Let me preface this by saying I carry a standard surefire G2 with me everywhere I go. I will continue to do so regardless of what I decide to do next. I have been reading a lot of reviews and doing a good bit of research on the streamlight TLR-1 and have determined that is the light I will buy if I go this route. This will be for a new rtf2 G17. It is my new carry gun from now on. Anybody heard of any significant reliability issues with lights on the 9mm glocks? I realize every gun is different, but that seems to be more of an issue with the .40 cal glocks. I have checked on a holster from Bladetech to carry the new setup. But it states it is for a glock with a surefire x300. Does anybody know if it would work with this set up? Please keep the comments about what and how I want to carry to yourself. I am accustomed to carrying a full sized steel frame 1911 so weight and bulk do not bother me in the least. Thanks for any help in advance.
