Red dot, Green dot

As far as a Reflex sight, cannot add any input but on my Ruger MRIII Hunter, I had a Red Dot scope on it for a time and loved it....spot on and has the red/green dots on 5 different settings.
Some you will find, only come with the 5 moa (dots) and they will basically cover a pop can out at "about" 30-40yds.
My preference on a (dot), would be something (smaller) than a 5 moa dot.
As far as color, I use both the red and green when I had it on the MKIII as per background color and or, target color/background and time of day shooting. (cloud cover/sunny, etc.,)

 

I put an inexpensive Simmons red-dot on my Mark III 22/45. It isn't pretty but it is accurate. It has a 5 moa dot and it works just fine out to about 25 yards, after that it is like zane says, it covers up your target!

My 12 YO granddauaghter likes shooting it but gets kind of bored with all the bullets going into the bullseye. I got to where I am setting up shotgun hulls and old rifle brass as targets for her.

 

Several of the Old Guys have various low cost reflex red dots on their pistols. Three of them have failed and been sent back for warantee repair. My suggestion is save a little more and buy a quality sight first time. For target work you are going to want as small a dot size as possible. As Zane says the 5 moa dot is just too large for target work. Get a sight that has adjustment for intensity (brightness) of the dot. The Ultra Dot/Match Dot seems to have a big following and a lot going for it. It will be my next purchase of a red dot when that happens. The red dots are great for those of us with old eyes and really enhance the shooting experience for us Old Guys.

I do know what you mean!
And also as far as my experiance, I like the larger "tubes" on them for the fact of my "old-age" eye sight. I have the Tasco Pro Point 40mm and it is much easier for be to get the sight picture quicker then the smaller dia. tubes.

 

i also like the smallest dot available , but i prefer the smaller sight , i put the doctor sight on my browning

 

Nice looking setup and like the holster as well!!!
