My Colt Vest Pocket has an issue with the thumb safety. To wit, it allows the striker to fall.
Now, looking at the guts, the thumb safety is dang near superfluous, bearing as it does on that little monkeytail on the rear of the sear. The grip safety, with its positive spring and much larger bearing surface, still locks the sear completely immobile.
It appears that the thumb safety is actually being forced out enough to prevent it from blocking the sear by some manner of cack in the frame, because when pushed firmly towards the right, it functions. Left to its own though, it slides back out of the frame and *click!*
Is the safety engagement surface really that small? (I haven't yanked it and measured with calipers, but we're talking less than thirty thousandths here.) If so, would getting a spare thumb safety be warranted?
