I am also a new owner and my ambi-safety keeps coming loose/popping out along with the take-down lever which is so loose it stops the slide from cycling. The only way I can fire it is to hold the lever down with my left thumb until the ambi-safety comes loose again. I have tried repeatedly to have push/tap it back together and it comes loose after a few rounds. I still seriously love this pistol and can fix it myself, with new parts, I assume. I have hesitated in sending it back to Taurus as they are outside the US and I really don't like sending my favorite pistol outside the States. Any ideas? :???:
