I have been trying to find pre ban mags to fit my Glock32 .357sig. Not sure if there are any, so any help is appreciated.
You can change the follower in a pre-ban mag.No not really. You could use a preban 23 mag and change the follower however I am not sure if that is allowed or not...otherwise u can just get a Glock 23 40 barrel and use a 40 preban mag...that is what I did with My G32...I just had to make sure my permit reflected both calibers
Would the follower need to be changed out seeing that the .357sig is a necked down .40? I know I have asked many questions here, but want to make sure I do it correctly.Yes you can put a 357 follower in the 40 magazine...check out Lone Wolf Distributers for the follower...I was unsure if NY law would allow it but looks like it will
