Rim Lock can be a problem in these little lite pistols. The HP is shorter than FML So their is room for rounds to move around in mag . The top round can jump over rim of round below during recoil . Well that is a real show stopper .
You can
1 Only shoot ball ammo
2 Take chance never happen many fokes do.
3 Loadchamber with HP and top round of mag with HP rest ball Will not rimlock this way .
4 Install rim lock kit. and practice with HP or the Winchester flat nose . This same length as a HP and will also rim lock.
I have 2 mags set for HP and 2 for ball.
Seecamp has a similer set up in his 32's That why he says only shoot ... The 32 auto sepending on who makeing varies widely in over all length were talking 1000's here but is a diference.
380 not bothered with this Don't let it keep from buying a 32 Kel Tec it ain't a big deal. I carried mine #3 above till I got all the mags I wanted then I converted a couple.
Takes couple min to install .
