First things first, I know there are plenty of Glock forums I could ask this on. I don't belong to them and wouldn't know if I could trust any responses. Not so here. Second, I may reach out to the manufacturer, but I bought this used so they really don't owe me tech support.
And so, I have this Wilson Combat drop in barrel (Item #381) that fits a Glock 21, of which I have 2 (both gen 3, 1 a standard G21 and the other a G21 short frame). I bought it used/unfired.
The short version is this: with the barrel in place and seated properly, the slide sits .020" further back in relation to the frame on the SF version and .016 further back on the standard version. Empty chamber or dummy round, doesn't make a difference. The barrel does not bind on the slide. The question - is this to be expected, normal, acceptable?
If it's not that simple, more details follow:
-------------longer version-----------------
In both guns, the barrel fits fine, the action cycles by hand, the striker cocks and the trigger releases it. I measured the distance from the rear slide cover to the trigger housing, at the notch on the left where the trigger housing is visible. The attached pic shows the area I took measurements. Measurement was by electronic caliper.
Glock 21 Standard:
Stock barrel - measured .044" (from the face of the rear cover to the face of the trigger housing)
Wilson barrel - measured .060" (from the face of the rear cover to the face of the trigger housing)
Glock 21 SF
Stock barrel - measured .034" (from the face of the rear cover to the face of the trigger housing)
Wilson barrel - measured .054" (from the face of the rear cover to the face of the trigger housing)
The Wilson barrel fits into the slide slightly tighter than the stock barrel but does have some clearance.
With the guns assembled, either cocked or decocked, the barrel will push down slightly with my thumb, as illustrated in the attached picture. Both stock and Wilson barrel behave exactly alike.
In short, both guns act exactly the same way with either barrel installed and with or without a dummy round chambered.
I'll appreciate anyone's thoughts or experiences.
