I went with the 105 and have no regrets. The 305 was of no interest to me, and I found the 405 to be harder to draw from dress slacks (my J-frame's primary, and nearly only, role) thanks to the rubber texture.

I find the opposite hand to be the problem; as a left-hander, I've found that my left thumb sometimes obscures the laser path on 105s, 205s and 405s when I grip with my thumb straight, and have to always remember to flex the thumb in order to avoid this.
I have all three of the above Crimson Trace grips on different J-frames, and I really find that the 205 feels most natural in the hand, though as Tam noted, it's unfortunately no longer made. The 405 is certainly the most fully cushioned, and also narrower than the others, and seems to fill the hand (or at least my hand) the best of the available models.
"Therefore, since the world has still... Much good, but much less good than ill,
And while the sun and moon endure, Luck's a chance, but trouble's sure,
I'd face it as a wise man would, And train for ill and not for good." -- A.E. Housman
I've got the 105 on a 642 and I am right handed. I've never had any problem with blocking the laser when shooting. If I were doing it all over I'd go with the 305 to get the better grip, but I don't find the 105 to be an issue.

I went with the -105 grips. I can handle the 442 with the stock grips (not a lot of fun, though) and a couple of folks away from here also recommended them for the lessened chance of snagging in a pocket.
Thanks for everyone's opinions. This place is great!
