Did some shopping around, this was the best price I had found. Shipping was free and it arrived in 2 days, perfect condition/original packaging. I have a Sig365 XL slide/FCU swapped into a Wilson Combat 365 X Macro Grip Module which has a 1913 rail system. The #5 key that comes with the TLR allows for the light to fit as flush as possible against the trigger guard. Light is super bright, instructions were clear, strobe mode is easy to turn on/off. I’m a fan of the longer buttons that come with the TLR. Definitely would order from this website in the future.
