Good / american made but could be better - Streamlight TLR-1 HL CR123A LED Rail-Mounted Tactical Flashlight

Bought this for glock 20. It is real bright and solid. Light build looks good and made in USA which I like. Switch function is easy enough and pretty convenient. The price is not cheap, but much cheaper that inforce / surefire. Now why it could be better - I had to youtube how to open battery compartment so I would not break something trying to figure that out. Also install on handgun rail is not super easy and takes time. I have chinese lights that literally can slide on rails in second. This takes a good minute or 2. The tightener requires coin to loosen. Also makes easier to tighten without tightening it too much. All in all it is not the most user friendly light imo. I can over look it because as said it is quality, bright, american made at fair price. One thing I have hard time overlooking is they don't have the cap with port for external cable as being standard. Most of us who own handguns own tact rifles too. Seems like they should have the port available standard. I do not understand why have to buy whole new end cap with cable port for $50! This is a failure of Streamlight to not have this 69130 cap standard especially for price paid. I could have bought olight Valkaryie ( Chinese made) and had same thing basically for function and lumens at under $100. So this is the biggest thing they need to correct- the end cap for batteries. I gave it 4 stars which seems fair and I will begrudgingly recommend as is solid and made in USA but it could been made better / 5 star. Get to work Streamlight!
