I have owned both the Vortex Strikefire and the PA AD-MDS. I returned the Strikefire and still have the AD-MDS.

The Strikefire had too much parallax error for me. Most people won't notice it and in fact don't check for it. So, it would probably work fine for you.

A 2MOA dot at the correct brightness is not any more difficult to pick up than a 4MOA dot on a rifle. This is because of the stock and cheek weld. On a pistol it's a completely different matter.

Therefore, I prefer the 2MOA dot. When I do take precision shots, the 2MOA is better.

Both companies have the same level of quality customer service. I'm a huge fan of Vortex and have two of their higher end scopes. However, when it comes to the low end red dots, the PA AD-MDS is the best I've personally used.
