New SIG P365 & XL ArmaLaser bright green laser sight, TR27GS. Quick on target and perfect for anyone having difficulty seeing iron sights. Cost $150 will sell for $75.

No need to squeeze any button to activate. Without your having to think, this will throw out the most powerful green laser allowed by law at point of aim as soon as you just grip the pistol. Green laser is also much easier to see than red.
