Good dayall.

Am considering a shoulder rig for carrying a P365. I have seen where folks have stated that a SIG P365 will fit perfectly in a Galco shoulder holster made for the GLOCK 42, even with a laser or light attached.
What I would like to know is...
will the P365 be a little bit loose WITHOUT a laser or light attached?

I am leaning towards a shoulder rig due to the fact that I have Lumbar Sclerosis and a bothersome rotary cuff ailment (old injury ) that restrict IWB carry.
Any help here would be greatly appreciated.

Thank you.
