I took my Makarov apart and it has no firing pin return spring. What's up?
The short answer: That's just the way it is. It's part of the design. Live with it.
In any case, keep the firing pin clean and lightly lubricated. If this still gives you the willies, you may have to carry it with no round in the chamber. The only real safety you need is the one between your ears. Practice proper gun retention and basic safety and you shouldn't have any problems. SKS rifles are another story, although I suspect this is also largely due to, what we call in computer support, "user error."
You'll probably have to jar it pretty hard (like drop it on its muzzle from 4 feet up) to get it to go off. The state of California (despite all its faults with respect to gun laws) tested and approved the Makarov for safety including a drop test.
However, if you reload, make sure you seat primers below flush with the butt of the case.
[email protected] report the following:
"I have no input on the dropped gun question, but I have slam-fired my .380 Makarov on CCI primers that were slightly (and only slightly) high. I inadvertantly used a 9mm shell holder when reloading, and the resulting primers were almost even (just barely recessed) with the head face."
So, reloaders, please be careful with this!
The cross-sectional picture gives a better look at how the pistol is put together.
Here are some more thoughts on the "drop worthiness" of the gun with respect to the firing pin from a reader:
I have conducted my own drop tests using my Mak 9 mm hi-cap model manufactured by Imez and imported by KBI. Although not scientifically done, I am satisfied that my firearm, at least, won't discharge by dropping.
I removed the ball from a 9mm Mak round manufactured by Cor-Bon, emptied the propellant, but retained the primer. I then cleaned the bolt repeatedly with solvent until the firing pin would move back and forth easily. A drop of oil was added and movement was again affirmed. The floor was a pine board to protect the firearm as well as the real floor, and the firearm was dropped 200 times, per the CA test. The drop height varied from table top to ten feet. The primer round was in the chamber and the safety was engaged. Twenty-three of the drops resulted in the firearm landing slightly askew as its center of gravity made muzzle drops from more that three feet difficult. Nevertheless, of the 177 successful drops not one resulted in so much as a mark on the primer cap. This is probably due to the low velocity of the drop at such minor heights, but I suspect that the minuscule mass of the firing pin and the fact that it can only travel about three millimeters at best precludes sufficient energy transfer to impact the primer.
Anyway, I feel confident that my gun, at least, is safe for carry. I have talked to a number of Mak owners since my first email, and no one has heard of such a faulty discharge.
