5906 Barrel Question

[Dguildguy]

Greetings All!

New here and just picked up one of the police trade in 5906s. Needs a new barrel. Hood is .395" wide. S/N available if that helps. Having a rough time figuring out what fits and what doesn't. Called S&W, absolutely no help whatsoever. Basically they said "Send us the entire gun and we'll see if we can fix it." All I wanted was the part number of the correct barrel for my pistol. Frustrating. If anyone here has knowledge to offer I would deeply appreciate it! thanks!

Welcome to the Forum, Don!

I can answer your questions, but I can't help wondering why you need a new barrel?

Anyway, the Models 5903, 5904, 5906, 5923, 5924, 5926, 5943, 5944, 5946, 915 (all 4" 9mm pistols) shared the same barrels.

HOWEVER!!! As you have measured, the LATER barrels have the wider .395" barrel hoods.

The earlier barrels had a much narrower hood (approx .25").
While I have seen them installed in the later wide hood slides, it is NOT something I would do.

The S&W part number for the barrel you seek is 276210000.

Be advised that the 4" 9mm TSW barrels are the absolute latest barrels and although they do have the wide (.395") hood, they have a different angle on the decamming lugs and are NOT compatible with the standard model frames.

Also the Models 909 and 910 ("Value-Line" pistols), while having 4" 9mm barrels with the wide barrel hood, lack the front locking lug of the model numbers previously mentioned. (BTW, I have also seen them installed on front locking lug models, but again it is NOT something I would do.

I'll look through my parts stocks and see if I have a spare barrel (probably) but first I ask you again, why do you need a new barrel?

Thanks John! The crown of the current barrel has a crease or gouge that is deep enough to hang up a fingernail in. I suspect this pistol was displayed on one of those wire stands and the person placing it was less than careful. that or someone smacked it into something. Either way the crease is deep enough to cause me to suspect its safety. Cannot return because I took delivery (GB small print, pays to read that!).

Just my opinion, mind you, but if it is indeed a gouge and not a crack penetrating the full thickness of the barrel steel, and an inspection of the remainder of the barrel displayed no other signs of integrity compromising damage, I would assume the barrel to be safe.

"Accuracy" (such as it is on a "combat Issue" pistol) may be compromised by a damaged muzzle.

I'd shoot it first and if it really spread out the pattern I'd get a round head brass screw large enough to "chamfer" the muzzle and go at it with some valve grinding compound to "pretty it up".

All in all, a much cheaper solution, and furthermore, your barrel already fits your pistol.

There is always a chance a replacement barrel may require some fitting and may be no more "accurate" than what you've replaced.

Took one look at your pic and had a flashback to the 90s. My barrel looked exactly the same after I used a punch with a square body to punch out a squid bullet. When the bullet moved the punch slipped and the square edge dinged the crown just like yours.

Anyway after $45 and a recut crown the barrel was good as new. As long as the gouge does not go full thickness all you need is a recut crown.

I don't think that damage came from a wire rack display, something more substantial hit that barrel. Before spending money on a new barrel, I'd see about having the damaged muzzle re-crowned. A lot of S&W pistol and even revolver barrels will do better after being re-crowned.
