Key Notes

  • Glock 47 is a standard-size 9mm model with a slightly redesigned lower receiver compared to the G17. 
  • Glock 48 is a compact model with a 4.17″ barrel, larger than the G19, offering improved balance and recoil control. 
  • Glock 49 is not an official model; it’s a misnomer sometimes used for a 19 lower with a 17 slide (not factory-produced). 
  • Generation differences (Gen 1 to Gen 5) affect grip texture, backstrap modularity, slide stop, and barrel accuracy (Gen 5 features Marksman Barrels and nDLC coating).
