I recently came across mention of the trigger reset on the P99. I had not realized that after firing, the trigger resets after moving forward about 1/8th inch. I tried rapid fire by releasing the trigger only slightly and then squeezing again. I was able to fire VERY rapidly (3-4 times /second). Is this common knowledge? I've only seen it mentioned once in all the info I've read on the P99. Is the Walther unique in this regard?
