Bought this gun not to long ago. I have shot about 175rd through it with no issues at all. I did replace the guide rod with a 16# galloway stainless guiderod. The OEM guide rod assembly came apart when I was cleaning the gun. The larger spring shot across the room and I had one hell of a time getting it back on the assembly. I love this gun and Im not sure why it hasnt gotten much love. I see lots of M&P love and of course glock love along with a few others. I would recommend this gun to anyone.
