My over 1 year old SIG P365 with the Nitron finish has worn extremely well. Meanwhile....my $1500 SIG P229 Legion RX with the 'Legion exclusive' PVD finish has worn through to bare metal from holstering. I think I could apply a more durable finish from a spray can. When I contacted SIG, they just shrugged and said I could send in and pay for it to have a more durable finish applied in their Custom Shop. Good luck and let us know. -YMMV
