Glock 17 - 3rd Generation

The Glock 17 is the most important pistol design of the last 50 years.

The Glock 17 3rd Generation.

The Glock 17, adopted by the Austrian military in 1982 was the first successful polymer pistol.  Though the frame and internal parts were steel, the frame was an advanced polymer (Plastic).  This saved weight, while increasing magazine capacity and though slightly smaller and significantly lighter than the Beretta 92 and Sig P226, the Glock was able to hold 2 more rounds of ammo.  Importantly the Polymer construction of the slide significantly reduced manufacturing costs, making the Glock cheaper than typical 9mm service pistols.  Though there are no apparent safeties, the gun has a drop safety, a firing pin safety, and a trigger safety, to ensure it only fires when the trigger is pulled.  

The Glock 17 was also designed for extreme reliability with fewer moving parts and fewer total parts than the typical pistol.  In fact the Glock 17 3rd Generation has only 36 parts, including the 5 magazine parts.  A Beretta 92, a reliable pistol when using good magazines, has almost double the parts count at 69 parts, including its 5 magazine parts.  The Glock’s extensive use of polymers and advanced coatings on the metal parts also reduces the chance of corrosion impacting reliability. 

The good handling characteristics and accuracy, combined with incredible reliability and low cost has made various versions of Glock handguns the most widely issued police handgun in the world.  It is also, also the general issue sidearm for several armed forces including:  Austria, Finland, France, Israel, Malaysia, the Netherlands, Norway, Poland, Romania, Sweden, and Switzerland, and the United Kingdom.  It also issue to select units of several other militaries including the United States.

The Glock spawned a revolution in pistol design and a striker fired pistol with a polymer frame and steel slide is considered the template for a modern handgun design.  The Beretta APX series, CZ P-10 series, FN 509 series, H&K VP9 series, SIG 320/M17 series, Springfield XD series, S&W Sigma Series, and Taurus Millennium Series and Walther PPQ/Q4 all follow this design pattern, established by the Glock in the 1980s.  

Glock itself has an entire family of weapons spawned from the G17 that function exactly the same in 5 different generations.  The 1st generation, from 1982, had a slide without finger grooves or checkering and was the one adopted by the Austrian Armed Forces.  The 2nd generation, introduced in 1988, added checkering to the front and back of the grip.  The 3rd generation, introduced in 1998, finger grooves and a rail system for mounting lights.  However, Glock rails are not M1913 standard, though many accessories will still fit or come with adaptors to make them fit.  The 4th generation, introduced in 2010, added interchangeable backstops to adjust the grip size.  The 5th generation, introduced in 2017, removed the finger grooves and added several other features, like front slide serrations.   Though parts are generally interchangeable among the first 4 generations, the same is not true with the 5th generation.

Glocks have been offered in the following calibers:  .380” ACP, 9mm, .40’ S&W, .357 SIG, .45 ACP, .45 GAP, and 10mm.  Glock sizes include:  long-slide competition, full-size, compact, and sub-compact.  Currently, in 9mm alone Glock offers; the Full Size 17, Compact 19, Sub-compact 26, and full-size competition 34, and long-slide competition 17L.  There are also single stack Glocks now, but they are significantly different from the double-stack service pistols.
