I own two LDA limited models. A 7.45 and 18.9. Haven't had em but a few months...no problem with sights coming off, but after reading this forum, they inevitably will come off at some time. I was wanting to replace the front and rear sights with tritium night sights (just like everyone else!) I haven't been able to find an easy solution to this problem. Looks like I need the front and rear dovetails to be remilled for B0-MAR or similiar. I understand the adj rear sight is an LPA, and I would think that LPA sight company would offer a "drop-in" tritium night sight for the limited series LDA. Apparently they don't. Does anyone have any other info for replacing the front and rear sights with tritium, or do I need to get them both remilled?
