Kimber Magazine with the floor plate removed. Note the spacer attached to the spring.
The spacer is removed from the spring allowing 15 rounds to be
Loaded. You may want to stretch the spring a little to makeup
For the tension lost due to spacer removal.
Re-assemble the magazine without the spacer. Note the spacer
Was also a lock for the floor plate but as you have noticed the
Floor plate is a tight fit and will not slip off easily.
