Is it safe to fire +P 9MM in the S&W 5906? I have one of the surplus Police Pistol trade ins from CDNN.
Thank You

Yes - even +p+ is going to be OK in that gun. US SAAMI spec for .38 is 17k, and +p is 18,500k. Until flyweight revolvers came around, .38 standards were 20k. Currently, in the rest of the world, CIP standards are used and .38 special is 22K, with no "+p" recognized! Hint: they don't use weaker barrels in the US market guns.

Ummm the 5906 is a 9mm, not a .38.

+p is 100% safe in the 5906. It's probibly the most stout 9mm ever made.

My department used to issue the 5904 and 6904 and all we ever shot was WW +P+ 115 grain JHP. These pistol had the alloy frame and I never saw a single problem firing this ammo but I heard rumors that our Tactical team guns had a few parts replaced. Most of these were extractors, firing pins and maybe a hammer or decocker\safety. These pistols had from 40,000 to 50,000 rounds on up while the rest of our pistols had a few thousand rounds through them. I had a range officer friend who worked for the Department when the investigators carried double action revolvers. He said some complained about semi auto pistols reliability but most revolvers would have been in scrap yards long before any of the semi auto pistols. This pistols just didn't go out of time or wear out like revolvers. I've carried the 5904. 6904. 3913. 439 and 39-2. The 39-2 I bought in 1975 and I had to have the hammer replaced because the hook where the sear engaged wore down. All but the 39-2 had lots of +p+ ammo fired through them and never seemed to hurt the pistol. I chronographed this load at 1300 fps plus out of the 439 & 5904 4" barrel and 1250 to 1275 out of the 3913 & 6904. I'd say as long as you use good quality +P ammo in your 5906 and the bullet doesn't get pushed deeper in the case on feeding you should be GTG.

Why would it get seated deeper?

If a bullet gets deep seated (even by a small amount) the pressures go sky high and can destroy a pistol. Its imperative to put a tight taper crimp on ammo to be used in a semi auto. Anyone who carries a pistol for self defense and regularly unloads their pistol would be wise to rotate the top round in the mag so your not chambering the same round all the time. I'm sure some of the reported blown up guns are caused by the bullets being pushed back into the case. Back in the early 80's WW had a lot of 9 MM brass that was bad. You could not reload with some of this brass because it wouldn't hold the bullets tight enough.. Some military and commercial ammo for semi and full auto weapons actually have a sealant or glue which helps prevent bullets from being deep seated. One other thing to save your extractor is when loading your weapon do not drop a round in the chamber and close the slide. Its always better to feed a round out of the mag. This saves a lot of wear and tear on the extractor. When feeding a round out of the mag the rim slides under the extractor. If you drop the slide on a chambered round the extractor has to snap over the rim of the chambered round. This puts added wear and stress on the extractor.

All:
I apprecieate the response. I really like this pistol. My wife bought it for me last Christmas. I suspected this to be the case about handling +P ammo. I really like the craftsmanship and durability built into this pistol. I don't feel like it will come apart at all when shooting it.

Shoot with confidence! I have a 6906 (just like the 5906 but in stainless) and it will shoot anything. I love these guns. Wish Smith still made them.

The 6906 is the compact version of the 5906. Both are stainless.
