My 24 inch 1301 comp pro came with a 1 inch spacer. I’m an average size guy and it made it way too long to shoot comfortably. I removed the spacer and reused the screws no problem. The gun is now much more comfortable to use.
The gun runs 100% and I love it. I’m trying to figure out 922 compliance parts so I can put a tube extension on it.
It’s looking like the briley trigger may be the only easy way but it’s $$$.
