Nothing special with these firearms.
People use different methods:
- you can shoot right away doing nothing before...
- you can wipe them out from outside (remove original oil)
- you can field strip, clean, lube then shoot
- you can completely disassemble, clean, lube reassemble then shoot
and... what I'm doing:
- unbox, drown in Isopropyl Alcohol for 30 minutes; completely disassemble, clean, lube reassemble then shoot
I believe all methods give the same result... however I don't trust anyone and that's the reason I want to be 100% sure of firearm condition before I shoot it.
The goal is you need to be sure it is lubed properly.
