Being a drop in kit, I imagine reliability will vary based on what it's installed in. Springfield's being on the supported list for Clark's kit, You'll probably have no problems. I put one in my Sig which is Cerakote covered stainless and used the 24lb spring, I've not had a FTF issue in over 200 rounds. That's not much due to the cost of Buffalo Bore ammo but I'm thoroughly satisfied. I had not seen the Recover rail, that's a great option for older or railless models. Compared to +P 44 mag Buffalo Bore at 1600 or so ft/lbs, the 957 ft/lbs of the 255 gr hard cast .460 seems like the "energy of 44 mag" claim pales but it is squarely within standard 44 mag ballistics. 8-10 rounds of that kind of power in a single action auto with a light is a good way to go IMO. Good luck with it.
