So what solvent would be safe for the whole gun looking for something that isn't gonna damage the base/grip as is a synthetic material

I've been told to oil inside barrel and to not been told not to have any where it will get on to bullets

I have carbon starting to build on on the feed ramp as well will using a copper/brass brush damage the ramp barrel as of right now I use a nylon barrel brush and a nylon double ended scrubber

I oil friction points on slide and base and also on barrel

Still need to this trying to find details do and don'ts

Been told not to get solvent/oil in the firing pin as well why is this and how often should you do a whole break down to clean all the internals

I generally field strip after every range day in between 100-300 rounds
