I have a circa 1994 Premier II. Each time it is fired, the safety re-engages enough to stop the next shot. This is a relatively unused gun. Les spoke to me briefly and said something about a "tube".
What might be the problem? I really would prefer to not spend the money to ship it back for service... there are some good gunsmiths in my area.
Possibly the plunger tube or your thumb.
Not thumbs. Two shooters, each tested off hand and benched. So what is the tube?
Plunger tube. When thumb safety won't hold it's position and comes off too easily you need to check the plunger tube & spring & may need to:
1. replace plunger and /or spring
2. restake plunger tube
3. sometimes a simple stretch of plunger spring and then replace will increase resistance to stop safety movving too easily
3. replace safety if plunger tube & indent on safety are OK
4. or try removing plunger spring & putting a dimpling drill through the plunger tube & carefull drilling safety until it becomes harder to push off the plunger; drilling a dimple in face of safety that engages plunger. Best left to a competent gunsmith.

I had a similar problem with my PII and I discovered that I was hitting the ambi safety when I fired it. My grip was part of the problem but for me the easiest solution was to send it back to LB to replace it with a single thumb safety. If you didn't want to wait that long you could probably buy the safety from LB and have a local gunsmith install it if it doesn't just drop in.
Before you go ordering parts, remove the safety, remove the safety plunger and re-install the safety without the plunger. See if the safety works OK like that.
Thanks all, especially Bob (#4), and Carrots (#2). It was an improperly staked plunger tube.
