OK, I'm new here, searched the forums a little bit.
At least once every 2 magazines I fire, there is always 1 that does not fire. I look at bottom of the casing and there is a dimple, but it did not fire.

Is there an adjustment that will make the pin hit harder?


Thanks

When you load the mags, lightly tap the primer side og the mag aginst your hand. This will "set" the rounds properly in the mags and all rounds will fire.

What ammo mfg are you using? Sometimes one brand can give you problems with light primer strikes.

Sounds like an issues with the primer not getting hit hard enough by the firing pin. This is an issue of the hammer spring UNLESS you are using re-loaded or re-manufactured ammo (yours or someone elses). When you reload, or when the case is "primed" with a primer, is for some reason it is not seated properly, the first hammer strike will seat the primer and a subsequent strike by the firing pin will now fire the bullet because a.) The primer is not seated a bit tighter in the bullet case, and b.) You have already indented the primer to some degree and now it can pinch the priming compound and ignite the powder charge.

There are differences between hardness of primers. Moreso in rifle primers, such as those used in 5.56 (.223) and other calibers than small pistol primers, but I have seen charts with the variances of primer hardness, so it does exist.

There are no adjustments to the pistol. The primer strike is all related to how hard the hammer is hitting the primer (if good ammo is ued) and would relate directly to the strength of the hammer spring. Make sure there is good lubrication around the hammer and the spring asembly, and that it does not hang up or is bound anywhere. If all else fails, it would need to be sent to Bersa for repair, or if you are handy, you can replace that spring yourself. They are not expensive.

It really should fire all the time EVERY time. That is the whole reliability design on centerfire cartridges over rimfire cartridges. There should be no issues with a round not firing.

I have a problem with 17hmr not firing

New hornady amo . I get a dud every 5 or 10 shots .
I can take the dud and try it 3 times and get 3 dents and no fire. try a fresh one and bang.
I think primer material is not infused corectly . if you know what I mean.

If the dents look good, my guess is bad ammo. Compare it to the dents in the primers that fired. Do they look the same?

Welcome to the forum. If a change in ammo does not solve your problem, ya may want to check out the safety/decoker to make sure it is completely disengaging. This condition was discussed in a thread or 2 here. Seems the firing pin drags on the fring pin block caseing light strikes on some guns if it is not completely disengaged. But, to me it just sounds like an ammo problem. The other condition usually happens pretty often once it starts.

Sometimes there is a burr in the firing pin channel. Pull the pin and if you can run some 500-600 grit sand paper in the channel to smooth it out. Also check the firing pin also for any tiny burrs or rough spots
