Hello wanderer.....I can't see poop either. First off, what will you be using the red dot equipped pistol for? And at what distance? At 100 yards a 2.5 MOA dot covers 2.5 inches....a 6 MOA dot covers 6 inches. At HD/SD ranges it simply won't matter.

I only ask because if the planed use is for HD/SD, the distances will probably be 50 feet of less. At 100 yards the dot sizes are 6" vs 2.5". At 37.5 feet the dot sizes are .75" vs .3125.

Again, if its for SD/HD either dot size will be just fine. On the other hand, if you're trying to shoot a gnat in the eyeball at 50 yards, then the smaller dot size would the way to go.

Here ya go, my 4" and 5" with Deltapoint Pro and Vortex Viper......they make my life MUCH easier...don't have to worry about being able to see the sights any more....the 'red dot' is ALWAYS in focus.

 

I'll add that the larger dot is easier to see and I find it would be my choice for quick acquisition of a fast moving perp..... but, the smaller dot would offer more flexible use if you like to throw in a little target shooting. 1917

 

You already got all the answers you need.........I went with the 6MOA and I don't regret it.

 

A 6 MOA covers 1.5 inches of a target at 25 yards. I can't imagine a real need to go smaller.

Remember, the size of a dot does not change the accuracy of the sight. Even if a dot covers a person's head, if you center it on the head, you will hit the center of the head.

I had posted some comments on another thread regarding 3 MOA vs 6 MOA. In my own experience (YMMV), my accuracy, especially at 25 yards or more, is noticeably better using a 3 MOA vs. the 6 MOA. You might be right when shooting at a target as wide or wider than a human head that is covered by the red dot. But there's a lot going on behind that red dot and I just don't think you'll be able to dial in the amount of precision with a 6 MOA to say that the exact center of that 6 MOA red dot is going to be the point of impact. Yesterday, several of us were shooting at plastic bowling pins at 25-50 yards. The 3 MOA red dots were the consistent winners.
One other thought: My Vortex Venom 3 MOA red dot was considerably sharper, crisper, brighter and more precise than the other 3 MOA red dot in the group that cost 1/2 as much. "You get what you pay for." But no matter what the cost, I'd take the 3 MOA over the 6 MOA every time (as long as the dot is crisp, bright and sharp).

 

6 MOA is much better than 3 MOA in the sense that the dot appears rounder and it experiences less emitter starburst. Besides the dot differences, the 6 MOA is great under daylight use if you have okay eye sights. Just crank up the brightness and the center dot will appear much clear than a 3 MOA dot.

I have a couyple of Trijicon RMR type 2s. One is the 3.25 MOA and one is the 6.5 (IIRC).

At distances under 25 yards... I'm not sure I can even really tell the difference.

Full disclosure: I have astigmatism that causes starbursts so both just sort of look like "that red amorphous blob" in the middle.

For more precision, go small dot. For faster acquisition, go large dot...

 

Also try looking at a bigger dot under sunlight. The sunlight will wash away the starburst, and leave you a bright dot even if you have minor astigmatism.
