Tony,
I have a S&W M-69, the L-frame 44mag, any options? You list the IWB#3 for the K-frames, but no L? Also, it is the five shot cylinder, so maybe not molding into the flutes would probably be best (never know if I might end up with another L-frame).

PS: Just ordered the M&P 2.0c, nice that is on Quick Ship.
