Testing the Canik TP9 magazines in the Taurus PT-111 G2

A quick test run of the Cank55 TP9 18 round magazines in the Taurus PT-111 Millennium G2 , I shot 13 rounds out of the Taurus magazine, then shot 18 rounds using the Canik TP9 magazine, then fired 18 more rounds using the Canik magazine rapid fire.I used Federal Aluminum 115 grain with no failures, but the slide does not lock back using the Canik mags.
