New G27 with #7151 mag base

[gen1]

Mga bossing !

I have a new G27 bought at he last gunshow. It came with a #7151 mag base which should make it a 9+2 mag.

However I can only insert up to 9 rds into the mag. Any tips on how I could insert the extra 2 rds?

Thanks !

Load it up to the max it can hold meanwhile. The spring will settle some after a couple of weeks so you can add another round. Then another later on.

Good Day.
I think the 7151 base pad (Glock Stock) can only add up 1 more round in cal .40S&W. It may give you a plus 2 but only if you use it for the 9mm ammo.
And as Sir Django had said, the spring will settle down after some time.
Happy safe shooting!
