Beavertail Safety Question

I have a '60's Colt NM 1911 and would like to install a beavertail grip safety. Does anyone have experience with specific choices for one on the pre-70 series models? Thanks!

Most, if not all, beaver tails require rounding the two lugs on the frame.  This permanently modifies the pistol.  So, if your pistol is a complete and
Unaltered 1960s Colt NM, modifying it will destroy any collector value.

I believe that Wilson has a beaver tail safety the will fit an un-modified frame.

Never used one, but a call to Wilson should answer the question.

Wilson does make a beaver tail safety that will fit without modification to your pistol. It is unsurpassed for ugliness!
If you have a nice old Colt, please don’t consider cutting into it to fit a proper beaver tail safety.

Just assembled a conversion lower with the Wilson combat & had no issues.

I won't cut into it. The lugs are already rounded. This was a hand-me-down (but a pretty nice one at that).
