Appreciate all the responses. Will try that elevation adjustment to both limits and give the plastic shims a look.

I was sighting in a Holosun 407K that I purchased recently. Have it direct mounted to my Sig P365 X Macro. The optic initially started out low and left by a fairly significant amount. As I was adjusting to sight in, I reached the limit of the elevation adjustment. So what are my options at this point?

Installed new grips and magwell (Lok Grips Gridlok) on my Shadow 2 SAO. Ran it at the range this evening for the first time and had some feeding issues. Felt like the magazines were not seating well. I’ve got stock/OEM base pads on the mags. Lok Grips website says the OEM base pads will work with their magwell but may need some minor alterations/adjustments. Can anyone clarify what I would have to do to get these to work?

Update, about 7months now with the Q5SF…never changed any of the springs. Up until last week, was only running 124gr brass without any issues. Tried 115gr last week on a whim… no problems. I’m thinking it just needed some break-in.

Thanks all. Appreciate all the responses.

Can someone give me the recommended/ideal torque value for screws that secure a red dot sight?

Apparently there are quite a few others that you may consider unlucky. https://youtu.be/naLN3ehiYik

Planning to swap my Vortex Venom for a Holosun 507C that I have on another pistol. The video I referenced pointed out that the Venom in particular is likely better suited for mount on a non-reciprocating rail. The 507C is a heartier optic and will likely hold up better. I might have just reached the Venom’s limit…may have to send it back to Vortex for evaluation if I can’t zero it on my Volquartsen (22LR, pic rail mount…so it will be as gentle as can be on the optic).

Different ammo…initially I thought this might be the issue after others suggested, but now I’m thinking otherwise after seeing this: https://youtu.be/4HXhx1JbYx0

This isn’t helpful at all. What’s your point about the mounting of the optic? If the screws aren’t loose and there is no sign of movement of the red dot sight, then why would you think the mount was bad?

All were zeroed at 10yrds. All were shot that day at the same distance. They were all low about the same distance. It was fairly significant but I don’t know exactly how far. I’m taking 2 of them back to the range this week. I’ll post a pic of my targets.

Will do. Thanks for the idea.

Is it common to need to re-sight in red dot optics often? On a recent range trip, I noticed the red dot sights on 3 of my pistols were not zeroed, whereas they had been fine the last time these 3 were fired at the range maybe a month ago. The first is a Holosun 507K on an Sig P365XL. The second is a Vortex Venom on a Walther Q5 SF. And the third is a Vortex Venom on an HK VP9L.All 3 have the optics mounted on the slide. I haven’t noticed any issues with the mounting screws loosening. None of them were dropped. They all seem to have a consistent issue. Point of impact is lower than point of aim, by a significant amount.At first I thought maybe I was just having a bad day with accuracy and my trigger control was haphazard. But my wife who is a decent shooter had the same issue to about the same degree. So there’s a chance we were both having a bad day with accuracy, but I really doubt it.What’s also strange is as I attempt to re-sight in the optics, I reach the limit of the optic in how far I can adjust. Any thoughts/help is much appreciated.

Update…went to the range today. Ran 100 rounds of 124gr CCI Blazer brass thru my Q5 SF without a hiccup. It ran flawlessly. I didn’t try going back to the 115gr because I was so pleased with the performance of the 124gr. I guess I’ll just stick to 124gr or higher with the Q5. Appreciate all the responses and advice. Jon

Can anyone point me in the right direction on where I can find a stronger extractor spring?
