Best .357 Sig carbine ideas (even 9mm & .40 S&W)
I was reading a post from December about AR-15 .357 Sig carbines.
The topic was AR-15 platforms, so I started this thread to avoid derailing that post. An AR-15 .357 Sig is a fun idea and all, but given what you get, and for the price, I think the following are better concepts:
What I like best about the sub-2000 is how easy it would be to store. I have been told you can order a .357 Sig version of the sub-2000. In addition there you can request versions that will accept Glock, S&W, Beretta, and SIG Mags (so you can match the carbine to your pistol's mag).

Another option for Glock owners would be the replacement upper called Glock CCU.
I'm not sure about performance and quality differences between the sub-2000 and the CCU. However I think I favor the sub-2000 as you get a firearm (using the spare mags you already have) without having to lose a pistol (Glock lower) in the process. I'm not sold on either, but something I think about.
