then the burden of fouling and wear does not fall upon the "carry gun". I wax the ccw gun's outsides, and use LockEase graphite on the high friction areas. The wax takes care of the rust issues and seriously cuts back on blueing wear, even for use in plastic holsters. The graphite doesn't "hold" lint or grit, doesn't evaporate or drip off, either. I just use WD-40 on the practice gun, a fresh squirt or 2 every time that I go shooting. That's been sufficient, for 40 years now. I don't CARE if the practice gun malfunctions now and then. In fact, I WELCOME the practice at "clearing' such problems. I dont have to waste time cleaning it every time that I shoot, cause I'm not going to carry the practice gun, barring scenarios like I speak of in the next paragraph.
Also, if the ccw gun is seized as evidence after I am forced to shoot some punk (or is lost to me in some other way) all I have to do is clean and holster the spare. No panic about finding a replacement for the ccw gun. No screwups from using a handgun with a different "feel" or manual of arms, either.
If the spare is down while awaiting a broken part (I keep spares of the likely offenders, so such an occurrence is quite unlikely) I can shoot the ccw gun in practice, if need be. Frankly, tho, I can just do without practicing for a month or so. That's no big deal, once you are at a certain level. Certainly it will suffice for the time needed to buy a replacement for the ccw gun.
