I read somewhere that it's a good idea not to field strip a 1911 after every shooting session. It ever so slightly loosens the slide to frame fit. Just lock the slide back and clean the bore and bolt face. Is this true? How often do you guys field-strip. I just got a new springfield 1911, and want to clean it properly. Thanks

My Les Baer is so tight I just use Kroil and let the crud seep out.

You're not gonna wear out a Springfield 1911.

Field stripping has absolutely NOTHING to do with slide to frame fit getting loose. There's varying degrees of "stripping" a 1911.

If I just run one box of ammo thru it I just strip the slide down & spray out the frame with Gun Scrub. I do remove the firing pin stop & clean that channel out everytime though.

If I'm shooting 100rds or more, I strip the frame completely down, remove the MSH, sear, trigger, the whole bit.

Only thing better than a clean woman is a clean gun!

I can't imagine how sliding the slide off the frame would loosen the frame-slide fit any more than shooting full-power .45ACP...

Depending on useage, purpose or storage, it varies.
For a "range only" gun, I will do bare minimum when in use, a complete tear down before putting it away.
A new gun usually gets a workout to a failure point, dirty, to see how far it can go between cleanings.
When I do a "long term storage" type cleaning, every part comes out and is made spotless.
Gently slipping off the slide can't be as bad as firing it...you may have read that about a "bedded" M-14/M1-A rifle, where some leave it together for cleaning, rather than disturb the bedding.

If it ain't clean I ain't carrying it
