My question for you is after you adjusted the Red Dot on your pistol. Do you really believe it made the pistol quite a bit more accurate?
The reason I'm asking is I've never added any kind of a scope to any of the pistols I have. If you say the pistol scope combination is much better than the factory sights? I'm going to give it a try. At this point what do I really have to loose? I mean I already have the scope and also have one or two of my pistols that a scope can be mounted on.
I guess it all depends on how you define accurate.
I use the pistol for rapid fire target shooting. The red dot allows me to quickly put the target into my shooting zone. I usually hit the object that I'm shooting at, but you may be talking about a 1 sq ft area. Hitting the target is the object, it doesn't have to be a dead center shot. The max distance per shot is short, maybe 45 ft at the most.
If you are wanting hunt or need to hit dead center then I would go with a "cross hair" type scope.
But, you have the scope, you have a couple of pistols that you can mount it on. Heck, try it out. It make plinking more fun.
