I heart my crimson trace

The cool thing about Crimson Trace is that they make really compact laser sights that don’t add hardly any bulk to your pistol or other fire arm.  I have to clarify because they used to almost excluseively handle pistol grips but the line is expanding some.  They also carry AR style fore grips.  That makes a pretty cool addition to your tactical rifle.  The laser foregrips area actually a combination laser and tactical light built into the grip.  They are independantly activated and clip to a picatinny or weaver rail.  Some times there is very little difference in rail types.
