Apr 24, 2018· (Most frame cracking for 6000/7000 and scandium frames is in the heat affect zone of the welds). So by using scandium/aluminium the manufacturer can ride a finer line between a sucessful welded frames and a bunch of broken frames.

Sep 07, 2010· All of that said, I doubt I'm going to be able to wear out my 4040PD or my M&P 340 any time soon. I actually bought the M&P 340 as sort of an 'improved' 642, meaning I wanted to subject it to the brunt of my training/practice regimen with the J-frames because of its stronger Scandium aluminum alloy frame.

Nov 11, 2017· Scandium frame wear. Hi Folks I am looking at buying a Smith and Wesson 1911 e series scandium frame. But I have not seen one in person. I am wondering as a shooter pistol how is the wear and will hold up. I will run this for IDPA once a month as it will replace daily carry 5 inch. So if anybody can share their experience thanks.

Aug 17, 2013· I've got a couple small nicks on my carry scandium frame revolver. Was wondering if anyone has touched up one of these before. My friend recommended getting a glass paint pen from a crafts store and trying it out, I'm nervous about trying that out though

Jun 18, 2019· When you mention Scandium frames, many people think of the 340 PD or the 329 PD and the potentially punishing recoil from the disparity of the overall weight to the chambering, but Scandium is also used in guns like the M&P R8, the TRR8, and the discontinued Nightguard series.

Jul 21, 2008· I have yet to hear of a S&W with scandium frame failing due to metal fatigue and there are thousands of them out there. On the other hand, I have only heard of a few non-scandium aluminum frames cracking on Lightweight Colt Commanders over the years. Unless you put 5000+ rounds down range per year, I don't think you need to worry about it.

They have not necessarily used scandium ally alloy to make a lighter frame – if the tube profiles remained similar to whatever 7005 (or whatever) frame they were basing it on, it could be stronger.

A "scandium" frame is basically and Alu frame with some trace scandium. Alu frames themselves are not especially popular now, especially at the mid to high end where a "scandium frame ...

Feb 12, 2011· I have a 327 M&P R8. 357 N frame made of Scandium. Easy to shoot, very durable. S&W techs tell me this will wear as well or better than steel, even with full power 357s. carguy2244, Feb 6, 2011. carguy2244, Feb 6, 2011. Feb 6, 2011 #7 . halfmoonclip. Messages: 4,120 Likes Received:

Mar 01, 2007· Even though in more recent years, the alloy frames appear to be a non-issue, one 1911 producer took a good idea and made it even better. Last year Smith & Wesson introduced its SW1911PD pistols that feature scandium frames. Scandium, discovered in the late 1800s, is as costly as gold to mine and almost as rare.

Ridley Supercross Frame and Fork. Light 1280 grams scandium alloy frame with carbon seatstays and awesome carbon 4ZA Python fork. RIDLEY size 50 cm which fits like a 53 for other manufacturers. I am 5'8" and ran a 80 mm stem. Will fit riders 5'5" to 5'10" depending on stem size and riding preference.

Dec 16, 2008· Both rumors could be true, if the frames of the scandium revolvers are mostly aluminum. Steel stretches, aluminum doesn't. Because of that, aluminum will develop fatigue cracks more quickly than steel, and can suffer catastrophic failure.

May 26, 2010· Shooting standard pressure loads will keep frame stretch to a minimum. I've seen old Airweights that have always shot standard pressure loads and the frames were still within acceptable tolerances. If you shoot all +P ammo, you can bet on eventually stretching the frame. As to the hole wear, if the gun is kept clean the hole won't wear as ...

Jul 24, 2015· Scandium is used in trace amounts in the Aluminum alloy. What S&W has is a Patent for a process on how the Scandium is incorporated during the formation of the Aluminum alloy or "how the cake is baked". Other makers may well use Scandium and a …

Jan 01, 2020· When I feel the need, I wear the 627-5 in a shoulder holster to take the weight, girth, and length of the big N-Frame off my hip. I also carry a S&W Model 66 "snubbie" in a Galco high-ride belt holster in lieu of the N-Frame. The scandium J-Frame then goes into a pocket holster on the opposite side as the Model 66.

Sep 23, 2020· A friend has a new revolver, a Model 360 I think. It's a lightweight, scandium frame 5-shot .357 Magnum revolver. He wants to reload for it, and he thinks he wants to shoot large quantities of full magnum loads in it. Given the historical durability issues with K-frame S&W revolver and .357 magnum ammo, I have to wonder how these little alloy J-frames can hold up.

Oct 13, 2014· I prefer the aluminum frame 1911 mostly because of the weight loss in the material itself. but if considering an aluminum frame firearm no matter if its pistol or long gun. the alloy is important. 7075 is the preferred alloy. its tensile strength is much higher than the more common 6061 alloy. this is very evident in machining the material. the 7075 cuts more like steel than aluminum. its much ...

Enter now, the S&W 340 PD revolver, the maximum expression of the Centennial family, chambered in .357 Magnum and weighing only 320 grams, thanks to its Scandium light alloy frame and the titanium cylinder: needless to say, its lightness tempted us and we bought a sample years ago.
