: Glock 19 Gen3 .177 Caliber BB Gun Air Pistol ...
Great for low cost marksmanship practice, drills, etc. Keeps G19 shooters practicing on same platform. Pays for itself in just one avoided trip to the range Sights don't appear to be replaceable, however comes with standard Glock "combat sights." Price is a bargain. Very, very happy with purchase!
