MAXIMUM FIREPOWER! Taylor Freelance has updated 170mm floorplate offers up to +12. Optimized for 9mm in this revision, giving 9mm "Open gun" drivers a chance to load TWENTY NINE and one in most cases. Taylor Freelance also re-profiled the interior to better accommodate the new "chisel-point" followers. This 170mm "+8" was their first mag extension, built for USPSA's "Open Division" in the 1990s. ("Open" is the firearm equivalent of top-fuel drag racing.) This latest version provides as much as +12 rounds of 9mm, depending on the particulars of your magazine/follower combination. Ships with a custom-made Wolff spring.
