifying", most of my UD scopes do produce a slightly reduced image. But my one Holosun doesn't. And with respect to unexpected shutdown, my Holosun hasn't, so far anyway, but the UD on my wad gun did yesterday. The battery cover had loosened slightly.

Other than the initial issues I had with the battery tray, mine has performed well.

I have a couple more questions. Are you guys using the scope as is, or did you add sun shades to it? I'm wondering about keeping the lenses clean, and if the shades help. 10sandxs, are you using the factory base/mount with yours?

graphite tubes with a 30mm UD cap so I can add the UD filter.

May I ask who made the tubes ? Cool idea with virtually no weight.

I made my own shades based on what someone had posted here, using carbon fiber tubing and golf club shaft epoxy. For about $30, you can make 20-30 of them.

I bought a one meter piece of tubing and the epoxy on Ebay. The size of the tubing is 30MM OD and 28MM ID. I've made them for an Aimpoint H-1, a couple of Holosuns, and 3 Primary arms (made by Holosun) sights.

Besides the Kodiak Machine bases, Fred Totts also makes and installs aluminum shades that are press-fitted.

tubes are commercially  made. I just found the right size and cut them them to length.. held on with golf shaft epoxy.

cut the tubing with a 6 "cutoff wheel mounted on my polisher.



Be careful about splinters with the graphite.

My thanks to jglenn21 for his information on the tubes.

A friend and I cut them to length using his lathe and rigging a Dremel with a cut-off wheel.

Well, after about 2500 rounds the holosun is giving up the ghost.  my groups migrated from the x ring to the 7 ring (50' timefire target) at 10:30 in about 15 rounds.  At first i thought it was me, but then I shot a few groups from a rest, nope, its the dot. I went to adjust and started 5 clicks right and 5 down.  it went five right, but no change in elevation...

on the plus side, holosun was pretty good to deal with and is sending a shipping label... we'll see what they do about the dot once they get it.

on to the vortex crossfire, and a 90 degree frame mount...
