My 1982 BHP had the locking cam break a few years ago. Cylinder and Slide charged $459.24 to repair it. I probably ran too many +P and NATO rounds in it.I understand that ammo marked as 9x19 NATO is loaded to a higher pressure than ammo marked 9 mm Luger.
Would 9x19 NATO be OK to use in older (pre Mk III) Hi Power pistols?
I also converted a BHP to .41AE but could never get it to function reliably. Finally gave up and put it back to 9mm. I still have the conversion kit by Action Arms; barrel, recoil spring and two mags.I also built one of the first Brownings in .41 AE, in fact I used the prototype barrel Bob Shutz of Olympinc Arms sold me. That round moved the slide so fast you could barely see it move! Tom Givens wrote it up for Combat Handguns as "A Higher Power"...I think that was mid 80s sometime. Riposte
