I used to believe that the expensive gun oils were a waste of $.. like many here,
I was a Hoppes #9 guy, for many years.
I tried some REM OIl.. it was OK..
Over the years, have tried a variety of solutions,some cleaners, some lubes, (some advertised to do both) can't even remember the names..
Made a batch of Ed's Red & used that for awhile..still use it on occasion.
I tried a small bottle of Gunzilla..not sure how well it lubes &/ or protects,
but if you clean a barrel with your usual cleaner,(until clean) &
THEN run a patch of Gunzilla through the bore, you may be surprised how the patch looks, after it goes thru your clean barrel.
Have been using Superlube , a teflon grease, on my frames & slides, & liked it as a lube, but my 1# tub is almost gone..
couldn't find the same tub for sale anywhere.
My Gunsmith gave me some extra samples of FP-10 he had on hand.. I tried it, & couldn't believe how slippery this stuff is...
a very small amount & my 1911 slides /slide better than ever before. Amazing stuff..
