New to the forum with another thumb safety question

[230X8]

I replaced my thumb safety with an extended unit and now it moves up halfway when the pistol is uncocked, not a problem under normal use but, should the hammer ever fall an a dead primer and it get bumped up during the confusion I'd have to fight the slide over it to rack a fresh round. Any thoughts or is this common for aftermarket "EZ-FIT" parts not fitted? Thanks in advance for any advise.

I believe there is a trick that gunsmiths and good gunmakers do to alleviate your problem. It is called drilling a dimple in the safety. They also do this on the other end of the plunger tube, the slide stop pin. Compare the two parts you have and see if there is a difference or lack of dimple.

I have never heard of a dimple being drilled on a thumb safety. I have dimples on the slide stops of my pistols, but on a thumb safety? I believe that when you fit your safety, you overdid it at some place, but let's wait for others more experienced than me to comment.

Generally speaking, thumb safetyies don't need a dimple, but depending upon who made the safety and the position of the holes in the receiver, you might find one that wants to ride up. Before dimpling (is that a real word?) the safety, check the plunger and spring to make sure they are in spec, undamaged and the spring has good tension.

The only fitting I did was removing the thumb safety, hammer and sear from the bags they were packaged in, all from CMC. Looking closer last night I noticed that the thumb safety is not traveling all the way down to its fully disengaged position due to it hitting the grip panel and a small wear mark on the face of the plunger tube. I guess I'll sand down the panel and maybe reshape the extended lever. It does have a "dimpling- dimple" for the plunger tube pin to ride in when fully disengaged, which not happening to my peepers. Now, where's that Dremel?

A tear-shaped detend you mean? Yes, that should be there. And stay away from that Dremel, you may hurt yourself (or your pocket).

Yes, a tear-shaped detent, for the plunger tube pin to fall in.
