Metalworks 101….take any piece of metal and flex it back and forth over and over. What happens? It weakens and eventually will break. Often times depending on how much it’s bent, it will heat up. That heat lines up the molecular structure in metal and weakens it even faster. Now, take spring steel that has been formed into a coil spring. Now compress it and leave it there. Does the metal weaken? Not just from sitting compressed. Flexing weakens metal. Not compressing it. Continually loading and unloading magazines weakens the springs much much faster. So load up your mags and leave them alone. You’ll be dead before any significant weakening of the springs happen. Class dismissed.
@@albundy7459these are not milsurp mag. Those magazines are also only worn out because they are left to rot. Pitting and rusting is completely different from leaving a loaded magazine w compressed spring
As a new gun owner (of a MR920P) , this is really great information as I've been wondering about the durability of loaded magazines. Thanks for covering this topic!
I carried a 5 different semi automatic pistols as an LEO for thirty years. I never unloaded my mags unless I shot them empty in training. I also never had a magazine fail when firing. I have seen older two piece Sig Sauer mags split along the welded seam along the back. .
Great info….. with so many shooters utilizing dry-fire to minimize limited or expensive ammunition I’m assuming the 5,000 round count for recoil springs is still appropriate? I typically dry-fire 500-1,000 laser shots per week between 3-4 guns and was wondering if racking the slide back to activate the trigger is wearing down the recoil springs as hard as shooting range ammunition each week? I typically run a 10-1 ration of dry-fire to actual range ammunition for recoil management and training drills. Thanks - enjoy your videos and your guns🤠
Speaking of spring. A spring broke on my CR920P slide release lever and Shadow Systems sent me a replacement part that I installed. I noticed that I can now close the slide with my right hand thumb - something I couldn't do with the one that shipped with the gun. I asked a question about it to SS Tech support and wanted to know if the part dimensions changed. Their response was to sent them a picture of the broken and new part. WTF? SS Tech Support should have a part change history at their finger tips! I am asking because I also have a CR920 that I would replace the Slide Release Lever on if it would allow me close the slide with my thumb. I love the guns, they require more cleaning than Glocks, but shoot a lot better.
Are you really sure you can’t pull out (say non captured recoil) springs? I’ve always heard you shouldn’t, but I’ve done it a number of times and it seems to work very well, at least for a while. I’d like to see some testing or at least a metallurgist speak to this.
Trevor, Next tuesday can you talk about what happened with MCK and shadow system collab, it seems like palmetto arms got to make their MCK for the dagger faster. Is it over, cuz if so their website still has it listed
I do know for a fact from practice and training that my glock mags last years and the pmags for pistols fail often. Pmag rifle mags are good just not their pistol mags
Why is this even a topic of discussion? I don’t read nor hear about anybody questioning this issue any longer either. The myth was dispelled 20 fricking years ago! It’s fine to keep magazines loaded FOREVER! But I guess you new kids don’t know this siht and feel compelled to bring up a worthless topic from the grave.
It's a topic for discussion because there are still uninformed people saying inaccurate stuff, so it's not trivial to find the answers and recognize them
@@tannermeade Well it’s like watching the twentieth remake of a movie that was made 70 years ago…. When Hollywood can’t produce new content, they just remake the original. …a lot of that happens on TH-cam as well.

Got my cr920p yesterday. Love the gun and also the time you take putting out videos like this. Thanks from Michigan.
Yes…. Now you don’t have to watch the video. Have a great day 🫡
You must be fun at parties. 🤧
thank you :D not every hero wears cape :D
@@hlclc1234I heard he is. He’s a legend to me!
Not necessarily. Springs are metal and susceptible to corrosion. Milsurp magazines are notorious for pitting and rust in springs.

Thanks Magnum PI for the info!
immediately had the same thought. The theme is playing in my mind right now.
😂😂😂😂😂😂😂😂😂😂😂
Lol, nail it!!
The other guy looks like an Asian version of Sgt.Carter from Gomer Pyle.
Someone get him a Tiger's ball cap.
I just got the XRP and it's amazing. Thank You for designing such a beautiful pistol.
Subjective, i think the guns ugly.

Carried loaded magazines on my sam brown for 20 years. Never a problem.
Awesome stuff thanks guys! Still holding off on a 10mm with hopes yall release one some day..
Does dry fire contribute to the 5000 round suggested replacement schedule for recoil springs?
Shadow systems, love your work. The 920L elite is my daily carry and love it…it has shelved all my other carry guns.
Hoping you guys come out with a double stack 1911/2011 in the future… I’m over 100% polymer frames.

Yes I have mags that have been loaded for more than 20 years and they work just fine.
I don't see anywhere on the Shadow Systems store where magazine springs are sold. Do we have to buy a new magazine each time?
Can we please get a video about optic options regarding the Mr920P & Xr920P please. I just purchased one and I’m looking to get a Acro P-2
When do you all plan on making something like PSA with their 15 round micro? I would love to see a Shadow Systems hit this part of the market.

Sure wish I could score an Xr920p and a couple of shadow system stripped frames Trevor
Nice tips, gentlemen. Happy taco Tuesday to everyone at shadow systems

We’ve never looked into doing a micro conversion kit, if that’s what you’re talking about?
Yes, you can keep a magazines loaded for years and have zero issues.
Good info. Thanks!
I do know for a fact from practice and training that my glock mags last years and the pmags for pistols fail often. Pmag rifle mags are good just not their pistol mags
Technical Tuesday: Can I leave magazines loaded?
They are no good to you unloaded. The only thing that wears mag springs out is usage and wear.
Lot of words. 1 word yes.
Love you guys! SS rocks.
Come on man !!!! ..... 😵💫
Are y’all making magazines now? Why else talk about it right? Also - for the love of God tell me that stache and shirt are part of yesterdays novelty
