Initial Review - Sterling Arms International (SAI) R9 Mk1, 9mm PCC

[Bartok5]

The secret sauce for inexpensive SIG MCX Folding/Collapsible Buttstocks is Airsoft. I am dead serious. $130 will get you a perfect clone in every regard, indistinguishable from the $300 genuine article. I have both, and aside from the Mounting Screw I honestly cannot tell them apart. The Airsoft MCX Buttstocks lock up tight, and function identically to the real deal. There is not much more to say, other than to note that you can readily purchase the Airsoft version for half the money of a seemingly unobtanium genuine MCX Buttstock. I have fired 700 rounds through my loaner Review R9 using the airsoft Buttstock without incident. It is good to go!

Just do a Google search for "Airsoft SIG MCX Buttstock - Canada" and take it from there. "Airsoft Artisan" offers high-quality versions of the solid metal, fixed-length SIG MCX Buttstock. Otherwise, good quality Folding/Collapsible MCX Buttstocks are avalable from a vareity of manufacturers....

I was thinking a skeletonized minimalist stock like this.

The Airsoft crowd have those. As I mentioned above, "Airsoft Artisan" is the way to go....

2nd this I own multiple.

Airsoft Artisan has stocks of various lengths.

The OEM R9 stock is 240mm long in the fully closed position, which gives a ca. 13" length of pull, which is about right for a PCC.

FYI, these will be on display at the Toronto Sportsmen's Show next week

are these available online anywhere yet?

J.D. may have some backup on his worry about Glock mag reliability in a PCC. According to feedback given ny CMMG to Honest Outlaw on some malfunctions on his initial testing of the latest version of CMMG Banshee:

CMMG said the old Glock mags were most likely worn, causing overinsertion, leading to first round not stripping off mag.

Honest Outlaw had previously tested the newer Staccato that comes Mec-gar metal Glock magazines. I suggested in a comment that he should try those. I'll post if he responds, or does an updated video using the metal Glock magazines.

I’m going to get lambasted for this but I couldn’t locate an Sig MCX folding stock anywhere. I bought one from Andy’s Airsoft in PEI, it shipped fast, and I’ve put it on my R9.

So far so good. It seems really solid.

Why would we lambaste you? I emphatically recommended Airsoft Picatinny SIG-style Folding and collapsing Buttstocks for the R9 earlier in this thread. They are the answer for affordable yet sufficiently sturdy and durable Buttstock options for the R9 and other low-recoiling firearms. The more people try them, the more acceptance there will be for the limited use of practical Airsoft accessories on genuine firearms.

Holy smokes! You had!

I thought I had kept up on the thread but I hadn’t.

Great minds....

Has 3D printed polymers advanced enough that a 9mm PCC printed stock is feasible, or is there still too much flex in the polymers available for a 3D printed stock to work?

If you use the higher strength materials it can be done perfectly well with printing.

The weakness with 3D printing is not the filament, it is the layer bonding. 3D printed things tend to fail along the layer lines.

Printing long, thin parts also runs the risk of warping.

You cannot produce a single 3D printed stock for less time/effort than you can buy an airsoft unit.

All true and all can be dealt with through good design practices and designing for the materials used. The way I would do it is most likely printing end fittings and using extruded aluminum tubes in between the hinge and butt fittings.

You cannot produce a single 3D printed stock for less time/effort than you can buy an airsoft unit.

This is very true and holds for most things. If something is being manufactured on a production basis it is very unlikely you will be able to do it for cheaper/less effort on your own on a one-off basis. At that point it's only worth doing if you can't buy what you want or simply want to tinker and have a project to do.

3D printing is best for custom things that simply cannot be bought. As mentioned above it would be best in concert with other, stronger parts.

TacticalGear4Life on YouTube gives his thoughts after testing the r9:

I have that exact stock I use it on a .22 and it’s not a bad stock. Need to be carful where you buy as some sources are not as good as others

I saw on the Ballistically Speaking video that there now exists an 11" restricted version, any idea when it will hit shelves?
