Why not just email them or call and ask? The email address and phone number are right on the website.

It would have to be safe for any factory loaded .45ACP ammunition, or 21,000psi.

UM, maybe not.
Other conversion cylinders are not rated for "any" factory load for the .45 Colt, and clearly state they are only good for commercial factory "Cowboy Action Shooting" loads, as well as black powder cartridge loads (which is really what they are made to use). Typically these CAS loads when done with smokeless powder for the .45 Colt are at the highest at below 14,000 CUP and many loads are below 10,000 CUP as are the Triple Seven loads, and the heaviest of all Pyrodex loads is 13,500 CUP..., , while non-cowboy factory loads and reloads for the .45 Colt can exceed 14,000 CUP and the .45 ACP often are at 16,000 CUP or higher..., AND the .45 ACP loads normally use a jacketed bullet while CAS loads are always lead. Something like a 230 grain JHP .45 ACP Cor-Bon round might turn such a conversion cylinder into a frag grenade.

Not the same thing. This is obviously offered so that cheap factory .45 hardball can be used in the sixgun. They would be stupid beyond measure to offer a .45ACP cylinder that could not handle standard pressure loads.
Factory loads should never exceed standard pressures. Unless it clearly states so right on the box. There should never be any confusion over what loads are standard pressure and what loads are not.
NEVER assume that any load marketed by Buffalo Bore is over standard pressures.
I don't have a Pietta 1858 Remington. I do have two Ruger old army stainless
with Kirst konverters, one with 45 ACP and one with 45 LC. I shoot Winchester
45 ACP 230gr. JHP....muzzle velocity 880 fps. about 1,600 rounds out of the ROA. The 45 LC cylinder I am shooting TUG HILL cartridge,inc...manufacturer
of factory ammunition. 250gr. Hornady xtp (JHP) muzzle velocity 1,000 fps.
1,150 rounds out of that ROA. Both guns still have excellent lock up.
Just my two cents....it may not work in your ROA. Call Jay Strite at Kirst Konverter ( 254-248-0663 ) he is Kirst gun smith. Tell him the gun you have
and the ammo you would like to shoot in it, he is great to talk to.
