Is ther a suffix preceeding the SR number? There are two models, pre war and post war. We need to distinguish which one you have.
Please provide the information stamped on the gun.

There were two different Ace models in addition to the conversion unit.

The first, original ACE, was made 1936-1941, with a few assembled around 1947 from parts. About 11,000 were made. The frame has only the serial number and the Colt VP with no other markings. It uses a Gov't Model frame without an ejector, and a special smaller and lighter slide and recoil spring. It does not use a floating chamber.

The second, the Service Model Ace, uses a standard Gov't Model frame, and a normal size slide. It has the floating chamber which increases felt recoil to give a feeling more like that of the .45. It was made in about the same time period, 1935-1945; about 13,000 were made. The serial numbers begin with "SM".

The Conversion Kits have been made since the late 30s and usually kept up with the latest style of slide used for the civilian Gov't Model. They are still made. The conversion units use the floating chamber.

At a gun show a couple of years ago a guy was selling a Service Model Ace made around 1980, LNIB. I nearly choked when he told me he wanted $1,100 for it.

Well, Jimmy, the latest Blue Book lists the Colt Service Model Ace in 100% condition at $2600. Maybe you should have bought.

Ouch! Well, it sounds like another addition to my too-long list of guns I've kicked myself over for not taking home with me! :o

Jim K. please advise where to get a new make Colt Conversion. They did not have them on display or in literature at SHOT.

Philiphogarth, I think your Ace SN is high enough that it is one of the ones made in the 1970s, early 80s.

I have one from that period but it is on a 70B Gov't Model frame (bought new by me as a complete gun, it is not a conversion left on a centerfire frame.)
They were apparently not to careful what upper they put on which lower, there are a fair number of SM numbered .45s out there, too.
