Tandemkross wingman bumper for ruger lcp ii in .22lp installation trick - TANDEMKROSS Wingman Bumper Ruger LCP II in .22LP +4 Rounds Magazine Extension

This was an excellent addition to my standard 10-round magazines, but here is the trick to make the installation go easier. Remove the pen tube from a Bic pen and insert it into the small hole through the new magazine spring. This keeps spring from bowing sideways as you compress the spring within the magazine well, as you bring the two halves of the Tandemkross wingman bumper together so that you can complete the screw tightening operation and complete the installation without the spring from going BOINK!
