Synchronizor can you chime in I was also looking into the GG&G magazine extension (New model). Woul like a good review on these two.

I haven't used either extension, and I haven't heard enough about them to really make a recommendation. I'd love the opportunity to evaluate more magazine extensions, the S&J extensions especially are at the top of my list, but there's nothing currently in the works. Best I could do right now is help you interpret the sales descriptions for each kit, and compare the different features.

So, it's been awhile, but I recently completed a review of the S&J MK II +2 extension kit. Since this is the thread that got that project started, I figured I should update it. You can read all the details there, but long story short, the S&J MK II extensions are really good. I haven't had any personal experience with the GG&G extension to make a comparison, but the S&J has set the bar pretty high.

$90! Ay carumba that's almost half what I paid for the gun

Yeah, they're not cheap. If you're building on a budget, I'd probably point you toward something like the Wilson Combat +2 instead. But if you have the money to spend and want to step things up, the S&J kit is really nice, and in my opinion has enough refinement and extra features to justify its premium price tag.

Personally I love the Remington extension. The bayonet cap doesn't bother me and it comes with a barrel clamp. Best yet cost around $40!!!

$40 is a pretty good deal, I'm used to seeing the factory extension kits at $50 - $75 street price.

The Remington extensions are good, but the single-piece S&J +2 has a lot more usable space in the tube (it can easily be a +3 with typical 2.75" shells) and it doesn't need a bracket to stay in place under recoil. The Remington +2 wasn't designed for maximum capacity; it has room for two more normal fold-crimped 2.75" shells (which, to be fair, is what the original military users were shooting), but with many 3" shells and even some unusually-long 2.75" shells, it's effectively a +1. And while the reinforcing bracket helps strengthen the extension and has a nice anti-slide design, it can complicate take-down/reassembly and is picky about what barrel it's used with. The factory extensions are nice for a dedicated fighting gun with a standard-profile barrel, especially if you want the modularity and easy repair of a two-piece system, but I reconfigure my gun a lot, and I really like the convenience of a single-piece. Having 7 rounds of buckshot under an 18.5" barrel for bedside duty is pretty nifty, too.
