Hey guys,
I have 3 SPS 140mm, and my gunsmith cut them to fix the box here in Brazil we use the BOX in Standard Division. So i buy this mags in Worl Shoot last year in Ecuador, they have this new follower, very good by the way, and after cut this mags, i can load 19 rounds, when i get them they load 21 rounds, i also have a sti 140mm mag, but after cut they load only 18 rounds.
My suggestion, buy SPS mags for 45 ACP and ask to your gunsmith to work on them and transform to .40S&W, they will load easely 21 rounds with 14mm leght, and if u cut to fix the box, it will load 19 rounds.
Bye
