I own a 1911PD1 and have shot it very little. I bought it used, and one of the things that was different, someone had installed slim grips on it.
I love them! Did not know about them before, but have now put them on my 1911as well! Have a problem with initial cocking. Don't know if the shorter action required a stronger spring - but in my old age am having trouble cocking the action. No problem tho on my full size 1911!
I also don't like the long trigger, and not having rounded edges like on an A1 action--- it affects my grip!
