I have done a search and this has not been discussed. I also cross-posted with another forum asking for help.
My eyes are not what they used to be. I have difficulty with the rear adjustable sights lining with the front. I would like to mount a Trijicon RMR to my RO. I have called Springfield about this concern. They recommended to get a mount/adaptor for the LPA cut. I do not know what LPA stands for.....And when I do get the mount, I will then contact Springfield to arrange for a custom install. I also have contacted Trijicon for their input. I still have not received any response since I just sent the message. Would anybody have a recommended mount/adaptor for the RO? Your inputs will be greatly appreciated. Thanks. |

If you google for "LPA rear sight" you'll see all the info on it...it's a type of rear sight, with a more or less unique rear sight cut. Springfield is saying to get some sort of mount that will fit in that cut (Which is already in your slide, as you have an LPA rear sight), and they'll mount it.
There's a bunch of ways to put an RDS on a 1911 - IMO, the proper and correct way is to have the slide milled for it, to mount it down low with the ability to co-witness taller iron sights as a backup. Of course that may not fit your needs or wants...especially if you don't want to modify the slide. RMRs that sit in mounts that mount via existing slide cuts in the slide tend to sit a bit high over the bore. Having a mount milled into the slide allows the sight to sink into the slide more, providing a better sight picture...and depending on how it's done, will allow you to mount taller suppressor sights on the slide and keep both irons as well as the optic. If you don't care about iron sights at all and if the height over bore issue doesn't matter, then mounting the adapter plate directly into the rear sight cuts might be a better option for you. It'll certainly be less expensive, either way. Trijicon doesn't seem to make a (Factory) mount that fits in the LPA rear sight cut...they make them for Beretta cuts, Novak cuts, Sigs, etc...but not for the rear sight cut on a Springfield RO. They may have to custom make you one... |

So now you have me thinking, and it raises a question. Is a RMR viable for a home defense gun? Is it viable for a carry gun? I haven't really looked hard at these, but I'm possibly interested.
I just took a look at a pic I took, and it looks like it would be a very close fit w/my Milt Sparks SSII. Maybe if it was machined into the slide to be flush w/the back of the slide, it could work. |

Since the time I have posted tbhis in a few days, I have done further research. Evidently, JP Enterprises have manufacured for LPA specific. The merchant who deals with LPA mounts is Evolution Gun Works selling the LPAs for JPoint and DeltaPoint. And there are specific plates and shims that will adapt for Burris and Docter. Vortex Razor also have an LPA cut mount.
Doing more research. But the most important one is the LPA sight cut mount being available. I am now trying to decide with Red Dot route would I take......read $$$$$. |

There's a thread on another pistol forum (hint) where several shooters, including DocGKR (Doc Roberts, ballistics guy, and former frequenter of these forums until he was run off by rampant asshattery) opine that it's not only faster, but easier to make those low-percentage shots with a lot more frequency and a lot faster than with irons alone. They suggest active sights vs passive (so the RMR with the LED in it, not the one with just tritium) as they are much brighter and easier to adjust and see, and won't wash out in varying light conditions as easily. There's varying discussions as to the merits of the Deltapoint vs DR vs RMR...depending on where sight adjustments are, battery access, etc. There is a learning curve, but it's not steep...and once it's figured out it's pretty much shooting on "easy" mode from there on out. Concealment wise...there's very very little difference. I've been off-and-on considering having a Glock milled for an RDS of some kind...what I'd LOVE to do is get one of the Unity A.T.O.M. slides but alas; I don't have a Gen3 Glock anywhere to drop it onto. Fortunately Glocks aren't really collectable, so it won't exactly be ruining anything by having one worked over for an RDS

They're probably durable enough, but I don't like dot sights to be reciprocating. |
