Since drop in parts have already been addressed, I'll coment on the stag grips on a 1911. I love the look of stag on a 1911. I have some panels made by Ajax that are from The Sambar deer, they are made thin, and they are smooth and yellow from being around so long. Also had Eagle send me some American Elk horn grips, these are thicker, and also good looking. My SA milspec looks good to me with those smooth yellowed stag grips on it. I never cared for the wrap arounds myself, but all that is personal prefrence. I found that my shirt would sometimes hang up on the soft rubber grips, and get stuck on them if I bent over or something, so I went to smooth grips. I don't think you would be disapointed if went with stag...they look neat.
