20 years ago you sent your 1911 to the best builder of the time (Mike Curtis) and for $750 he returned a 1.5" 50 yard target gun. Todays numbers are astounding. The X ring on the 50 yard slow fire target is 1.695 inches so you really wanted a 1.5" gun. Just knowing the gun will do it if you do your part was confidence. Mike's gun and test target with ball ammo at 50 yards. 1.375" x 1.817" with one flyer, 10 rounds.
