Hello all, I own 2 pistols for defensive carry, I purchased one specifically for concealed carry, and use the other for open carry. Don't get mad, but the choice for concealment was: Springfield XD40 4inch V-Ported My open carry pistol is a Glock34 9mm. I am in the process of adding XS Big Dot tritium sights to the XD, which will cover me for day and night self defense scenarios when carrying my concealed gun. The problem that remains is my open carry gun, the G34. I was originally going to do the same, until I stumbled upon the jpoint red dot. I have to admit, I was blown away the first time I saw a pic of it mounted on a glock. So here is the dilemma, spend about a 100 bucks on night sights and only add the ability to shoot in low light, or, add a red dot sight and not only get low light aim-ability, but also add sniper like marksmanship to my mid and long range target engagements.(slight exaggeration) OK, so here is the real topic. If I am going to use a red dot on a pistol, it needs to cover 3 things at a minimum as far as I can figure. 1: It must be parallax free! 2: It must be small. 3: It must be reliable and intuitive. Which are my best options to cover the above 3 requirements? And price isn't really an issue, because you cant put a price on having the most advantages over the bad guys. So far, as of right now, I am really leaning towards the C-more STS. Now, I'm not too interested in opinions unless you have personal experience either owning, firing, of carrying a pistol with some kind of red dot on it. If you have pure facts or statistics those are also welcome. For those who reply with valuable feedback, I thank you in advance.
