Anyone have problems with this pistol? All reviews and tests rate it very high and reliable. I have had no problems in the first 200 rounds. It fired flawlessly and deadly accurate at 10yards. Last week while at the range I noticed the take down pin coming out after firing a clip. I just pushed it in and thought nothing of it. It did it again in a few more rounds. It was cleaned and inspected and nothing was found. Yesterday while at the range and after firing a clip of 6 the pin was almost all the way out. I pushed it in and after the next clip it did the same. It almost fell out! I just sent it to Taurus so we'll see. I hope it's not a flaw, it is really a great pistol.
