Works with modification - Strike Industries Canik TP9 w/ 9mm 5 Round Extended Magazine Plate

I've had these extenders for several months now and after reading other reviews i figured I'd share my experience. First off, the design on these are horrible and have to be heavily modified in order to work. I actually took them to a griding wheel and shaved off the rear lip completely in order to work with the mag well extender on my mete sft, sfx, rival, and combat elite executive. The second thing is that the included spring is useless. You have to use your OEM spring and this will allow you to get +5 out of it. I wish I could attach pictures of how I shaved it down and it does work and look great now. Would I recommend these, yes, but only if you're willing to shave it down completely to fit. I got 3 of them and the first one took me the longest because I kept checking the fitment but by the third, it probably took 5 minutes to shave down. Don't expect to do this with a manual file though, it will take you forever.
I have since bought more of these and am quite happy with them.
