1911 Mag Base Pads

[slicknick]

Recently bought a 1911 with a bunch of GI-style 7rnd mags. My meaty mitts have been getting pinched during mag changes with these mags but are fine with mags with base pads (bumper pads?) installed. Anyone have a source for them? Trusted brands? My google-fu is a bit weak.

Brownells has a bunch of promo's on atm, free shipping, discounts. They've got the best variety.

4gt has the Packmeyer's.
