I would love to see a cleaning, lube maintenance video based upon round count with information on expected life span and part replacement schedule. Thank you for you for great content!
I don’t know how many rounds you shoot on weekly basis or the type of ammo you use, but in the 2 years and 4000+ rounds I’ve shot the MR in competition and with all cheapest ammo I could find, the striker channel itself looks brand new still with none existent friction. I use a dry q-tip to wipe the channel every few range trips and so far I’ve had zero extraction/slide related issues. If you got the dot zero’d in properly it wouldn’t take more than 9 rounds to re-zero once you’ve reassembled the optic. Just my two cents
This helped a lot. I purchased a MR920 w/ optic cut last weekend. I was taking it apart to clean it and I thought I was missing the extractor assembly. I was about to give customer support a call, but I saw this video first.
Great video, Trevor, and a really good solution to make a more robust mounting system for the optic. I'm a mechanical engineer and fellow firearms enthusiast, and I approve this message!
Glad I kept watching after the first little bit, was trying to skip around and thought I was losing my mind shooting without an extractor plunger until I took off my red dot and saw the spring 😂
I love my MR920 as well. Thanks for putting this up, it's nice to see how it's done. I was going to be reaching out to Richie with this question soon, but this saves us both some time. It's comforting to know that spring has been designed to exactly replicate the stock Glock one. A couple of thoughts:based on my conversation with Ritchie, it's probably useful to mention that you want Loctite 243 not the more common 242. It makes much less of a mess, and it eliminates the slight possibility of excess running down into the inner workings of the slide and causing malfunctions. Also, what's the punch size for that smaller punch that fits through the pass-throgh hole for removing the retaining pin on the Extractor assembly? Keep up the great work guys!
i got the 920 a few days ago with holosun 507c x2 mines didn't come with an optic cover plate did this happen to anyone else or is it not suppose to come with one
I live in Plano, and it’s so frustrating being so close to your facility, but can’t get my hands on one of these! Hopefully Rifle Gear will be in stock soon so I can get mine!!!
What is the max round count yall have put on a MR920? Just curious about your testing process. What do yall say to make a customer confident that the MR920 is "just as reliable" as a new Gen5? Thank you sir!
Which line of the handguns uses the glock style dual spring system? Im thinking of getting one but i have a preference of the dual spring system. Are there any model that has ambi slide catch/release? Your website does not list a lot of info about your handguns
The bevel at the rear of the slide is a curious decision, considering how thin the rear-sight dovetail became as a result. That looks like very little metal holding the rear sight in place...
Matthew, nice observation! When we made that decision we did not take it lightly. Our testing consisted of machining the back off the slide at the same angle but much “deeper” into the slide leaving exactly 50% of the metal that the actual production slide has. We installed the rear sight and put it on a gun. We then bolted a half inch steel plate to a work bench and lined up our assembly team. They racked the slide at max effort 500 times on the edge of the plate, often with their full body weight behind it. You should have seen what this slide looked like. Mangled! The rear sight did not move in the slightest. We then went to the drop test fixture and did multiple drops on concrete landing directly on the rear sight. Even we were surprised that the notch did not loosen. To be totally honest, we finally went out to the parking lot and chucked the gun 20 or so feet in the air. On the second drop the rear sight notch did loosen up. With that said, we are very satisfied that it will stand up to any reasonable abuse. I’ll add that the plastic sights you often see on stock guns would have been sheared off or totally smashed far earlier in such a test. We feel confident that there is plenty of material, because again, all of this happened at 50% the true material thickness. Thanks again for the comment. You’ve got a keen eye.
@@ShadowSystemsCorp Thanks for the quick and thorough response. I'm considering an MR920 to replace my one and only pistol, an H&K VP9, which doesn't suit me. I've been impressed with the reviews so far and look forward to handling one at a local store at some point.
Paid a lot money for the CR920. Too bad Shadow Systems decided adding a 20 cent Allen wrench was too much. What a pain in the ass finding the correct Allen wrench to loosen it. Unreal....
Hey Trevor, will the MR920L gun mat in this video be available on the website? Also curious as to what comp would be recommended for a non-threaded barrel. Thanks!!
the CR920 optic safety plunger installation is extremely difficult. should come with a tool to perform installation and removal. a gun is useless if it cannot be cleaned regularly and easily.
Hello! Definitely not. The removal of the extractor assembly is armorer level maintenance that is likely never done for the vast majority of pistols. It is really only needed in the case of a component replacement which is exceedingly rare. The firing pin assembly is removable any time should the channel need to be cleaned (no need to remove the optic.). Hope this info is helpful.
I think Covid has screwed over manufacturers and suppliers. Don't expect parts or handguns until maybe in a few months at least. August at the very earliest I'd bet.
Are there any differences between the mr920 on your website and the mr920 that john lovell is selling on sportsmansguide.com?? Other than the fact that it comes with an optic ?
I feel bad for the suckers that actually buy this crap. It’s just a modified Glock, why not build one out yourself? The cost of one of these shadow corp is literally THREE OEM Glocks. Even if you built one out yourself, the price is still fraction of one shadow corp
Wish like hell id seen this video about an hour and an Email ago. I removed my 920 backplate to check the channel liner and everything over an odd noise. Seen the open hole and thought mine was missing the plunger and spring. I remember that odd cut and spring when I mounted the 507 on it. Sent an email like a moron worried my piston was missing a $10 part. At least now Im not waiting days to hear back and get to fire the piston right away. In my defense I'm used to G platforms, just not big improvements on them lol.
Hey! What a pain, sorry for the trouble. Yes, if you remove the back plate, the extractor depressor plunger will not come out as it is retained further in the slide by the tensioning pin. At least you aren't missing any parts! Trevor
@@ShadowSystemsCorp Thank you for the reply. After all of this, I finally got to the range sunday. Fired 5 rounds myself through 5 different mags, then let the armorer there fire it. My extractor indeed has a problem. Its stuck out basically. Maybe that's why it felt odd to me. Goes into battery no issue but will NOT extract the round in chamber. We pulled the gun down and the extractor hangs open in the slide. Im waiting today until the shop where I bought it can see what they can do for me before I call. Ive watched several of your videos now and your custom service level is just unheard of today. I hate that I might have to use it, but ill be calling in next day or two if I cant get problem fixed locally. The 5 rounds I did get to fire made me even more excited to get this thing running again.
@@ShadowSystemsCorp Please dont take it that I'm here trash talking my favorite firearm Ive ever owned. Im only waiting to see what local shop says 1st. Your reputation is spotless as far as any review Ive ever seen.

The pistols that have the optic installed do not ship with the optic cover plate. We found that most folks who purchased the optic installed version did not need or want the optic cover plate. If you do want one, they are available on our site.
@@RetiredBadge not sure if I will sell it. We are always adding to the collection. And this is def on the list. The optic mount set up is awesome from the out side looking in. Hoping to join the club soon.
I completely understand. Picking a carry gun is like picking a wife. Ha! Only you can do it. The big sale for me was having the back strap that gave me the point of aim of my 1911’s. The optics and looks overall wasn’t a hurt either. 👍
Well piss I came to this video trying to figure out how the hell to get replace my safety plunger spring with a lighter competition one. Not removing my optic for this crap.

So you have to remove your optic and re-zero it every time you clean your slide. I wish I’d known this before buying this gun because I wouldn’t have.
I don’t know how many rounds you shoot on weekly basis or the type of ammo you use, but in the 2 years and 4000+ rounds I’ve shot the MR in competition and with all cheapest ammo I could find, the striker channel itself looks brand new still with none existent friction.

This explains a lot cause i thought i lost my extractor spring somehow
Same

I love your videos, bloody hands. Not like when we were in our 20's huh! Thank you sir for everything and my family's safety.
Just ordered a 920. I have been watching everything on it. Thank you for the video.
Let us know how you like it bud

Any plans on a full size or 17 & 34 slides with your ingenious rds mounting system? Not really into compacts.
Just got my and love it already! Nice video
so in order to clean the extractor and it's channel you must remove your dot ?
Paid a lot money for the CR920. Too bad Shadow Systems decided adding a 20 cent Allen wrench was too much.
What a pain in the ass finding the correct Allen wrench to loosen it.
Unreal....
So if an optic is mounted does it have to be removed to get the plunger pin out?
Of course.
Hey Trevor, will the MR920L gun mat in this video be available on the website? Also curious as to what comp would be recommended for a non-threaded barrel. Thanks!!
Thank you.
I was wondering if you guys could do a video on the adjustable spring that comes on your guns?
Uhhh you have to take the optic off just to clean the extractor? Wtf?
I am having problems with failure to extract rounds in my CR920 I think this is the culprit.
Is it recommended to clean and oil all those little pieces such as the extractor firing pin the spring etc?
Are the internal parts of the MR920 frame compatible with the oem Gen 4 Glock 19 parts? Particularly the connector.
Yes, with the exception of the extractor depressor plunger assembly. We use TTI connectors.
ShadowSystemsCorp thanks for the response. I love my MR920!
the CR920 optic safety plunger installation is extremely difficult. should come with a tool to perform installation and removal. a gun is useless if it cannot be cleaned regularly and easily.
Can you mount a Holosun 509T?
Nice informative video.
Does anyone have an MR920 compensator suggestion?
Griffin micro carry comp
What is patent pending? Like they don't have it yet?
Thanks, ordered!
is that front iron built in? can it be adjusted/removed?
So you have to take the RD Optic is the only downside
So are you telling me I have e to remove my optic and re zero everytime I clean my gun?????
Hello! Definitely not. The removal of the extractor assembly is armorer level maintenance that is likely never done for the vast majority of pistols. It is really only needed in the case of a component replacement which is exceedingly rare.

Are the extractor spring and plunger the same on the combat without optic cut versus the optic cut? (On the MR920)
No. The extractor depressor plunger assembly is shortened on the optic cut versions.
@@ShadowSystemsCorp so I’m guessing that means I can’t send in my combat slide for an optic cut?
No, the optic cut cannot be added after production. Sorry
When can we buy the new MR920 slides as an upgrade?
I think Covid has screwed over manufacturers and suppliers. Don't expect parts or handguns until maybe in a few months at least. August at the very earliest I'd bet.
is the rear slide cover compatible with the tau development group striker control device (SCD)?
No it is not.
@@ShadowSystemsCorp thanks for your reply. seems like a well engineered and developed gun. great job
