With full auto GBBs, you would need to require alot of mags..
Everyone who owned a TM Hicapa has been very pleased, and a very accurate pistol right out of the box. You cannot go wrong with a TM.
There are nice Kimber slides and such for your 1911 taste.
TM Hicapas comes with metal frame, ABS plastic grip, and plastic slide. The upgrade for metal slides are everywhere. If you plan to have your own custom built Hicapa, talk to Illusion, he will build a Hicapa for you if you got the cash.
Lots of parts for both Hicapa and Glock too.
