I have just purchased my first pre-ban from a show today for 150.00bucks. It is a drop-free 15 rounder. when I got home I went to load to full capacity and cycle it with my thumb one by one when suddenly the round did not come up!I then tried cycling it through the G31 and it happened again!I proceeded to load it up more time and noticed there was a lot of play up and down when it was fully loaded enough to easily get a 16th round in the mag!!!!!!My questions I need Answers for are.Do I or Can I change my follower to one of my .357sig/10rd followers"IS THIS LEGAL TO DO!"Or is the .40 follower just fine?Are the springs totally shot!!!!!!
!?Can I even use this mag in a G31?Once again the mag that was purchased is a drop free 15round pre-banG22.Any Answers would be a Big help guys THANX!!!!!!!!!!!!
OK to use unless your state has a specific law.
Sounds like you need a new spring.
Try with a new spring and see if you also need a new follower.
Test during actual firing.
Cycling by hand may not give you the same results.

Use the latest design .40cal follower (#5) and ISMI springs and you shouldn't have any problems.
I agree with G33, the spring seems to be in a need of replacement.
( btw ) I see you must be from Boca.

Will my standard .357sig/10round follower work just as fine or should I purchase the #5 follower!I have just ordered the IMSI springs.Yes I am from Boca Raton! THREE-FIVE-SEVEN;f ;f
I think the 10-round follower does not provide for the off-set of the cases.
First - always use Wolff springs (www.gunsprings.com)
The only Glock failures I've had have been mag spring related. For $7, you can cure the problem. Replace springs every 3 years in mags that are carried daily.
Second, DO NOT interchange post ban and pre ban followers - not for legal reasons, but functional ones. Mixed reports on whether it is a good idea. Call Glock on that one.
Last - You got ripped off. Hi caps are available all over for $80. Do more homework, you could have had two $10 more.

Mag problem solved!I returned it to its rightful owner!Why do I need 15rds.?I don't 10rds. is fine for me but maybe i'll get another preban in the future for a better deal!:)
Hey, slow down on the exclamation points (!), pal. It's giving us all a headache. Please type normally and we'll answer...
Do not put a 10rnd 357 follower in a pre ban mag, not for legal reasons, but for functionality. Glockmeister has in stock the standard capacity 357 followers, or you could get the #5 .40 followers, they are the same, just stamped differently.
I would recommened a new mag spring as well.
I had the same problem. New mag spring - problem solved.
