MAXIMUM FIREPOWER! The TF updated 170mm floorplate offers up to +12. It is optimized for 9mm in this revision, giving 9mm "Open gun" drivers a chance to load TWENTY NINE and one in most cases.
TF also re-profiled the interior to better accommodate the new "chisel-point" followers.
This 170mm "+8" was the first mag extension, built by TF 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.
Got a .40? TF recommends their new .40-specific 170mm basepad. The 9mm version will work with the .40, but is finicky about bullet profile. Small changes make a big difference!
Ships with a custom-made Wolff spring.
