## Questions & Answers

**Q: Will this plate work for a M&P full size 1.0?**
A: This is not a plate but a shim (thicker at one end than the other) that is specifically designed to alter the red dot mounting angle.  This part may be required if the red dot range of adjustment isn't enough to reach the bullet impact point.  To mount the red dot you will probably need this part:

**Q: How do you install the shim?**
A: 1. Remove red dot sight (RDS) from base. 2. Place shim in between RDS and base. If bullet was impacting low, then install thick side to rear. If bullet was impacting high, then install thick side to front. 3. Re-install RDS on base with shim sandwiched in between. 4. Torque to spec. 5. Zero RDS at the range.

**Q: The shim on umtactical's site shows 8 holes in the shim so you can install it 2 ways. the picture on amazon only shows 6 holes. is this an old pic?**
A: I dont know. The other two holes would be for mounting it to raise the dot, I guess? Mine had 6 holes.

**Q: How many inches will 1degree shim raise or lower site picture?**
A: I don't have any specifics, but I have only shot my M&P 40 with an optic with the shim. I seem to shoot on target from 3 to 20 yards on variable moving targets during league. I have it sighted in at 10 yards with no problem to zero the elevation.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Totally solved my POA/POI issue on my Walther Q5
*by G***F on December 6, 2019*

Have a Walther Q5 with a Vortex Venom optic on it. Was hitting substantially low until the Vortex customer service folks suggested this product. It totally fixed the problem AFTER I realized that the shim is a shim...which means that one end is higher than the other. Once I figured out I put it on backwards, everything was perfect.An inexpensive solution to a big frustration.

### ⭐⭐⭐⭐⭐ Fixed Vortex Venom Elevation Issue
*by S***D on August 9, 2020*

I purchased a Vortex Venom 3MOA for my .410 turkey gun, but was dismayed when the elevation screws bottomed out and I was still patterning 6" below the bullseye. A quick search online revealed that many folks have experienced this same issue with their Vortex Venom sights running out of elevation adjustment. Vortex customer service recommends this product as the best fix for the lack of elevation. Received this shim, which mounted perfectly on the provided base and is thin enough that you can continue to use the stock screws with plenty of thread engagement and the registration points in the base still securely engage the sight to maintain zero. Place the thick end of the shim towards the rear if you need an increase elevation or to the front if you need to decrease. Quick and easy fix. Now I have plenty of elevation adjustment if needed. Highly recommend this as a simple fix for an issue Vortex needs to address. For the price, Vortex should include this shim with all of their Venom sights.

### ⭐⭐⭐⭐⭐ Fixed Vortex Venom Elevation issue without the shim
*by A***N on May 23, 2021*

I too bought this shim and it did fit the hole pattern and the factory screws were indeed long enough. I ended up not needing the shim to fix my elevation problem on my venom red dot. I had the venom mounted on my MK III 22/45 and I ran out of elevation. The gun was hitting about 3" low at10 yards with the elevation screw turned all the way up. After I ordered the shim I called Vortex customer service and the guy told me to try running the windage screw (not elevation) all the way to the right then back all the way to the left and see if that worked. I guess some how this action can work to recalibrate the settings. Well this worked like a charm for me. After doing the recalibration, my first couple shots were an inch or so high. Plenty of room to dial down the dot right where it needs to be. Try this before you buy the shim. If your mount has the 4 little locating pins on it to mate up into the venom, the shim with the thick end will prevent the pins from mating into the bottom of the venom. Not a big deal as the two front pins will still hold it in place along with the two screws used to attach the site to the base.
