It is always difficult to please everyone, and purists will always come out of the woodwork to point out something...
But there are quite a few TM 1911 variants out there and anyone who games their 1911's would almost certainly want the extra gas capacity.
As for the looks, I rock my KWA PTP with the 32 round mags out the bottom. They stick out an extra inch or so, but the extra gas and bb capacity is what did it for me. Some people will like the extra mag sticking out the bottom looks wise, others won't but it would be great if people had the option at least!
I would say go for it!
But that is easy for me, as I do not have any 1911's and I would not buy these as a result. The only thing I would be concerned about is as long as TM does not have any longer mags in the works themselves...
It would really suck to do all the prototype work and designing only to have TM come out with it a few months later and take a lot of the market share...
I do not think that TM is doing that, nor would they be interested in doing that. The TM Hicapa was out forever and they did not make an extended mag for it until they came out with the extreme full auto version. So I don't think TM will bother making an extended longer mag for the 1911's. It would be more of a niche market I would say.
But then again what the hell do I know! lol
