I think I'm getting a set of Trausch grips for my SP101 (have not heard back from seller yet). Now I hear that the grips for SP101's before or after 2010 are different.

Ideally I would like to put these on my 4.2" but it may not work. Any idea what the difference that may cause them not to fit would be? Any ideas for solutions (other than buying an older SP101 obviously). Are odler SP101's available with the same style of adjustable sights as the 4.2"?

Thanks.
