At the least you would need a hammer and pin to drift the Micro sight out and then drift the Coltmaster sight in. Personally, I'd be talking to an experienced Colt smith like the folks at Pittsburgh Handgun.
As to the question about the differences between an Officers Model Match and Officers Model Special, the OMS has a barrel that is not tapered, a dual tone blue finish where the front of the frame and the flutes of the cylinder are flat blue, the rest of the revolver is high polish blue (except the end of the barrel which is "in the white"), the Coltmaster rear sight assembly rather than the later Accro, came standard with "Coltwood" stocks (plastic) and the front sight ramp is longer than the OMM. Oh, the OMS was only made from 1949 to 1952 and in my opinion still show most of the care in manufacture exhibited in pre-war Colt revolvers. Fine shooters.
1)Thanks for the information regarding Pittsburgh Handgun!
2)I agree that the rear sight should be changed out for the original Coltmaster! However, I don't want to risk damaging this revolver by attempting to remove the rear sight myself-nor, would I feel comfortable sending this gun out for this work(Because anything could happen to this gun!)! Once I have learned the exacting proceedure for removing this rear sight, I would possibly then, attempt to remove it?
3)I know where there is a good shooter grade Colt Officer's Model Special-and, I have been watching it! The Gun Shop that has this Colt, wants $450 for it! I might be able to obtain it for $400? I just hadn't decided whether or not it would be worth it to buy an OMS like this, just to shoot it? Although, it might be fun, sampling one of these great old target guns, at my local Gun Range? Although, I've got a lot of brushing up to do, as I haven't fired any guns in at least forty years!
1)Do you also happen to have an Officer's Model Special in the .22 caliber? Although I doubt that I'll ever be enabled to find another Pristine OMS, I sure would like to find one of these as a perfect mate to my .38 special, OMS?
2)No, I don't have any experience in removing sights from guns! With the proper tools and instructions, I probably could do this job? But, I still might not want to take such a risk? It would be very easy to make a mistake and mar the finish on this OMS(Etc.)!
Great pictures and very nice condition gun and box. Your Colt is such a limited production piece, I would not attempt the sight change. Put the proper, original sight in the box with the gun, as is, and don't attempt the change. I have a similar Shooting Master situation, don't chance a slip or some damage. Your OMS is too nice, keep as is...
Thanks for the very wise advice! I would rather keep the gun intact, rather than to risk the consequences of fumbling the rear sight replacement! And, this is the reason that I had never attempted to reinstall the original Coltmaster sight!
I looked at the Coltmaster sight on the shooter grade OMS that I had mentioned above-and, I must say, that I do like it much better than the replaced rear sight on my OMS! I'd guess that some of those old Colt target shooters, evidently had thought that they could improve the already great performance of the OMS by replacing the original Coltmaster sight with a non-original one(Probably to no avail?)? If my understanding is correct, the Coltmaster sight was a pretty good one?
From some of the older shooters I knew the OMS and the OMM just wasn't as popular because of the sights. They all preferred the original sights of the OMT or a King's sight. You know how the old geezers can be set in their ways. /forums/images/graemlins/laugh.gif:
I do not have an OMS in 22. We do have several other OM's in 22 though.
For my money, one of the best things about the OM's is that most all, even pristine examples have been shot. That's great, because then we can shoot them without harming them in any way.
We intend to expand this part of our collection somewhat, with models, and versions we don't presently have.
One of my major annoyances about gun collecting is the NIB guns, particularly Pythons, or ones that are so nice, that you risk harming them by shooting. We are seriously thinking about culling some of our safe queens because they have pretty well hit their zenith in value for some time to come.
Being an old geezer myself, I guess I appreciate guns from my own generation.
How about the later OMT's with the factory Colt heavy(Tapered)barrel in .38 special? Are these nearly as desireable as the edition that came just before this heavy barrel version? I ask this because there is one of these in a gun shop that has been sitting for several months(Unsold!)despite this OMT being in 98% or better condition! It has a 6-inch barrel.
From what I learned the heavy barrel models were very popular especially in .22lr. The .38 spl and the few .32 Colts were given heavy barrels so the set would match. As to the individual shooters I think it was split between those who wanted a heavy barrel and those who wanted the older standard barrel. Just a personal preference thing as they all are great shooters.
I've always wondered about the ramp for the front sight on the OMS and later guns. As some ramps are longer were they adjusting the muzzle weight? I've never seen or heard any reason for that. Someone here is bound to know or heard an explanation.
I stand by my recommendation that if you are going to replace the rear sight assembly, have it done by a professional. I have done business with Pittsburgh Handgun and would trust them to do any appropriate work on a Colt of any condition.
The replacement of Coltmaster sights is not as rare as some might think, I've also got an OMS 38 with Micro rear sights, I actually prefer them to the Coltmaster on my OMS 22 when shooting the heck out of them at the range.
Good luck with whatever you decide. FWIW, I'd probably do what others have mentioned, just put the Coltmaster in the box and leave well enough alone. A lot less expensive too.
