Welcome to the forum. What doesn't your wife like about revolvers? Has she had much use of a semi auto to compare? The LCR is a stout little gun even with +P but I carry my LCR357 as my main carry every day. I have become more of a revolver fan, maybe because of the safety and reliability of it over a semi auto.
RT has a ladies section your wife might be interested. Any way glad you came aboard and have fun among other things here at RT.
