Here’s an easy way to turn a TF +3 for a SIG 226 into a +5. The SIG “20-round” magazine uses the same mag tube as the 15-round (standard) magazine, but with a shorter follower and a hollow plastic base pad. A customer called this morning, wanting a better/stronger basepad that would give him 20 rounds. Switching the followers and adding one of our machined-aluminum +3 extensions got him a SECURE 20 rounds. You can do much the same thing by trimming the bottom of the stock follower to match the SIG “20 round” version (shown).
