Got the FH from Numrich..Quality is quite nice. Did some measuring..and cut 4" from the #4 barrel....and the FH slipped snugly into place. Fits perfect..I broke the sight insert while switching it to the FH. Where can I get another ?..And..Were any 15 or 20 round mags. ever available ? I'll post some pics. when I'm done..Thanks for the help...
