I got a couple of long and short pads in today.
Just spent some time at the workbench playing with different combinations of the mags/pads.
This is all with the +10% spring and untrimmed followers.
Stock SP01 mags are supposed to hold 18, but they actually hold 19.
With the new short mag pad, they hold 21, so +2.
With the long pad, 23. (Too long for Limited, I dont have a gauge, but they were well over 140mm)
MecGar AFC mags hold 19...the short pad adds no capacity.*
The long pad adds 2.
*note the MecGar AFC 19 rnd mag has a plastic +2 pad on it already.
MecGar non afc 16 round mags:
Short pad adds 2, so 18 rounds.
Long pad adds 4, so 20 rounds.
The grooves in the mag pads need to be scraped out a bit.
I assume its the coloring process, but the groove was really tight.
I scraped them out and still had to use emery cloth on the MecGar mags to get them to fit without a mallet.
The short pad on the stock SP01 mag is promising. 21+1 will be fun when I play Limited Minor.
I wont have the chance to try this combo on the range until next week.
So, how much can I grind off the followers before it causes problems?
