Why not just Google "1911 grips," and follow all of the leads? There will be hundreds.
My own experience leads to these observations:
• Eagle Grips does good work.
• Esmeralda does good work.
• Brownells is honest about everything they sell.
• Dymondwood is just about indestructible, while real rosewood scratches and dings easily.
• Putting rubber grips on a 1911 is a bad mistake. It slows your reload down because it's harder to rotate the pistol in your hand the way you're supposed to.
• Putting checkered grips on a 1911 is another error. The areas of control are the front- and backstraps. Checkering slows the reload (see above).
After looking at various grips, I decided to go with these Roco grips via Brownells. I decided I wanted some thing that would give a very different feel than standard grips. I don't like grips with fingers as they all seem to place my fingers in the wrong place.
This grip feels good and allows me to keep my fingers in the right places. I will be shooting the gun soon so I will let you know how it works for me.
