Hey,

may be picking up a 25-? think it's a 5, in 45 colt. Unfluted cylinder, 5 inch or 5 1/2 inch barrel in blue. I'm interested in being able to shoot 45ACP out of it since I sold a 625 in 45acp a long time ago and have never replaced it.

Can I use 45ACP with full moon clips in the gun or since the ACP rebates on the case mouth, and the 45LC on the rim, would it not work?

I've already e-mailed the S&W custom shop about fitting a new cylinder to the gun in 45ACP, but they haven't responded yet.

Anyone have any information or personal experience?

Thanks.

You'll need an ACP cylinder. Probably not a cost effective idea. My admittedly limited experience with convertible 45's is they will shoot one caliber well and the other caliber poorly.

+1. I've also read reports where the Ruger Blackhawk convertible from .45LC to .45ACP (using a different cylinder) suffers from accuracy loss when shooting the ACP round. Maybe the cause is the extra distance the ACP round has to travel down the cylinder before it hits the barrel?

Exactly. Friend has that very same rig. With the Colt cylinder it is a tack driver. With the ACP its barely a good shotgun.

If memory serves the rifling of the Colt and ACP differ slightly but enough to affect accuracy.

If it's an unfluted cylnder, then it's not an original 25-5. I'm not too sure they made an unfluted cylinder in the model 25's like they did the 625's?????

Bullets are sized a bit differently and the rifling on a .45 Colt BBL tends to be shallower I believe.

I had a 25-5 with an 8 3/8 inch barrel in nickle. Very accurate and easy to shoot. Mine had a fluted cylinder.

Traded it for a Ruger Security Six and $300 in cash. Guy wanted it real bad.

Wish I had it back.

Update: Per S&W they can't do the conversion because the cylinders are different lengths.

So I either pick it up for just the 45 colt, or pass on it.
