I have been considering a weapon mounted light for my glock 23. I have narrowed the field to Surefire's X200 and Glock's GTL21. GTL 21 X200 Light/laser light 173.00 250.00+ bulky small unknown durability proven profomance finger activated pressure switch or finger I know alot of guys use the surefires but has any one heard any negatives about the glock lights? For the price I am deffintley leaning towards the glock. Size is not as important since it is a night stand gun. Any comments or info would greatly be appreciated! Thanks!
