I love my new (02/2010) SP101 357. So much so that I bought a monogrip and meprolight front sight. I just finished punching the roll pin out and the sight did not budge. The sight is NOT pinned in, just appears to be glued to the top. Looking thru the pin hole its clear that its smooth all the way through. Pushing a pin through the hole encounters no resistance or roughness from one end to the other. The manual still states the front sight is removable. What gives? Anyone else have this problem? I just wasted 40 bucks on the front sight apparently. WTFF RUGER. Buyer beware.
