Terminology: Round Butts and Square

posted on December 7, 2011

Older revolver catalogs used to list two basic butt shapes for their products—round and square.This actually meant slightly different things in the literature of the two big pre-World War II gunmakers—Colt and S&W.

For Colt users, round butts involved a light rounding of the lower corner of the revolver butt, front and back. Smith & Wesson's use of the term involved rounding the corners and slimming the back strap.

Further, the Springfield product enjoyed a slenderizing of the front strap, so much so that you needed a different length mainspring screw on the two different K-frame guns.

Just thought this might be interesting to a few.
