Mauser action fires when safety released

[racinjason233]

I have a Mauser action that when the safety is released it will fire. It only happens when you pull the trigger while in either safe mode and then flip the safety lever to fire position. Has anyone ever run into this before? I can provide pictures...

thanks for all the help guys!

I removed and disassembled the bolt, I added a shim that I made approximately 0.020" maybe a little less. I didn't measure after final fitment. I installed the shim between the safety lever and the bolt, which in turn pulls the firing pin and related components away from the trigger and the sear no longer rests on the trigger when safety is applied in either position. a little more difficult than modern arms to put gun in "safe" mode but is working as designed now. I hope it will kill some game this season, it will be going for a hike with my uncle.

The safety should move the firing pin back slightly by camming the cocking piece back. What it appears to be doing is not camming the firing pin back far enough so that when the trigger is pulled the firing pin moves slightly forward, and then when the trigger is released, the trigger sear cannot return to its proper position in front of the sear face on the cocking piece.
You can either replace the safety with a new one(a new trigger might work too), hoping that will fix the problem. Or, very slightly remove some metal from either the trigger sear(back side), or the cocking piece sear (front side). This should give a little extra space to allow the trigger sear to return to its proper position after being pulled with the safety on.
One shouldn't need to remove much metal. Using a cut off wheel on a Dremel tool and making a couple of light passes using the flat side of the wheel should work.

Does it have the Mauser trigger, or an aftermarket adjustable trigger?

OP, that is a common and very unsafe condition found with misfitted parts on Mausers.

[1]....Is this a Mauser that still has the ORIGINAL safety? [2]....Or is it an aftermarket shroud safety? [3].... Or is it an aftermarket trigger assembly with a "side" safety".

On [1]..[2]...the original and aftermarket FP blocking, "shroud safeties". The Cocking piece MUST move rearward at least .010" when the safety is engaged, to be safe to carry.

What is happening was described by Sailorman.

[3]...is a different issue.

What kind of rifle is it?
Lots of rifles has a "Mauser-Action", knowing what rifle it is might help.

I think the original Mauser two stage trigger one of the best and most robust triggers ever made. However, many shooters don't like a two stage trigger and you did not mention if this trigger has been modified to a single stage only. If so, this may be your problem: insufficient sear surfaces.

I have ruined Mauser cocking pieces and sears by stoning and I found that the angles are critical and subtle. I can't see the inclined surfaces, but the sear face and cocking piece face are angled so that they will slide, under mainspring pressure, back to the "neutral" position when you release the trigger. Guys attempting to lighten the trigger pull often round the surfaces and ruin the angles of the inclined surfaces.

Now something that is not obvious, but that I have run across , is with a standard two stage Mauser trigger, one that has not dorked with, is a weak mainspring. I recommend regardless, that you replace the original mainspring with a brand new Wolff 22 lb mainspring. https://www.gunsprings.com/MAUSER/18...2/mID40/dID175 Do not go crazy and buy a stiffer spring. Often this is all that is needed to get the two stage triggger to reset to "neutral"

Now, if your sear surfaces have been stoned, and a new mainspring does not fix this, buy new cocking pieces and trigger sears and see what fits. This is expensive and inefficient but swapping out enough parts will make the mechanism work safely.
