At this point, I think you'll be fine........ However, first thing Monday morning (EST), I WOULD CALL the number at the bottom of the page and talk to Matt. Tell him your order number and that you meant to order the new Limited Carry Optics Springs and Followers; and let him check and make sure. If not, he will fix it before your order goes out. He's super helpful and provides great Customer Service. IMO, based on a mag I ordered at the beginning of my ordeal before I knew any better, if the springs and followers your ordered were the 9S version they would show a part number like was on my mag order that came with the 9S follower! My understanding is that "F-S9C" represents the 9S Competition follower. Like I mentioned above, mine arrived in an Ultra Max package; and at this point I'm not sure there's any difference in the Ultra Max and the Limited Carry Optics springs and followers! Same spring length, spring diameter, and number of coils; and the UM and LCO followers are IDENTICAL! This is FACT! And yes, the lack of part numbers, etc. on the packaging is a bit confusing.......

Why do you think this? Mine absolutely came in an Ultra Max package but there was no mention of it on the invoicing...........

Your order is correct! "SPF-CO2011" is the spring and follower for the Carry Optics 2011. "SP-11S" is the 11 coil spring. Correct for the 140 mm mags. "F-9CX" is the "X" 9mm Competition Follower. Again, if you ordered from THIS LINK then you will be good to go! https://mbxextreme.com/index.php?page=Magazines_Optic_2011#!/~/ BTW: Once the 24th round was loaded on my "X" mags, there was ZERO additional give/compression on that top round to allow mag catch lock with the slide forward/closed. I do feel 2-3 WEEKS with the mags loaded to 24 should allow the springs to "settle" and allow insertion/locking on a closed slide resulting in 24+1 if desired.

Same here! IMO, nothing compares to the 1911/2011 fire control group! Unmatched fun factor!

As I started this thread due to the same issues your experiencing; just remember that even though you will get 24 rounds in the mag, there's a good chance it will not engage the mag release lock if the slide is forward/closed! MBX's position is that the mag can be loaded to 24; but does not necessarily mean it can be inserted in a pistol in a 24+1 configuration........... Read carefully:

Glad to help! FYI, the 9S looks like this; and the LCO/Ultra Max looks like this. Has the very small "X" on the left rear. Also note the profile difference.........

As I stated above, I received 3 of the LCO 24 round springs and followers; and this was the packaging they were in. I was able to load 24 rounds out of the package using the UpLula as shown in the FB video......

If you need to get by as cheaply as possible, you can order just the Ultra Max/LCO followers. Just expect to make a small adjustment to the angle of the spring where it attaches to the follower. The 9S followers attach to the top coil just a bit differently....... Or you can order the springs and followers from the link I posted above...... HTS.

Not sure what magazine tube you ordered these for, or if you ordered the entire magazine as these appear to be dedicated for STI Tubes: https://mbxextreme.com/index.php?page=STIFollowers Individual components or complete mags for MBX's Limited Carry Optics (24 round) offering need to be ordered through this link: https://mbxextreme.com/index.php?page=Magazines_Optic_2011#!/~/

ALL: This is straight from MBX: At this point, I think the latest LCO (Ultra Max) springs and followers will allow 24 rounds to be load when using the UpLula. And if shooters want to have the option to have a 24+1 start for a specific Stage, then that/those mags will need to sit for a while loaded with 24 as @zzt and others have recommended. Thanks to everyone that contributed to the thread!

My experience exactly! Since installing have had ZERO upside down bullets!!!

I also think this secondary statement further down on the website listing, clarifies things a bit better........... "FEATURING NEWLY DESIGNED SPRING & FOLLOWER * TO ACHIEVE EASILY 24 ROUNDS" Again, the link: https://mbxextreme.com/index.php?page=Magazines_Optic_2011

@ddc After receiving these new LCO Package spring/follower sets, I have concluded they can immediately be loaded with 24 rounds "IF" one follows the procedure as outlined in this video from their Facebook page: https://www.facebook.com/mbxextreme/videos/753543363059930 However, the mag loaded with 24 CANNOT be inserted far enough into "my" LO pistol to engage the mag release locking mechanism! This is with the SLIDE FORWARD. That top, 24th round, simply won't compress any further once it contacts the slide!!! FWIW, here's the packaging I received today:

Excellent point! Glad to hear I'm not the only one unsure about their statement. Thanks for your feedback @ddc!

I understand; and so far have experienced the same all but impossible to reload the gun with a mag filled with 24 rounds! Guess my goal, whether it proves useful or not, is to start a stage with 24+1 in the pistol; if I feel the stage is optimized for it. So, I'm taking the statement on the MBX website to mean that I can easily reload a mag to 24 rounds using an UpLula; and I can easily reload my pistol, with the slide forward, using one of these mags that's already loaded to 24 rounds: If I'm totally missing the objective of this statement, I would gladly appreciate some insight and understanding from those that are much, much, more experienced with MBX mags than myself!

When I upgraded to the Ultra Max springs/followers, I was under the impression this was the path for 24 reloadable. After sitting for a week with 23 TIGHT rounds I was then able to barely get in 24. No way the top round would give enough, with the slide forward, to engage the mag catch lock. Then after just under 2 weeks loaded with 24, I was seeing some "give" on the top rounds of a couple of those 4 mags; and was able to get those two mags to insert and engage the catch with firm but not over excessive pressure. I'm sure after some more time the springs would take set on all 4 and be fully functional. I'm still hoping to find that combo, like @davsco and @Rich406and get that easy reloadable 24 rounds "right out of the box".......... Hope to test this procedure once I receive the "official" LCO springs and followers.

As of today, I've got 4 of the 2011/141.25 magazines that I previously setup with the "Ultra Max" springs and followers upgrade from BSPS. The mags originally came with the standard "9S" spring/follower combo. Mag tubes and base pads are identical to this latest Limited Carry Optics offering. Received 7 of the LCO followers yesterday, and they appear identical to the Ultra Max followers I already have in length, width, and thickness. And they have the small "X" on the left rear of the follower. Also did an exchange on 3 brand new 9S spring and follower sets for the new "LCO" sets, and should have those tomorrow or Thursday at the latest. Once I get these then I can compare the spring OAL and exact thickness to the Ultra Max sets I'm already using. Unless these new springs have a different (shorter) OAL, or they are smaller in wire diameter, I can't figure how they would stack any differently and therefore allow that advertised " easily reloadable 24 rounds" as I noted above..... Hopefully I know the answer in the next few day........

@ddc IMO, the followers are definitely 3-D printed; but I haven't actually measured some of the several I received to see if there's any thickness differences that could affect operation. I will wait until I receive the actual LCO spring/follower sets for final comments. I plan to compare spring lengths AND spring thicknesses; in hopes of determining if there's actually a component combination that allows the claimed "easily reloadable 24 rounds"..... But noticing this statement on the product listing still has me a bit confused: If these new LCO packages are just the standard 2011 tube with the Ultra Max spring/follower kit, then I already have 4 of these and they ARE NOT "easily reloadable 24 rounds" right out of the package. I have these: https://benstoegerproshop.com/mbx-ultra-max-spring-follower-for-2011-double-stack-1911/ Remaining cautiously optimistic............

@Rich406 I got some of the LCO (Limited Carry Optics) followers in, and they appear to be identical to the Ultra Max followers I already have in 4 mags. ALL my OEM mags including the one ordered straight from MBX had the 9S followers! Early on I thought I would need to use the Ultra Max springs/followers to successfully load 24 and have enough "give" in that top round to have the mag engage the catch positively. So, I decided to get 4 UM springs/followers and put them in my 4 primary mags. At first, 23 would go easy but not 24. Then after being loaded with 23 for a week or so, I was able to get 24. But they would not allow the mag catch to engage. After sitting for almost 2 weeks with 24, I was actually starting to get the mag to insert and engage the catch with firm but not over excessive pressure. I then was able to "finally" talk with MBX CS, and was informed I needed, at minimum, the LCO (link above) followers to get that "easily reloadable 24 rounds". So I ordered enough new LCO followers for ALL my LO mags so there would be no question. Right after that follower order, I was offered to "exchange" 3 9S springs/followers from 3 new, unused mags for 3 of the LCO complete springs/followers. Sent mine out and should have the 3 springs & follower combos by next Wednesday. As of today, it appears the LCO followers I ordered/received are the Ultra Max followers; I won't know "for sure" if the springs are the same until I get those LCO spring & follower combos in mid-next week. I'm still seeking/looking for that "easily reloadable 24 rounds" right out of the package as @davsco shared with me early in this thread!! Have not tried to load 24 with the 9S followers that came OEM in my mags as I, due to my unfamiliarity with MBX, felt certain they were strictly 23 rounds only. Once I get the LCO springs & followers in, I'll be able to directly compare the followers, spring lengths, and spring diameters with the 4 Ultra Max springs that are currently in my mags. I also still have 4 brand new OEM 9S springs & followers from my original mags. Here's a pic of the 9S follower and the Ultra Max follower with the small, hard to see "X" on the left rear of the follower: Thanks for your feedback!

AGREE !!!!

You should definitely be close! Congrats!

@Mandalorian Congratulations on the new LOC! I definitely like your "color scheme"!

Wanted to offer an update: I FINALLY got to talk with a very nice guy from MBX Customer Service, and it seems there is an actual updated "follower" that allows "24 easily reloadable rounds" right out of the package! If anyone wants to take a look at the specific mag and/or followers and/or springs, this is THE LINK: https://mbxextreme.com/index.php?page=Magazines_Optic_2011#!/~/ According to the CSR, they use the same tube and spring as the "Ultra Max" offering; only the follower is different. The follower will be stamped/designated with X in stead of 9S. The exact description in my order: The tubes also have the standard 3 witness holes for 10, 15, and 23 rounds. And as discussed, the upper half of the "24th" round is visible in the 23 round hole. I went ahead and ordered a few of the CO followers and will report back if they are the easy fix........... HTHs!

Ran into an issue recently after installing a new #101-1181-01 Primer Housing Assembly that was replaced under warranty; and wanted to share my experience in case anyone else was having related issues. Seems there was a run of Primer Shuttle Disks that had substandard machining on the U-shaped cutout that receives the primer from the Tube Assembly. Started pulling the handle to begin a stroke, and for some reason the disk was sticking under the tube. Of course when this happened, the toolhead alignment pin would hit the solid part of the disk and stop abruptly! Discovered that raising the handle just a bit would all of a sudden release the disk and allow the entire stroke to be completed. Was constantly happening; but just that bit of raising and lowering the handle would free the disk and allow the load cycle to be completed. Short-stroking DID NOT come into play as the handle was only being pulled/returned enough to start the rotation of the primer disk. My research found a couple of other users had recently incurred the identical situation; and one even had an excellent video showing the issue. If anyone is experiencing a "sticking/hesitation" of the primer disk as it rotates out from under the primer stack tube, remove your tube and take a close look at the receiving notch in your disk; specifically the right half of the cutout:

Couldn't agree more! EE parts ARE some of the best IMO!
