Fourged In-line 7 Barrel Porting
If you are looking to get your Sig barrel ported and don’t want a long turnaround time at a reasonable price, you might want to look into Fourged Group. I had them expand the top window on my slide and do their in-line 7 barrel porting. It only took them a couple of weeks and they did a great job. I was also pleasantly surprised to find that the barrel ports also matched up with my P320 ProCut and my Norsso Reptile slides.
Shout out to u/WalkThePlankCustoms for the great work and customer service!!
