I am also looking for that "crutch" to tame the recoil and flip. lol I picked up a Hellcat Pro as a slight downsize to my G19 Gen5 with tungsten guide rod.
So far all I have found is the DPM Recoil Reduction System. It looks interesting but might be a bit overkill for what I am looking for...
I just mounted a Holosun HS507k to my Hellcat Pro OSP 9mm using the CHPWS mounting plate and am looking for recommendations for iron sight upgrades that would give me a lower 1/5th or lower 1/3rd co-witness. Any assistance would be greatly appreciated. Thanks
