I'm really close to desiding on purchasing a Crimson Trace Laser grip for my rail equiped .357 SIG 226. Is there any down side to owning these in respect to reliability, zero hold, fit - finish. I'm a "Joe Citizen" who will use it for home defense or if Osamma comes to dinner. Will plan on range use of about once every other month. --- Must say, with the extra barrel I have in .40, and the M3 tac light on it , to me its just about the best choice I think I could have made. Thanks--- John...
