At a recent gun show I saw a holster advertised as the "ultimate conceal carry holster". It slips into pants behind front pocket and is attached to cell phone holster. On need to present, one pulls up on cell phone holster and up comes the weapon ready to grip and present. On first inspection this looks very good. Extreme concealability, quick presentation, comfortable (I tried one on), no need for special belt, and one size fits all handguns. I have not found much feedback searching through the threads here and am surprised it is not more popular. Carry for me must be well concealled and my choice is J frame in front pants pocket. I'd prefer to have more rounds available but IW is too risky in getting noticed. Walther PPS looks like a possible weapon choice, but if holster gives flexibility and comfort, it appears the best option. Please comments on the pros and cons of this holster.
