Front Blade Problem

I have purchased a few thicker front blades for my CM84E and I decided to use them. I was happy to use the factory width but I prefer something that is thicker. Then I find out that a few of them are not level at the top. Maybe 10 to 12 degrees off too high on the left, or right. Sounds not a big deal but at 50M my shots are all off (nice grouping though!).

I wonder what I should do, other than sending the blades back to the seller and request for replacement.

Here are my other chocies.
1. Have a gun smith shave off the top of the blades so it is level.
2. Use a masking tape to mask the unequal top of the blade, then paint white on the blade. Tear off the masking tape, then when I aim I just aim the top of the white paint, ignoring the top of the blade itself.
3. Rotate the compensator so that the top of the blade is level, but in this case, the rest of the blade will not be perpendicular. Shoot anyway and ignore the rest of the blade and only concentrate on the top of the now level blade.
4. Put a tiny piece of paper between blade and compensator so that blade cannot be totally screwed in, thus making the unequal top level, again, the rest of the blade will not be perpendicular.
5. Shoot and aim it with the cant in mind. Adjust aiming mark to compensate for the cant.

Currently with the cant I get a nice grouping but it is all on the upper left corner of the target, all outside of the 1 ring. If I rotate the compensator and make the top of the blade level I get better results, but I don't feel comfortable because the daylight created by the front blade and the rear sights will be unequal: either the right side has more light, or the left, and this does not take into account that they are not rectangular in size.

Advice please?

The one thing I learn from this is that...even with Morini, the manufacturing quality is not perfect, and now I have the first hand experience of shooting cant and see how a grouping "moves" away from the target.

Please bare with me, this is only the eighth month that I have ever picked up a firearm. None of my firearm friends know what to do with a target pistol, let alone a free pistol.

return to retailer for replacement?

Minor sight alignment can be achieved by using a packing under the low side of the foresight.
I cut a stick-on target patch to thin strips, and stick them on to the bottom edge of the sight left or right side of the screw hole.
This will tilt the sight into align. I have never needed more than two layers to get it right.
Stick them to the sight not the base, then you can change sights without any changes once set the first time.

Gunsmith?

How about a flat Swiss file (points file?) and do it yourself. File at a slightly downwards angle to the front so as not to pick up glare. Shouldn't take more than a few seconds, but the above idea is even better.
