Glock's compact 40 S&W equivalent of the GLOCK 19 Gen4 puts controllable power into an ideally-sized package-substantial enough for police patrol small enough for discreet and comfortable all-day concealed carry. It is the top choice for professionals who work undercover. The Modular back strap system makes it possible to instantly customize its grip to accommodate any hand size. The reversible magazine catch makes it ideal for left and right-handed shooters.
