The 17L was discontinued for a time but there were some produced not too long ago. The older models had ports on the muzzle(1st generation) and were prone to crack at these ports, just a word to the wise. The main difference between the 34 and the 17L is barrel/slide length. They both utilize the same magazines. The 17L is a good enuf gun for USPSA shooting but is way too large in overall size for IDPA. I have a 2nd generation 17L and just love it.
