Small problem with Timney Trigger

Sisco · June 13, 2002, 04:30 PM

I put a Timney Sportsman trigger on my 98 mauser action this afternoon. Not quite a "drop in" install. Trigger mated up to the action just fine but wouldn't fit the stock. Some wood work fixed that along with filing on the trigger guard to give the new trigger clearance.
However, the handle doesn't lift soothly when cocking. Requires more force to get it all the way up than it used to. Once it's cocked it lifts fine, works good if the reciever is removed from the stock. Trigger pull is great, the safety works OK.
Perhaps I still need to remove some wood or metal on the guard?

Try assembling the guard to the receiver without the stock (don't tighten down the action screws). If it still binds, the problem would seem to be in the stock. If it binds out of the stock, you can probably tell where it needs work.

Most Timney's that I have installed on Mausers have required that I mill about 1/32" from the inside surface of the trigger guard. This is done with an end mill plunging into the dished out area around the trigger slot and cutting both sides out a 1/16 or so and each end of the slot about the same. From the outside you can't see it, but the interior surface is recessed a bit. I recently did a commercial FN Mauser that required the same treatment. I suppose you could Dremel a relief cut, but it wouldn't be nearly as easy or smooth.

Didn't check the inside surface of the guard, I did widen the slot to get the trigger to fit through.
It's my amateur understanding that the trigger housing should not be touching anything inside the stock - correct?
If so what if I coated the outside of the housing with some prussian blue and trim away any material it may be touching?
I will try attaching the guard to the reciever without the stock and see what happens there first.
Thanks!

You are correct. The trigger parts should not contact the wood. By taking the barreled action out of the stock, you can see if the guard is binding on the trigger housing. Depending on how tight you snug up the screws, that could bind the action. The Prussian blue trick works fine, but you may learn everything you need to know by just assembling everything without a stock.

Good Luck!

Got it!
Put the guard on the action out of the stock, no problems. Applied the prussian blue and found some spots it was touching - mostly at the rear of the trigger housing.
Got out my trusty chisel & files and it binds no more.
Thanks for all the input!

So, how does your new trigger compare to the old?

No comparison! No creep, breaks at 3.lbs., no overtravel. Limited time at the range so far but groups are much better.
Well worth the effort.
