Hi, folks.
I picked up a threaded barrel for the SIG P320 to use in my SIG M17. The M17 has a Loaded Chamber Indicator that fits in a notch. If I remove the LCI that leaves a gap. So I'd like to get a notch cut in the P320 barrel to fit the LCI.
This picture shows it more clearly than I can describe in words.
It looks like a 4mm x 2mm cut.
Anybody know who I should talk to?
