I was cleaning one of my accessory boxes this morning. I have the following for sale:
Pearce Mag extensions PG-26. These are magazine extensions for Glock sub-compacts 26, 27, 33, or 39. They are basically just a pinky rest. They don't add any rounds. They sell online for $7-$10 each. I have four of them. $20


Pearce Mag extensions PG-19. These are magazine extensions for Glock compact 19, 23, 32, 38 (will also fit corresponding full-sized Glocks, but I have no idea why one would add extensions to a full-size). Again, these are basically pinky rests. They don't add any rounds. They sell online for $7-$10 each. I have two of them. $10

Pearce Mag extensions PG-39. These are magazine extensions for Glock sub-compacts. They ADD rounds to the following magaines: 26 +3, 27 or 33 +2, 39 +1. They sell online for $7-$10 each. I have two of them. $12


Pro Mag PM050 +2 Floor Plates. The package states they will add +2 to Glock 9mm & .40. I would assume it would do the same for .357sig also. They will fit 17, 19, 26, 22, 23, 27, 31, 32, 33. They'll also fit .45 GAP models 37, 38, 39 adding only 1 round. These sell online for $10/pair. I have one pair. $6 (must be a misprint on package, it says "2 pair". There is no way they can fit 2 pair in this blister pack.


I will be at the steel shoot in Hutchinson Saturday. I could also meet nearly any day at the Burnsville Pistol Range.
