P7 pistols are "restricted". I went through this with CFC when I moved to Canada, was told the P7 was "prohibited", and sold my PSP. Later, I was told that it was in fact "restricted", and I own a registered P7M8 now. The measurement is close, but the barrel is "restricted" length. Measure it by placing a rod down the barrel on the pistol with the breech closed, which is how Canadian firearms law requires the measurement to be done. Do not measure by taking off the slide and measuring the barrel by itself.
