Reviving this thread to talk about 1913-interface side-folding braces. I am really focused on a Contender application, but I figure this a better place to talk about side-folding 1913-mount braces.
I spent some quality time with Contender parts and the scale this evening. I have a Choate M4 adaptor, which I've been planning to use to install a receiver extension and either Magpul MOE SL-K buttstock or SBA3 brace, depending on what barrel I want to use. I currently do have a Super 16 barrel in .223, which makes it a legal non-SBR. The problem is it all gets heavier than I want it to be. Also, it doesn't fold, so I can't just throw it in a backpack. Yada, yada, all discussed throughout this thread.
I also picked up the Sharps Bros. 3D printed Contender grip, which puts a vertical 1913 interface on the back of the gun, opening up the option of using all those braces.
https://sharpsbros.com/t-c-g1-origin...terface-black/ Didn't really like the grip shape at first, but am thinking it's at least worth working with a little. It's really light.
SSK has mentioned they are also working on something in this arena, but I don't have any more info than that.
I've basically been looking for info and reports on the SB 1913 brace and the Sig PCB. Specific comments from earlier in this thread on those two in these quotes. Not sure why the pics aren't included in the quote, but this post (click to the original to see the pics) really makes me want to stay away from anything that works with a receiver extension, such as the Tailhook Mod1:
Curious whether anybody has experience with the aluminum version of the SB1913? The aluminum weighs a little more, but I've been leaning toward it on the assumption it would be stiffer.
I've seen a statement that the SB1913 brace is an inch longer than the Sig PCB.
I've been looking at both butt stocks and braces. I'm not married to the idea of having it be a braced pistol; I think I could live with it either/or reasonably well. That puts the
Sig Minimalist and
Minimalist-Plus stocks into play (I've found the Minimalist in stock online), as well as the original MCX/MPX Thin Folding Stock, which I've found one retailer web site claiming to still have in stock. I kinda like the simplicity and robustness of all aluminum, small and light. I could stamp a Contender, but don't need to. With a Super 16 barrel, it would come out ~19-20 inches OAL with a folded side folder. The 11-13 oz range for the folder assembly gets me overall where I want to be for the combination.
As noted above, I have contemplated the Tailhook Mod 1. Would need to pair it with a side-folding receiver extension adaptor and RE, which drives the cost up. Gear head has a RE made to place the Tailhook farther out, ~9 inches instead of ~7 of a standard RE, but from what I can tell, they basically have a solid slug of material in the last two inches of the RE, making it quite heavy. One review compared it to a baseball bat. I could throw it in the lathe and bore it out, but it would still have the thickness that I'd like to avoid when folded.
I did find this adaptor for Tailhook to Sig PCB that eliminates the spin,

I guess I'm looking for overall thoughts on:
SB1913 brace and poly vs. aluminum
Sig PCB
Sig and any other side-folding legal rifle stocks of quality
(The Choate side folding Contender stock is not interesting to me.)
