This POLYMAG has been initially sanded and function fired using our frame.
You may have to fit the POLYMAG to your frame's magazine well by sanding
with some 240 wet or dry paper. Some has been enclosed for your use, any
flat surface will work.

We have found that magazine wells vary quite a bit among frame manufacturers
and that the POLYMAG (or any magazine) must be able to drop free of the
frame without any assistance.
We would rather ship a POLYMAG that may require some fitting rather than
produce one so loose as to fit all frames.
