welcome to THR.
really need a little more info on what you want, and what you want to achieve with the pistol, before we start blasting off answers. Because what will happen is that we will give answers, and then the original poster will be like no no i forgot to mention that I don't want that, and then you will get more answers, and it will go on and on for no telling how long. and we will get no where. please set some requirements. price, capacity, dao, da/sa ,safety or no etc.
now i will go on what little knowledge of what you want. just a few. I can expand on any of them that you find enteresting.
