I have two 1911's with checkered front straps, and MSH. Another one with the "chain link" pattern, don't care for it.
But after carrying the two checkered ones (one CCO, one full size). I now put skate board tape on any pistol with a smooth front, including my K9 and MK9. Just feels right. I have not tried the Wilson Combat add on, mentioned in another thread. The recent RIA 1911 in .40SW has a few lines down the front strap, similar to a Beretta M9. While not as grippy as checkering it works pretty good. Since I carry a 1911, most of the time (K9 on hot summer days), I worry about slippage when the SHTF.
