Trimming Mag Lips

[Smitty79]

I’m shooting carry optics with my Shadow. All of my mags just fail the length test with TT or CZC base pads.  I need to take about 0.5 mm off of the feed lips to pass the gage.  How do I do this?  File? Dremel?

I would NOT take any lenght off the feed lips. The geometry of those is too important. Take the length off the basepad or find a better set up.

File the base pads.

yep, knock the base pad down, starting with the rear edge until it fits.

 

another trick is if you can press upward on the basepad and it moves an amount that would have you pass is to bend the lips on the bag that the basepad slides onto "up" so that they take up this free play. i've shortened mags just enough this way and then you don't have to do any external changes. i would not consider it a permanent solution though.

 

at least you checked yours! for fun i took my mag gauge to our local match once. it was shocking how many Lim and CO mags people were using failed.
