In terms of money spent to make the USRA, it is absolutely one of the finest when comparing how much it cost to produce each one. Estimates are that H&R spent around $150 to make each one, sold them for around $35-40 each just to prove they could make the finest single shot target pistol, which ended due to WW2. It ejects the MT case at high speed, self pushes the bullet directly into the rifling thru the use of a short chamber S&W dubbed an "Olympic Chamber". It is also estimated no more than seven of the pistols are alike, due to Roper's constant improvements, as well as all the variable options. In order to hire Walter Roper away from S&W, he was given an unlimited budget, which explains the high cost per pistol, each one produced after he took over is stamped with an "R" & sport Roper grips.
