Pearce Plus Extension for GLOCK 10mm / 45 ACP Not for G30 10 Round Magazines
Detailed Description
For use on Glock 20, 21, 29, 30 (9 round magazines), 40 and 41 Full Metal Lined Glock magazines. Increases the capacity of the magazine by 2 rounds. Incorporates fourth generation texture pattern.
Bought about 10 of these for my G41. Use Wolff extra power springs for good reliability.
Two or 3 of the 10 base pads have swollen to the point of easily coming off by hand while loaded. Recommend the Glockmeister brand ones. Have 3 and they are much more robust. These are decent but not high quality.
