I do not have a problem lending guns. I just make sure I know who they are, and have confidence in their ability to safely operate it.
I value my friends more than my guns, and if there is a reason they want to borrow one, that is OK.
I am more particular about hunting rifles than handguns as rifles might be dropped and scopes or stocks broken. But I have loaned hunting rifles in the past.
If I had a friend who needed to borrow a gun because his was not operating properly I would not hesitate to let him borrow mine.
I do not see it as a "No, No." Just make sure you know who and why you are loaning the gun.
Ecclesiastes 12:13 *¶Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man.
14 *For God shall bring every work into judgment, with every secret thing, whether it be good, or whether it be evil.
