TF just released a solid brass Canik +0. The golden glow of natural brass looks awesome, and they weigh enough to dampen recoil. You can’t use them for IDPA competition (too heavy), but at 2.7 ounces, they’re legal within the USPSA Production rules. You can get some here: http://taylorfreelancestore.com/canik-0-basepad-brass/
We just got confirmation that our VR80 +3 magazine extension also works on MK1919 magazines as seen in the pictures. Thanks to everyone who sent in a picture verifying this fact to us!
