I don't know how far this will go but I'm keeping my eyes out for a decent broken laser sight for my xdm. My goal is to retro fit it and still keep it spot on but with a blue laser. I know a bit about electronics and different aspects. I am confident I can build it. but the question remains. 1. will it be durable enough for pistol mount. 2. will it be able to hold its sight. My search has begun and hopefully ill be posting some range proven pictures before you know it.
