Thomas:
Thanks for the info on the NATO rounds.... I never ran into that before....
I'd prefer sticking with non-Plus P ammunition, as I stated earlier, but if the manufacturer hasn't warned you, it shouldn't be a real problem on an "occasional" basis.
(And the usual "rotate your carry ammo" shouldn't bother a thing.)
(Just to be sure, "made after 2000" might be a good test, too
.)
Regards,
