For open sites I love the Advantage tactical sight they are easy to acquire and I can use them without my glasses.

I'm intriqued

I have heard good things from those who have tried that kind of system.

Not sure it would help those of us with aging eyes though. Our issue is old eyes can't bend three different planes into focus.  When you are young, you have a crisp front sight, a good rear sight and a slightly fuzzy target.  Older you get, the blurrier the target gets and fuzzier the rear sight gets.

I will say this as far defensive handgun sights if I could get them for every defensive handgun I carry I would do it in heart beat they are the most effective sight I have ever used. Put the point of the front triangle on the target and fire. The front sight pops and is easy to acquire, being in my mid fifty range and eyes getting worse I can actually shoot very well with without my glasses and this sighting system.

I'm in my mid fifties as well, and suffer from fuzzy sight syndrome that SB talks about.  However, I think that I would be in the same boat as Ramjet; those sights look fast and easy to me as well.

I've been doing some research of my own toward the red dot sight idea, as I'ld like one for my G20.

I've narrowed it down to the Leupold DeltaPoint Reflex sight and the C-more Systems STS Reflex sight (Small Tactical Sight).

I'm undecided at this point on which one I'll eventually choose.

The DeltaPoint features include:
Magnesium Housing
Aspheric Lens (excellent edge to edge sight picture clarity, along with boosting the usable field of view up to 56% depending on eye relief)
Leupold's DiamondCoat on the lens for extreme antiscratching properties.
Waterproof
Auto-Brightness sensor
Handles up to 3500 Gs of impact (most seem to be only tested up to 1500 Gs for other lesser brands)
Motion Sensor Technology (so it turns on automatically when you need it)
Leupold Full Lifetime Guarantee
Weight = .6 ounces  (that is NOT a misprint, this thing is ultra lightweight with the magnesium housing and all!)
Windage Adjustment Range = 60 moa
Elevation Adjustment Range = 60 moa
Windage and Elevation adjustments can be locked in place after zeroing.
Choice of 7 moa DeltaPoint triangle "dot", or 3.5 moa dot.
Available in matte black only.
Of special note, one must call Leupold (1-800-LEUPOLD) specifically regarding a mount for the G20 and/or G29, as they don't ship the sight with a mount for either of those two platforms.  Beyond that it is not clear if any mount is available for the G20 or G29.
It is required to remove the screws holding this sight to it's base and then flip the sight upside down to replace the battery.
Cost = $400, plus whatever the mount might cost if one is available.

The C-more STS features include:
Aluminum Body
Glass Lens
The lens is hard-coated for maximum scratch resistance (also anti-reflective coated).
Water resistant to 1 meter.
Auto-Brightness setting and Full-On setting.
As for handling recoil forces, they simply say the aircraft alloy housing and electronics are designed to handle the hottest loads from large caliber firearms.
I can't find what they offer for a warranty.  Might have to call them about that at 1-888-265-8266.
Weight = 1.16 ounces with a battery, and 1.09 ounces without a battery.
Windage Adjustment Range = 120" @ 100yds
Elevation Adjustment Range = 180" @ 100yds
Windage and Elevation adjustments can be locked in after zeroing.
Of special note regarding windage and elevation adjustments - there are no "clicks", but rather an infinite adjustment amount within the range of adjustment for perfect zeroing capability.  Also, as with the DeltaPoint, windage and elevation adjustments can be locked in place.
Choice of 3.5 moa or 7 moa dots available.
Available in Black or Desert Tan.
Kind of nice also that the STS incorporates a slide out, O-ring sealed, battery tray, so one doesn't have to dismount the sight to change out the battery.
Cost Online = $400, plus $46 for G20 mount model STSMT-110.















Leupold DeltaPoint - http://www.leupold.com/hunting-shooting/scopes/deltapoint-reflex-sights/deltapoint-reflex-sight-all-mounts/

C-more STS - http://cmore.com/sts.html

These two seem to me to be the best models available.  Your opinion may vary.  Just thought I'ld throw some info out there, since I've already researched it, for curious minds that want to know.

Between those two I'd choose the Leupold for sure. I don't see the slide-out battery tray on the C-more as a benefit; it's not that hard to loosen two screws once a year to change the battery. The Leupold has that auto shut-off feature that is pretty cool.

I'm favoring the Leupold myself.  I believe the glass and the coatings on it will offer the most optically correct/clear/least-reflection sight picture.  I also like that it has fewer access points to its inards from the outside top and sides.  I also suspect it may be more rugged.  Otherwise the overall features of both regarding the red dot itself and what not appear to be fine either way.

Leupold some excellent features on that sight.

Well after reading some reviews on line and considering the price difference I have opted to try the new burris fastfireIII,  I had to order the bomar mount for the STI plus an adapter plate from arrendaro (sp?) If that doesn't work I'll have to get a custom mount made as I am not keen on getting the slide drilled.

Interested to hear if users find accuracy has improved or any issues associated with the sight falling to bits.  I find it hard to believe that these sights can stand the impact shock of sitting on a 10mm slide 

Here is my rig with Burris FF II

Nice. What's the mount? Just curious, what spring and guide are you using on the long slide.

Poly Mount from the Glock Store.

Tungsten Rod with 22 lb spring. From the Glock Store.

Lonewolf comp and barrel and LW Longslide.

Holster by me  cross draw love the comfort and quickness of the cross draw.

Thanks.......I got a LW guide with their flat 24# spring and it's binding badly in my LW long slide.

Actually the bottom of the barrel ?
