Ok guys now that I'm getting my 229 thanks for everyone's input was wondering what you are using on your rails . I was looking for a laser but wanted something that's not to big . Does sig use a rail that limits what I can use . Thanks in advance Stephen

Streamlight TLR-7, TLR-1 or Surefire X300 is all you really need.

The SigTac laser + light STL900 is available at low cost. It protrudes from the front of the slide, apparently made for the P226.

For what it’s worth, I have a tlr-1 on mine. I have found light bearing holsters hard to find, and impossible with a tlr-7.

Don’t forget about the pistol bayonet!
