I've run a TLR-1 on a 226, and it fits nicely, but I really think you will like the INFORCE APL as well. It is lighter, being polymer, a little shorter, and I like the paddle system a little better. I believe it is a little less expensive also.I've been wanting a weapon light for my P226 TacOps, too.
I want a perfect fit and was wondering what was best.
I'll look into the models they suggested for you, too.
