Thanks for the mag link Walkalong!
Nice Kimber.
Didn't you have an EMP in 9mm?

My Redding sizer sizes the case mouth just as well as my Lee sizer, but the tapered insert in the Lee sizer doesn't leave an unsightly bulge near the case head.PS-Between my Lee sizer and the Hornady the Lee sizes cases tighter so I use it.

Yes, great gun, resides with my younger child now.

Since my return to reloading has lead to this I’ll try to slip in one more question before desisting.
SPRINGFIELD ARMORY RANGE OFFICER ELITE Target 9MM Trigger;
I was reading some specs on the Range Officer Elite Target and it mentioned having a Gen 2 trigger. Would any of you happen to know what that entails?
Thanks to you all for your patience.

I just found the following quote in an article about the Range Officer Elite Target. "The RO Elites come with Springfield’s new Gen 2 trigger which broke at a crisp 4.5lbs with a short reset. The trigger is a non-adjustable Pre-series 80 type."

"The Gen 2 trigger was outstanding with its smooth take-up and clean break ... With the short reset, follow up shots were quick and precise ... The Gen 2 trigger is one of the best that I have felt on a production gun"

My guess is "Gen 2 trigger" is marketing for they pay more attention to the trigger/sear/hammer engagements as well as all the surfaces they ride on/against. More like a custom maker would. If it is an actual design change I would surely want to know what, where, and why.

Oh just great! I have been thinking about and talking about buying a new 1911 for well over a year now. With all this talk I have that itch again and I do like Springfield, even more now with all this good talk.

For some reason I feel this might be my fault 
But as mentioned before a full size all steel 9mm 1911 is just a downright fun..
Please post us a pic when you get it and let us know how it wokrs out.
hopefully i didn't steer you wrong.

One thing’s for sure you got me pointed in the right direction and with doing some skull sessions the short list I had, very short, went in the trash. The new list had only four pieces on it and they were all RO models. The models in the new list were in my interest priority, PI9129E, PI9122LP, PI9129LP, PI9130L. As fortune would have it my first stop landed on an Elite Target being available.
I thank you and everyone that had an interest in my decision and all the input. I’ll sure keep you all posted when it arrives and how we get along. I'm feeling very good about this selection.
Here’s a photo of the model I chose for those unfamiliar with the Springfield Range Officer models.

Looks like the left grip has a little relief for access to the mag button, I like the one in the mag pull grips, not hard to get to in the first place but the relief cut makes it a little easier.

To bad that model is not approved in CA, other wise I my be tempted to buy a second one to have around as a spare
(Stupid CA approved handgun list, any thing new must microstamp which of course is worthless.....)

My first load using RMR's 9mm 124 gr JHP MPR -
Powder: W231 4.0 gr
Primer: CCI 500
OAL: 1.050
FA: Glock 43
Please excuse the marksmanship. This was off a sand bag at 8 meters but I though the "gathering", can't call it a group, was moving in the right direction.
Now, reading another thread concerning this bullet, see right side of following photo, and testing loads with W231;
"Perhaps you can load 2.4, 2.6. 2.8 3.0 gr test rounds to see how they cycle the slide and which load produces best accuracy."
I would like to try this but wonder if the OAL length of 1.050 would develop enough pressure to prevent a projectile on the low end of the mentioned powder weights to become lodged in the barrel or should I instead use the OAL of 1.040?
Thanks for your patience.

I suggested those test charges to START for initial powder work up as member RMH posted very short working OAL of 1.030" based on Hodgdon's published load data of Start/Max of 2.8 to 3.3 gr at 1.069" - https://www.thehighroad.org/index.php?threads/rmr-124-mpr-jhp-oal.825436/#post-10626094
With small internal volume 9mm, small changes can significantly affect chamber pressure. Since RMR 124 gr MPR bullet length is slightly shorter than typical 124 gr JHP, resulting bullet seating depth will be slightly shallower at same OAL. When using much shorter OAL than published, I usually reduce start/max charges by .2-.3 gr and that's how I arrived at 2.4 to 3.0 gr test charges.
Of course, if initial test charges work fine, you can always go up higher.
I tested RMR 124 gr JHP (bullet on the left in above picture) loaded to longer 1.125" OAL at 3.2 gr and bullet definitely left the barrel. Here's chrono data from 16" PSA carbine.
124 gr RMR JHP 3.2 gr W231/HP-38 @ 1.125": 820-838-784-807-860 fps (59 F - PSA carbine)

Thanks very much bds. What got me started was a plunk test I did with the RMR 124 gr MPR in the G43 and finding that an OAL approx. > 1.055 I felt was dragging.

Since you already tested 4.0 gr W231 at 1.050", how about working down and testing 3.8, 3.6, 3.4 and 3.2 gr?
If the slide cycles reliably and produce accuracy at 3.2 gr, you can further test 3.0, 2.8 and 2.6 gr (or until slide no longer cycles reliably) and use the powder charge that produces best accuracy.
This is powder "work down" instead of "work up" that many bullseye match shooters do with Alliant Bullseye powder that downloads well.

Hey, I stay wrapped around the axle, don't be too hard on yourself.
Low charge weight/velocity/cycling test with W-231. (.45 ACP, not 9MM, but a good example)

Since the Lee die set I am using with the one RN type bullet plug I decided to take them up on their offer of making a bullet plug for you if you send the bullet in question for the reasonable price of $14 which includes the shipping. I decided I wanted a plug specifically for RMR's 124 gr. jacketed TCFP to use when setting those bullets.

The Springfield RO arrived and while disassembling and cleaning thought I would plunk test the OAL I have been using for the Glock 43 with RMR's 124 gr. TCFP and their 124 gr. JHP MPR to check the compatibility of the OAL for both FA. Really looking forward to cranking out rounds for the RO now.

Looking good!
For determining max OAL using the barrel, consider measuring several resized cases and using the longest case as shorter cases will allow more bullet nose to stick above the case mouth.
But if your working OAL is shorter than max OAL, resized case length variance won't matter that much as shorter resized case rounds will "headspace" off extractor.

Can't wait to see how you like the new RO, and for that matter the Ruger you won.
That worked out well a new one for you and the wife.
