Carrying a 1911 daily for a number of years now. I have about 50 mags laying around, mostly Wilson 47D's with some Nighthawks (blue and stainless), Wilson ETM's, CobraMag's and a couple DW's.
I prefer the Wilson 47D's with the slim steel basepad for my Commanders and bobtails. You can order the basepads for around $5 as an afterthought. For my full size guns I like the same since I don't run magwells except on my Benny Hill that has it built in. On a magwell gun, I like the ETM or even the blue Nighthawk mags, but mostly for competition, the range or a class.
The only advantage I see in the ETM, CobraMag, blue Nighthawk mag - is that it seats a little easier than a 47D, but I slam them in and have never once had an issue. That and if you get a stuck mag, it's easier to rip out with the wider basepad.
I might add the VBOB (not the CBOB) is worth every bit of it's cost, if you'd ever actually pay that anywhere. I say that carrying a Nighthawk daily, another two on order and probably another one or two after that this year. It's a very nice gun and I've owned 5 Kimbers (all are gone), 2 Springfields, 2 other customs, Wilson CQB, Brown Executive Carry, Nighthawk Talon II (with a custom PDP and a Predator on the way) a few old Colts for the heck of it and from my Dad, etc. The VBOB is a very nice gun for less than half of the $2,950 of my Talon and $3,500+ for the PDP and Predator.....but I have to say that even though I'm not getting twice the gun, I love Nighthawk!
Here's a quick review I did on the VBOB - http://www.defensivecarry.com/vbulle...son-brown.html
