RIA General Officer Model M15 .45 ACP Serial Number GO609 - pictured with original belt, buckle, holster, mag pouch, two spare wrapped magazines (numbered to the gun) and cleaning rod.

RIA General Officers Model Serial Number GO609 - The M15 was manufactured from 1972 to 1982.  The frame and slide selected for the M15 were taken from unreworked arsenal inventory 1911A1 stock.  To remove the original 1911A1 markings from the slide and frame, both had to be ground and polished.  The thickness of the frame is approx. .016" less than that of the 1911A1.  The length is the same.  The slide is cut down and modified.  The width is .025" less than that of the 1911A1 and .75" shorter in length.

The lock, safety mechanism, hammer, grip safety, mainspring housing and slide lock are made from standard 1911A1 parts.

These pistols were finished with a deep blue finish on portions of the slide and frame.  The safety, slide lock and grip screws have a polished blue finish.  The top of the slide has a matte type finish.

Serial numbers were changed to "Serial No. GO 609" type.  The markings started with number G01 and went to number GO1004.  The engraving is filled with either a white compound or mixed with a gold color.  Most of the earlier guns have white, but it's not known when the transition to gold occurred.

The placement of the serial number created a problem for engineering with the fitting of the Herrett grips.  A jig to remove part of the top of the right grips to make the serial number clearly visible.  The grips are sharp checkered, oil finished walnut with an Rock Island Arsenal emblem in the right grip.

Silver plaque in left grip is inscribed to MG CHARLES D. PALMER

Sights are fixed National Match on the rear for the first 300 pistols, after which the rear sight was cast and purchased from a supplier.  The front sight was manufactured at the arsenal.

The front grip strap and arched mainspring housing are grooved vertically and horizontally.

Chrome plated National Match aluminum triggers with front grooves and an adjustment screw are standard.

Magazines are serial numbered to the gun and a total of three were shipped with each pistol.
