Own 3 here. 1 non safety that i carry daily, a manual safety that the wife carries daily( wont carry a semi without a thumb safety), and a manual safety I bought "used" from a friend who fired 2 mags through it and didnt like it. Mine has over 1k rounds through it, wifes has around 700, 3rd has about 400 all without any issues whatsoever. Also have 2 12rd mags for each and 1 15rd. Am picking an XL up tomorrow that my local FFL has put aside for me. The originals have proven fit me well, to be very reliable, and I find i shoot them extremely accurately(for me). Looking forward to shooting the XL.
