Re: 1911 Thumb Safety
Springs can weaken with repetitive use, so time may be the cure here. As Alpo and RJay have said, it should have a distinct engagement. And I agree that it is better a tad hard than loose. You might, in your spare time do some drills and practice thumbing the safety to help loosen it up. Little drills are good at building muscle memory as well. We do some dry fire drills at work when we are at the range and it really suprises me how much they help.
I would recommend Silver Bullet Gun Oil as well. Awesome stuff, if you are in the market or willing to try something. There are several people on here that now sell it for good reason. You can do a quick search for it if you would like some info or reviews.
