I had a 360PD and mistakenly traded it off, but liked it so well, that I was able to get the newer M&P 360 which has the matte cylinder and trijicon night sight. So two questions -
1.) What about the cylinder marks after shooting? What are they? Though they seem to be superficial, would there be permanent damage?
and
2.) What's the deal on the night sights? Visible glow? Low-light? Any issues I should be aware of?
Thanx in advance
