Roger that. I appreciate the insight. I may look into filing the plastic down a little just to make it harder to engage, but other than that we shall see. I prefer the safety, I do have little ones at the house, but it’s stays in my beside safe for nowThat's what I meant. I'm agreeing with you about likeing/using safeties.
Just saying that something about your grip or the recoil, or even how easy the safety moves is causing you a problem. One of my 1.0's, don't remember if it was the 9MM or the .40 had a thumb safety that was way to easy to move. Here (years ago on this forum) other people commented about having a similar issue and some of them had removed the thumb safety and filed the notches the detent in the sear block catches in to hold the safety in position a little deeper and also made the transition "point" or hump a little sharper. Both actions make moving the safety require more force/effort. You'd have to be careful not to go too deep or file on the wrong side to change that angle, but it worked for me (took two tries if I remember correctly, but that was about 14 or 15 years ago.
Not suggesting you do it to keep the safety. Just mentioning you're not the only one and sometimes it's the way the safety lever/metal and the detent engage that can make the movement of the safety easier on some pistols.
On a "safety" note (no pun intended) I've had two of mine (the 1.0 9MM came with the safety from the factory) and the 9MM PC (did not have the safety - but I installed one) had problems with the safety to trigger bar engagement. The 1.0 I bought first was okay for a couple years and then had the problem. The 9MM PC had it from the moment I added the safety, spring and detent.
The problem was with the safety in the SAFE position if you pulled the trigger the trigger bar would bump up against the safety arm on the right side of the frame and then twist up and go over it, allowing the sear to release the striker. I discovered it, on the firsts 1.0 after a cleaning session. I always clean them up, lube them, put them together and test the function of the safety, trigger and slide release (goes back to the 1911 days/ways). One day, the old 1.0 9MM released the striker when the safety was on. Surprised and scared me because I wasn't sure just how long I'd used it/carried it since the last cleaning and after cleaning function test. Had to bend the right side safety lever arm upwards a bit to get it high enough that the trigger bar would no longer ride up over it and release the striker. On the 9MM PC pistol I found it right away after installation. Had to bend the safety lever arm on it, too, but not quite so much as the older pistol.
You can bet I'll keep an eye on the new 2.0 .40 PC. Oh, the 2.0 9MM and the 2.0 .45 have not had any issues like that.
