take into consideration this is 950fps from a 4" barrel. out of a 16" barrel they are almost 1250fps32 grains at under a 1000fps is likely too light and slow to reliably cycle in a pistol with a reciprocating slide. My glock with advantage arms kit will only cycle reliably with 40 grain (CCI mini-mags, blazer, AR Tactical, and standard). 36 grain mini-mags do not feed reliably.
My Ruger MKI eats everything but it's not the entire slide that reciprocates
