Back to deltapoint for now - durable but flawed.

RTS2 battery contact failure. I have a new RTS2 slide mounted - inside the battery tray slot, the right side battery contact in the back broke off during my first match with the unit. The dot blinked off while shooting and came back on at lowest setting, as if the battery was removed and replaced. When I checked the battery at home - a little plated piece of the contact fell out with the battery tray. Probably not more than 500 rounds through gun with this sight mounted on slide. Called C-More and they issued an RMA # and told me to send it in. Is this the same problem they had with battery contacts with the RTS-1?

Really like the Deltapoint. Update from my earlier post in Sept. I shot the Open Nationals and never had any problem finding the "delta". Brightness was always easily visible in dark house and bright Vegas sun, response to light changes is faster than I can see. Its 2011 now (+5 mo of use) and the battery is still going fine, although will change it before March season opening matches. +++'s notes: the "Delta" is actually pretty neat once you get used to looking at it. I sight the tip of the Delta at 50yds and it gives me a really fine aiming point at long range - as it is closer to the bore (than Cmore and Aimpoint) the difference (aim vs hit) at 7 yds is negligible. As I have a bad habit of "canting" around barricades and walls if close to them - having the Delta slide mounted, it shoots more like iron sights and I don't have a dot on target and then shoot the wall....(dot vs bore u know what I mean). The only drawbacks are: that none of the mounts will fit on a scalloped slide (rear), I got one made by Barry Ruane and it's great. The other seems a design problem by Leupold, the adjustment screws are a torx type head on very small screws - you can't tell when they are moving and where (like with a slot) and they are very easy to strip the heads. Leupold was really good about telling me to send it back after the Nationals and they would check the adj screws and replace if needed - however - it's working so I never sent it back. (I'll talk to Dave Olhasso next time I see him and see what's the current thought on the screws). So far a big thumbs up on the advantages of the Deltapoint. A full 2011 season on my 9 major open slide will tell how tough this rascal is vs all the other micro dots. L-1158

Barry Ruane mounted the Deltapoint (on the slide) for me with a custom mount (on a previously milled flat slide surface none of the stock mounts will work) on Thursday (26 Aug) and I shot Area 8 with it on Sat (28 Aug) and triangle was easily visible. Always used an Aimpoint Comp SM (7min) dot so switch to triangle was very distracting - use it a while before shooting a big match!! The triangle is "busy" with all the points and shape that you don't see with a dot. No verdict yet on if it will hold up to constant beating from major 9mm even with soft shooting Jim Hand comp (EGW). No battery change yet.

Done more testing with that comp design George mentioned. Seems we may have stumbled into a perfect storm situation where the gun works really really well but since we changed so many things in the comp, top end, 9mm etc, I'm not sure which was/were most important. Previous post by Mike was a bit premature, first shots thru comp etc., the load was a tad light with a new lot of HS-6 and speed was about 1270 (124 gr). However, good news is that goosing it up a bit to 1350 (10 shot av, Oehler Chrono) didn't change a thing, the comp/top end system is dramatically more effective and shootable (very flat, soft shooting, much reduced torque) vs my super (clone to the new 9 maj) with another well designed and very efficient 4 chamber 6 port comp - not by EGW. George agreed to put one of the new comps only on my remaining backup super to see what effect it contributes. Should have results before x-mas as I'm headed to the caribbean for some diving. JMH
