I like it. I'll rephrase Well Armed's post because I really like it.
9mm vs .45 ACP.
Bear guns/.44 vs .45 vs. 357. Never mind long arms.
Double action vs. single action.
Pistol vs revolver.
High cap vs pocket pistol.
Pocket carry vs appendix IWB.
There are other variations of the dead horse-type thread but they make some wonderful discussions and make folks think. I like them all. And, guess what, I have an opinion, too!
IMNSHO, the problem with red dot sights is two-fold. First, it is really hard to argue that they have any real value in a defensive, concealed carry handgun. You can argue until you're blue in the face about how much easier it is to get on target and make accurate shots but that's range talk. Now, if you're a security guard, LEO, and probably even a Soldier in the field, with large weapons at the ready, I'll agree that RDSs are valuable. With constant practice, a skilled warrior with an electronic device on his weapon is not to be sneezed at. Or do so at your peril. But for the average citizen, the technology is not worthwhile. Your defensive distances are up close and personal and finding your red dot to place on your target is a complete waste of time. Point shooting is a far more valuable skill to inculcate for saving your life or the lives of others. But
YMMV and obviously there is wide disagreement.
The second issue is concealability. If you're concealing a service-sized weapon on any kind of belt holster, and lots of folks do this, more power to you. The RDS doesn't change your concealment tactics much if you're comfortable with a large pistol on your belt. BUT! If you're concealing J frames, pocket/micro pistols, or even just compact pistols in any caliber the art of concealment is lost with any electronic device you can place on it except, perhaps, a laser under the barrel. (Not for me but those are concealable.) The technology is wonderful and has its place but not in the world of concealed carry for most folks. As always, YMMV.
Not to be a jerk about it but I practice what I preach
