are 442 and 642 J frames really +P strength?

Scroll down to .38 caliber ammunition recommendation, particularly the "Standard pressure (none +P) paragraph, just above discussion of the 9 mm ammunition. Will 642 and 442 J frames be ruined by firing over 100 +p rounds because of their aluminum frames? Is this true? If so, why is the barrel stamped with a +P?

I believe S&W stamps the barrel 38+P because they intended you to use +P ammunition in them.

 

[marine2541]

Yes, and thank you for replying, but will 100 +P rounds ruin the gun?

 

[dlstewart01]

I wouldn't think so. There are a lot of people who have fired many more than that with no issues.
S&W did not stamp +P with 100 round limit.

Just my opinion,

100 rounds of SAAMI +P rated ammo is not going to do any damage to the airweight Jframes.

I had two old boxes of 110gr +P HP's, the hot W-W "treasury" stuff, that I picked up at a gun show. To burn it up, I used it to qualify with a 642 a few years ago, 50 rd course of fire, you go through twice, back to back. I'm very recoil tolerant but this stuff was pretty brutal. In spite of the recoil and muzzle blast the gun was fine after the 100 rounds, I didn't fare so well and ended the session with a sore wrist and two bruised up fingers. It was at least as bad as my friend's M&P340 with 125gr magnums. Anyway, your gun is plenty tough and will handle whatever you can.

No problem with my 642 with C/T grips with the +P's. I have shot atleast 1000 rounds of Speer Gold Dots+P over the past 3 years.

 

[Destructo]

I certainly hope my 642 can handle more than that, I would not be very happy with S&W if the gun blew itself up after 100 rounds.

I suspect its more speculation than anything, the frame is made from an alloy which should be tough enough to handle +P loads if your hands can handle it.

It's a poorly written article, apparently based on old gun magazine and internet hearsay. A clue to this would come not only from the ill founded statement about a 100rd limit of +P ammunition, but also from describing the 89-90 FBI tests as "silly" and then going on to suggest that one follow the advice of Sanow and use Glasers. Mein Gott in Himmel/oy ve.

Older Airweight revolvers were no officially +P rated. However a great many users have fired a great many rounds out of them over the years without harm. There was a test carried out by a forum member (Osprey) where he fired 1000rds of +P through his 12-2 without harm.

Design changes to the current 442/642 allowed them to receive a blessing from the factory.

They may be made to handle +P ammo, but......... I had a frame crack on a new 642-2 about 2 weeks ago and it had less than 100 rounds of standard 38 ammo through it. Since that happened to me I have talked to 3 other people from the gun club that had the same thing happen to them. I have talked to S&W 3 times now in the last 2 weeks and was told the same reason as the others were. The barrels sometimes get over torqued during assembly. This process is done by machine not by hand. When talking to the factory rep about the problem, I was told that they would gladly upgrade my replacement to an all steel model if I wanted to. This tells me that there is more of a problem than maybe they are saying if they are offering to upgrade to all steel models when these models frames crack. I wonder how many are going back for problems. Seems these model also have been having trigger problems too, where the back of the trigger is cutting into the frame behind the trigger. From what I have read the trigger is nor stopping where it should and causing the problem. Seems the trigger only cuts in on one edge, maybe the over torquing of the frame has something to do with that also.

I have a 642-1 at S&W right now getting the trigger problem fixed. Its no big deal. They will make an adjustment and all well be well.

I have three pistols I like enough that I will never sell any of them. One is my CS9, one is 640-1 and the last one is my 642-1. I'm sure there are others that fell the same as I do.

Just my opinion

20,000 rds of +P then send it back for a tune -up.

 

[The Big D]

Well more than 500 +P rounds have been rather happily (for the gun, not for me!) cycled though my 642. No worries.

This seems a bit like a thread I saw in another forum that asked why the manufacturer says only synthetic oil and warranties the engine for 100K miles. Some folks seem to know more than a manufacturer...I wonder why that is?

Be safe.

NO.

Is this true?

NO.

If so, why is the barrel stamped with a +P?

Because S&W believes these revolvers are OK to shoot +P.

 

[HEADKNOCKER]

I've shot +P 125gr threw my 642 No Dash several Times but currently carry New Old Stock Non +P Nyclads in this perticular revolver..
I carry Spear Gold Dot 135Gr +P in my 342Ti as it's +P rated..
This will do untill something better comes along Or I'm Dead..

[shooter429]

Obviously, a steady diet of the hottest loads could wear the gun faster, but they can shoot plenty of +p s with no problems, IME. If they went bad ater 100 rds, S&W would not stamp them +p.

My 442-2 has never ate anything except +p's. I bought several boxes of Winchester 125gr +p's when I bought the gun and have not fired anything else in it. As of yet, no problems whatsoever to report. As long as I can keep hold of the little sucker, it does it's part.

 

[Spotteddog]

Been firing +P stuff out of a 342PD for 8 or 9 years now. My hand hasn't held up as well as the gun. I figure if a Ti non-Scandium J can handle it, yours should be OK.

The article looks like an edited version of an Evan Marshall article. I can probably find the original if I look hard enough. That being said, I'm not going to pay much attention to anything written by "Anonymous." There's enough garbage floating around the internet, and if someone doesn't want to put their name on it, even if it's a "nom de plume," then I'm not going to give it much credibility.
I've carried a 642 as a issued back-up gun, a 442 as my personal BUG, and now I'll be carrying a 637 9mm conversion. I always carried +P in the 642/442 and never had a problem. I'll limit the 637 to standard pressure 9mm, as it's already appreciably higher the .38 Special +P. I've never worn out a J frame from shooting too much or shooting too powerful ammo; the limiting factor has always been what my hand could bear, not what the gun could take.
