cjmill87 Posted April 28, 2020 Share Posted April 28, 2020 The 508T actually weighs slightly more than the 407 or 507 (2 oz compared to 1.5 oz), the main benefit to the 508T is supposed to be the more durable titanium housing (compared to the aluminum housing of the 407/507). In the Sage Dynamics video above, he drops the pistol on the optic from shoulder height 4 times over 2,000 rounds and the zero is still the same. It does look a bit worse for wear cosmetically though Link to comment Share on other sites More sharing options...

Then I bought a used X5 slide and put the Holosun on it. I'll run the holosun in practice to keep rounds off of the SRO and only use it at major matches only. Well, apparently I'll also use it when the Holosun is down too lol. At some point I'll just get a second SRO. But I'm hopeful this 407 will hold up because it's a decent sight and can keep the cost of entry down if you're on a budget. I'd like to be able to recommend it to people but I'd like to know it'll hold up first. This sounds like a great idea for someone on a budget who still wants to be competitive. I'm not looking to seriously compete yet, so I'd rather start with the cheaper option and upgrade if I decide to move out of limited Link to comment Share on other sites More sharing options...

The T does get titanium and has a flat top, and I think it has a better warranty. And the reticle options are different between the 407's and 50X's. For me, the $200 I paid for the 407 was worth a shot. Hopefully it works out. If not I'll just sell it for something else. Link to comment Share on other sites More sharing options...

I have a fastfire, Romeo 1, and vortex viper and the DPP is the best of those because of the large window and bright dot. I picked mine up for $300 used. Hope that is helpful. I ended up finding a DPP used locally for a decent price. I'm hopeful it will meet my needs. I'm very excited for the gun to get here so I can try it out!

alien_pickles Posted April 30, 2020 Author Share Posted April 30, 2020 I'm hearing the adapter plates can cause issues with the sights maintaining zero, since it raises them. Anyone know anything about this? Is there an actual disadvantage to using an adapter plate other than having to buy another piece? Link to comment Share on other sites More sharing options...

Anyone know anything about this? Is there an actual disadvantage to using an adapter plate other than having to buy another piece? My pistols use adapter plates to mount RDSs; I don’t think they are inherently a problem. I watch out for plates that raise the optic “too” high, depend solely on screws to resist horizontal movement, or are poorly machined. They can cause a shift in zero if they slip on the slide or allow the optic to slip on the plate. I doubt that raising a sight would cause trouble holding zero.

I don't have it yet. Would that mean it would need the mounting plate for a DPP or Romeo1Pro then? If it is a Legion NO you don't need a plate for either of those 2 as that's what was designed to go on them. If your lucky and it's got the extra set of holes then you would be able to fit any other RDS that uses the RMR hole pattern. Link to comment Share on other sites More sharing options...

alien_pickles Posted May 6, 2020 Author Share Posted May 6, 2020 I can't speak to when this was manufactured since I purchased it second-hand, but it arrived today and has all these holes. So... I'm guessing they are now compatible with more stuff? Link to comment Share on other sites More sharing options...
OhioLefty Posted May 7, 2020 Share Posted May 7, 2020 Looks like you got the newer revised mounting holes. Just FYI, if you got the original case with your X5, the manufacture date is in small print on a sticker at one end of the case. Link to comment Share on other sites More sharing options...
BobRockefeller Posted May 7, 2020 Share Posted May 7, 2020 How is the RMR secured to the slide? Just by it's screws? When the DPP is in the slot, it's held down by screws, but also bears against the front and back of the slot so that the screws take less impact.

mgkrs Posted May 7, 2020 Share Posted May 7, 2020 Surprised they added holes for the RMR and yet still didn't for their own Romeo 3 optics. Link to comment Share on other sites More sharing options...

BigAm Posted May 13, 2020 Share Posted May 13, 2020 Have friend trying to mount and SRO to the slide directly. Holes line up...but the thread pitch on the screws seems to be different. Does anyone know what the thread pitch of the slide holes are? I'm not there to diagnose in person currently. Link to comment Share on other sites More sharing options...

mxj23 Posted May 14, 2020 Share Posted May 14, 2020 I just mounted this directly to slide after reading this thread and realizing my slide had the holes for rmr, previously was using springer precision plate, only about 75 rounds through it since changing but didn't notice any ejection issues Link to comment Share on other sites More sharing options...
Boomstick303 Posted May 14, 2020 Share Posted May 14, 2020 (edited) I find the discussion of the optic interfering with the ejection port on the X5 Legion interesting. When I first purchased some of the first Springer Precision adapter plates for my SRO, the adapter plate placed the optic even or maybe even ever so slightly over the back edge of the ejection port. From what I observed possibly the most forward position of an optic on that gun, due to the way the SRO is built. I never had any ejection problems. I never obtained video of the ejection port as the gun fired to see if there was contact, but there were no scratches on the Optic case that would indicate casing were hitting the optic upon ejection. Is this possibly due to using different recoil springs which would in turn effect the direction the casings were ejecting? Maybe cause the plate increased the distance between the port and the optic? Note on the picture, the scratches on the optic came from me rubbing the optic on a concrete bench rest when holstered.

If the optic is not snug against the front and back of the cutout I would have some concerns if only the screws were taking the brunt of the blow as the slide actuates.
