Galco APO holster for the Glock G21

Galco Gunleather is now offering its leather APO holster to fit the Glock G21, Glock’s original .45 ACP duty-size pistol that spans back to the Glock third generation. 

The Galco Gunleather APO is a field belt holster designed for outdoor activities like hunting, hiking, riding, camping or any other backcountry adventures and can be worn either crossdraw or strongside. Galco APO holsters also come with an adjustable tensioning screw near the trigger-guard area and a thumb break to help hold the pistol in place during vigorous outdoor activities. The body of the Galco APO holster is made from a selection of tough, unlined, premium steerhide that holds up to rough field use over time. 

For a quality fit, these holsters are hand molded during construction to ensure they fit their respective handguns like gloves. Besides holster performance, the hand molding also adds another degree of aesthetics with sharper and more defined lines. 

Galco APO holsters are available in either black or tan leathers, and are designed to fit belts measuring up to 1.75 inches.   

Galco APO Features

  • Premium steerhide construction
  • Low ride strongside or crossdraw carry
  • Retention strap with glove-friendly tab
  • Tension unit adjustment
  • Detailed hand molding
  • Fits belts up to 1.75 inches
  • Black or tan finish
  • MSRP: $148

The Glock 21 is a 13+1 round, .45 ACP duty pistol based on Glock’s well known tilting delayed blowback action and its famous “safe-action” striker trigger assembly. Because it must accommodate the larger .45 ACP cartridge, the Glock 21’s grip, frame and slide are wider and its magazine capacity is less than its 9 mm counterpart.
