Answers from CMP, Jim Henderson, on Sight Rib and Internal Recoil Reduction Questions

All, I had some questions on EIC service pistol under the new 2023 4.1 rules which I sent to CMP yesterday 26JAN2023 asking, 

"1. Is a Bomar sight rib, with tuner, now acceptable to CMP on a service pistol for EIC? Saw something about a Rock River combo rib on the Bullseye-L Forum that got me wondering as it was suggested it was.  Seems like adding a rib of any kind would be an external modification and thus prohibited.  

2. Is a Sprinco internal spring recoil reduction system that does not poke through the recoil spring plug and out in front of the dust cover and uses the issue solid recoil spring plug, now prohibited by CMP on a service pistol for EIC?  It was considered internal and has been acceptable for years."  


I got a quick reply from Jim Henderson via Christina Roguski earlier this morning and it is:

>> As far as the recoil reduction system you asked about, on page 36 of

>> If you have any other questions, please email me.

>> Thanks again and I look forward to seeing you on the firing line.
