I also second the notion to clean the gun if it has been inactive for a period of time. Lubricants can evaporate or change consistency when exposed to air for a long time and many other things could happen as well. What WAS slick and lubricated when you put the gun away 2 months ago may be somewhat sticky today.
Second, I bought my first pistols not too long ago. I grew up on rifles and shotguns, but never pistols. Now I am all about pistols.
Anyway the guy at the gun shop where I shop at is very reputable and probably one of the most respected (and known) gun gurus in my area. People come from all over to buy guns from that guy. His shop is spotless clean and he is honest and professional.... so I asked him how to care for my guns...
He steered me to a bottle of pro-shot 1 step cleaner and lubricant. He then went on (I wish I had a tape recorder at the time) to tell me about various different makes and models of guns. See, this guy also owns a gun range and hence his pistols need to be cleaned often sometimes once or twice a day.
Long story short he said gun owners need to get to know their specific guns. What is good for one gun is not good for another. He said people would return gun model X with grease packed up to the gills of the thing and claim the gun doesnt function properly. Other people will return gun make Y and its dry as a bone and they too think their gun doesn't function properly. Then he cleans it his way and fires 100 rounds without a malfunction.
Some guns love this and other guns hate that. Its like ammo. Some guns simply will not eat certain brands of ammo and others will take whatever you put into them. Same is true for maintenance.
Similarly though, cleaning a gun and maintenance of a gun is specific to your brand (and make) of gun. Whats good for you isnt nessesarily good for the other guy up the road who owns a S&W or whatever other brand you can name.
Currently I own two taurus pistols and I have found that the pro shot works excellent with both for regular maintenance. It lubricates up but its thin enough where it won't collect dust, dirt, and grime.
I also used non chlorinated disk brake cleaner from the auto parts store once for a very heavy cleaning job. I now make a distinction (at least in my mind) between 'cleaning' and 'maintaining'. True blue deep cleaning is only an occassional deal. Maintenance is an every time deal. I wouldnt use that disk brake cleaner every time, but only on an occassional basis or for extreme jobs.
It didnt hurt my gun one bit and it left it clean as a whistle and after it dried out I applied pro shot and gave it a nice wipe down. Both my guns have been flawless.
