M&P40 w/ Ameriglow FS

[rzhabr]

Did a quick search on this and found a few people asking the same question but no answer(s) to the question.

After installing the Ameriglo front sight on my M&P40 I am no longer able to do a 6 o'clock hold. I now have to smother the target which doesn't allow for a great sight picture. Is there a rear sight, other then the stock one, that will allow for a 6 o'clock hold again?

Let me be more specific.

For any M&P40 owners out there that have replaced their front sight with an Ameriglo and are no longer able to do a 6 o'clock hold. Have you been able to find a replacement for the factory rear sight that allows to a 6 o'clock hold?
