Hi,
I've found the red dot sights incredibly fast in bowling pin match competitions. I've found also that they are much faster in the deep Georgia deer woods where I've handgun hunted for years with my S&W .44 Magnum topped by a 1st generation Bushnell Holosight that's been on this revolver for many years now.
With the Holosights, the dot seems to magically appear on your target and you don't have to have perfect eye alignment behind the viewfinder like you do with a scope!!! Basically, if you can see the dot, that's where the bullet is going exactly!
NO MAGNIFICATION EITHER, thank goodness!!! Thus, the target appears like it does naturally, so if a deer, bear, hog, whatever is moving quickly through dense cover you can swing with the target, keep BOTH EYES open and squeeze off the round into a perfect little opening in the foliage!
Thus . . . twice in the past few years I've dropped THREE deer back to back. Once in a fresh clearcut on a ridge, and the other time in a thick bottom with three deer came down the same trail! In the clear cut, after I dropped the first one the second took off on a full run broadside. I swung and had a perfect sight picture. The deer hit the ground like someone had flipped a switch and never moved at all! Distance? I paced it off at sixty five yards. Then the third deer rose in the clear cut to check out the commotion! Ah the memories!
I also keep a Holosight on my AR-15. For fast action competitions AND for moving targets in real world situations, you can't beat a great red dot sight!
Here's a closeup of the rig, on top of the hide from a Piebald Whitetail buck I took with this set up a few years ago.
And with an 8-point buck I took with it last season . . . with a heart shot.
Another Holosight on my Ruger MkII Target pistol. Great squirrel and small game rig, and I once knocked down all six pins in a six-pin table in a bowling pin match (at the regulation 10 yards), in a blazing 2.20 sec. I've never been able to touch that time. These Holosights are "scary-quick!"
None of my Holosights have ever lost their zero either. Kind of pricey, but worth it, IMHO.
