Glock has been building striker-fired, polymer-framed pistols since 1982. Few parts, hard to break, and for a lot of shooters the Gen5 19 is still the default answer to the question of what to carry.
We are a licensed dealer and Glock is one of the lines we keep on the floor. The case is the point. Come in, pick one up, and see how it sits in your hand before you spend the money on it.
If it is your first pistol, ask at the counter. That conversation is free and it is worth more than any spec sheet.
