25-2 .45 Colt

[steelslaver]

I did not want dual cylinders. Started with Model 28-2 and fit a 25-2 cylinder. About the 10th or 12th reload, I noticed the lug was beating the cylinder or the other way around. Used an arbor press to punch out the old ring and to punch in the new one.

How can one not notice the running start of the cylinder prior to ejecting the brass?

The running start is only goes for .040 distance. I never made it a habit to slam the cylinder back. i usually open the cylinder muzzle down roll it up and then eject. As you roll the muzzle up gravity should slide the cylinder back against the lug. I don't see how an cylinder and empty brass is heavy enough to get enough energy sliding .04 of travel to batter the steel lug.

But, then I gave up on dual cylinder guns. Just because changing cylinders is a hassle Even with an extra yoke. Only dual guns I have now are via the recessed method.

But if you use the recess cut in rear of colt cylinder both cylinder will have minimal rearward movement against the lug

I suspect you are right! Although, it could be a 25-5 that was mismarked. I suppose. I remember when Smith did not make a .45 Colt, and when they brought one out it was only in four inch, as a normal production gun. Later, they added the longer barrels. They didn't make a four inch 25-2 back then, either. But, I have to wonder why someone would convert a 25-2 into a 25-5 configuration? Interesting.

Is the cylinder long enough for this conversion if it were originally a 25-2?

I just measured my 25-2 with dual cylinders.

The 45 Colt cylinder measures 1.667"
The 45 ACP cylinder measures 1.537"

I also have a 25-3 which is only chambered for 45 Coit.
The 45 Colt cylinder measures 1.667"

45 Colt ammo specs are 1.570" OAL.

In addition to the overall length of the cartridge in the cylinder, I believe it will also require enough length to accommodate the cylinder throat......Ben

There's no way to make a 25-2 45 ACP cylinder work to fire 45 Colt.

Easy button: Install a 25-3 cylinder. If one could be found.

I used to own a pinned barrel 25-5 with a green ramp / White outline sight set. Liked it a lot. Lost it in a burglary in the 1980's.

I don't see that in the supplied pictures but it is possible.



Are you sure about that? I agree the majority of the Model 25-2 revolvers came with a Patridge sight but I have not seen a Model 25-5 that did not have a red ramp.

I seem to recall that perhaps a handful of .45 Colts were produced prior to the 25-3. No reference, just a dim memory. Old man who's had a few cocktails this evening.

Measure those cylinders again. The acp cylinder may be .030 shorter, but not 0.130 shorter

epj yes some 45 colts were produced before the 25-3 strictly on a special order and very few of those

Yes, there were some of the Model 1950, 45 Target revolvers built to accept the 45 long Colt cartridge. Not many, maybe a dozen?

Correct you are! I added .100 to the 45 Colt cylinders by mistake. The difference is in fact .030".

Your pictures clearly show the pin that secures the barrel to the frame is buggered notably. If the pin was removed, the barrel was probably changed. Neither 25-2 or 25-5s normally have a red insert in the front sight. If you lettered the gun you'd probably find the gun left the factory with a 6 1/2" barrel and Patridge front sight. Someone later on switched the barrel to 45 Colt. The cylinder has probably been changed to 45 Colt or reamed to accept 45 Colt cartridges.

The gun is a homemade shooter, not a valuable "one-of-a-kind"gun.

25-2's with factory red ramp front sight are not common, but they aren't rare either. I had one, and have seen a few others.
