Yeah its obvious looking at this video and studying the design that none of the safety's are being defeated. As long as the trigger is working properly.
Here's a second, more detailed video from Johnny Glock
I just put this together, it's quick and dirty but maybe it will help understand the lack of a drop safety.Yeah its obvious looking at this video and studying the design that none of the safety's are being defeated. As long as the trigger is working properly.

Yep youre right. As youve shown in that video the sear being independent of the trigger bar raises another issue. That spring could depress by a strong whack to the butt. My trigger however hasnt stuck once on me but it came from the factory adjusted with too little take up and was pressing on the plunger safety right out of the box. I had to back out the trigger adjustment screw almost all the way to free it up. Hmmm ya got me rethinking this trigger. Definitely wont be carrying it. Like you said "range use only" until they rethink this. Thanks man you rock.I just put this together, it's quick and dirty but maybe it will help understand the lack of a drop safety.
Absolutely doesn't surprise me. This trigger has so much potential but has a glaring issue that I personally wont overlook. It got yanked out of my pistol, its going to stay in my safe period. I dont need a sig p320 accidental discharged story in my life. Sorry Timney good swing but a miss.Just as a follow up. I took the Timney in my Gen4 17c to show a buddy while he was doing some upgrades on a shotgun for me.
I decided to try jarring it with a rubber mallet on the top of the slide. The gun is one of my favorites and has Dawson sights so I didn’t go crazy but the connection with the firing pin lug clearly changed with the first hit and released with the third.

This is very interesting. Thank you for taking the time to post. I have Timney’s in three competition guns (2 G19s and one G17 (dedicated to a SBR PCCO). All three at 2.5# trigger pull. I’m really liking these triggers and will keep using them for competition matches but after reading your post I need to make a change on “Make Ready” command. I have a routine where after inserting mag and chambering a round, I tap the bottom of the mag to make sure it seated well, and tap back of slide to make sure it went fully into battery. I think from now on I will do this BEFORE chambering a round 🙂. Thanks again for your post. I will also be doing some drop safety experiments on my Timney’s.Just as a follow up.

Edit: Thinking more about this, I think I need to experiment with my “make ready” routine using my armorers back plate to see if tapping bottom of mag and back of slide causes any movement on the connection with the firing pin lug. It would not be good if there were enough movement where the lug was just barely holding where holstering and drawing was enough movement to release the striker prematurely. Any other suggestions you may have to further experiment with this issue would be appreciated.This is very interesting. Thank you for taking the time to post.

When the firing pin lug released on the third whack, would the safety plunger stop it from discharging a round? Is there a (safe) way to test this?Just as a follow up. I took the Timney in my Gen4 17c to show a buddy while he was doing some upgrades on a shotgun for me.

The firing pin safety should prevent the discharge of a round. But there’s two issues to keep in mindWhen the firing pin lug released on the third whack, would the safety plunger stop it from discharging a round? Is there a (safe) way to test this?
Thank you for the additional information. I also found your YouTube video on this issue. Very well done. Very happy with Timney for competition matches but based on your thorough analysis I will definitely keep the drop safety issue in mind and act accordingly 👍The firing pin safety should prevent the discharge of a round. But there’s two issues to keep in mind
1) the firing pin safety is not 100%
Glock has improved the design of the firing pin safety a few times over the years but it’s still a mechanical part operated by a small spring. Glock warns in their manual that every mechanical part will fail at some point.
2) the lack of a drop safety will test the firing pin safety more than a stock Glock would. A different way to say this is a factory Glock would not normally have to depend on the firing pin safety to stop it from discharging from a drop.
I have played around with this setup a bit more. I found a warning in an old Glock manual that the Glock could discharge if dropped on its nose. Glock has since upgraded the parts to prevent this but I took it as an indication that the weak point was the nose of the gun and not the butt.
I found that dropping the gun on a padded carpet floor from below my waist was enough to cause the firing pin to release about every 3-10 tries. I suspect the angle of the drop is more important than the force as it pertains to the Timney releasing the firing pin.
To check the firing pin safety, I placed a piece of tape over the face of the slide so it would indicate if the firing pin had penetrated. I have not had a failure of the firing pin but I haven’t dropped from higher than my waist. I would expect the current firing pin safety design would need more force than the Timney does.
I still use the Timney in a competition gun and enjoy it, I just wouldn’t want to carry it as a self defense gun where I might be in a physical altercation.
