I’ve had this P320 for a while. I switched to this from a Glock 48 MOS and am no looking to switch to something new. The optic does have a crack in the glass but overall its mechanical ability to hold zero hasn’t been compromised. I don’t have a printer or don’t know anyone with a printer that can help me get an RMA printed and filled out so I can send in the optic to Sig so they can fix it. I’m willing to negotiate on price. Without the optic I’ll let it go for 880, with the optic 1179. It’s fair to cut the value of the optic in half considering the crack. Again, mechanically the optic is sound. The crack doesn’t interfere with the dots line of sight. If interested text me at 8three2-9two1-13seventy2
