Update on the Radian barrel and compensator kit we got for the grandson's Glock clone.
Installing the barrel and compensator was super easy. Bare in mind that his pistol is a 3rd Gen M19 with a full ZEV SOCOM kit, slide, barrel and modified frame though the action parts are OEM.
Took it out to the range and after the pistol started heating up, 20+ shots, the action started to stick and eventually wouldn't go into full battery. We brought it home, took it apart, and figured out that the barrel and compensator were contacting the slide at the front edge of the ejection port and just below the front sight so we took off about .010" of material off at those points.
Afterward we took it out to the range again and it worked perfectly with no additional evidence of contact. On a stock Glock I don't think any clearance work would be needed.
After we got the sticking problem resolved and were actually able to run a couple 100 rounds through the pistol the barrel and compensator combo worked amazingly well to reduce felt recoil and muzzle jump resulting in greatly improved accuracy and shot groups for the grandson.
He did notice that the pistol heats up quicker and more when using the compensator but not horribly so and he figures that the benefits are worth the extra heat.
The compensator definitely changes the look of the pistol too.
