Lightbourne - If your P229 is new, the springs should be compatible with the E2 grips without the whole kit. I just bought a new P229 from TGS that came with E2 grips and tool. Unfortunately for me, I have large hands and the E2's felt too small to me. I purchased the standard Sig grips and screws and now have a set of E2's that have never been used. If your interested in the grips, I'd be happy to sell them.
