What's up, I am thinking about buying some new/extra LPA Sights to go with my factory sights , which are the LPA sights and very very good (I've read that they're the best , but I am definitely not smart enough in this field to render opinion nor experienced enough to even compare and contrast.) So as people may or may not know the 930 SPX comes factory installed with a rail, and an LPA adjustable ghost ring sight "mount" and "circle" aperature in the rear and a "M16" style "winged" front post aperature with a red, fiber optic rail tube for gathering available ambient light. It is awesome in my opinion and I love it. But I am also into night sights/tritium and I think its necessary... Especially for a dedicated combat/HD shotgun which is what I use my 930 SPX for and really what it was designed for. So I am wondering if anyone knows how hard it will be to change the factory supplied stuff for some new/extra gear also from LPA. I am about to buy night sights for it [Consisting of a tritium ring aperature which replaces the supplied ring and a tritium dot tube up front replacing the fiber optic rail tube.], and also probably/perhaps the dual fiber optic rail-rear ring aperature... If this works easily and I hope it will, and if it's possible to switch them myself and furthermore if it's easy to pop them back and forth (Like switching between calibers on my Glock 23 by swapping the proper barrel and then appropriate magazine, sort of ?) I will then keep the night sights ghost ring and front and have that on most of the time, but also would like the fiber optic rear to go with the fiber optic front, and would pop them on for range trips/fun shooting outside/etc. and occasional targets and like clay stuff shooting. Don't do a lot and I know it's not designed for that nor is it one of those $3,000 Italian over under johns, but whatever it goes boom just the same. So does anyone have any experience with the LPA Sights on the 930 SPX etc. or other input, thanks much. Just so you know, what I'm talking about, http://www.lpasights.com/catalog-shotgun.html and then scroll around, I have ghost ring D4 (standard) , I would buy D3 (Tritium) and probably/possibly D5 (dual green fiber optic tubes) and then for front, I have front fiber optic M1F (standard on 930 SPX) and would be buying M1T (Tritium) .. Thanks much for the help and input. Wanna kill these ads? We can help!
