I'm certain that your Officer's Model Match can handle +P ammo though it isn't warranted for it. It won't blow up if that is your concern however it's reason for being is as a target revolver, a function it capably handles. If a person was required to utilize an Officer's Model for defensive use then the firing of a cylinder-full or two for familiarization won't affect it and it could be kept loaded with +P ammunition for personal protection.
One sees a lot of questions about the use of +P ammunition in various models of .38 Special revolvers, both here and over on the S&W forum. It makes me wonder whether some folks are intent on feeding their revolvers a steady diet of +P ammunition, a puzzling practice in my view. The stuff is expensive, loud, hard recoiling, and not generally a top choice for accuracy. None of which are appealing to me in my use of the .38 Special at the target range. If a person feels that he must extensively practice with heavy .38 Special loads it'd be a shame to use a fine Officer's Model Match for the purpose. It will wear parts that are not so easy to come by. I'd recommend a late vintage Colt Trooper Mk III or a Lawman for such use. Or purchase a Smith & Wesson Model 10 Heavy Barrel for dedicated use with heavy .38 Special loads. I've had one for over 30 years and fired a jillion rounds through it. It's nigh onto indestructable.
I'd be thrilled to save the Officer's Model Match for "Sunday driving".
It is safe. The long term effects will be wear on the parts that turn and lock the cylinder. Work on these parts will cost plenty. I only use wadcutter loads in my target guns and shoot +P loads in guns chambered for magnums or 38spl carried a lot and shot little.
