I came into possession of a used PM9. It fired reliably in the 30 or so rounds I put through it.
As part of my familiarization with this new-to-me firearm, I installed my 9mm LaserLyte cartridge and did my usual point shooting exercise: Look at a "target" then raise and fire at it without looking at the sights or even the gun. Note how close the red laser flash is to the "target" I had in mind.
I do this to see how closely my natural, uncorrected grip and aim are to ideal for the particular weapon. My Glocks tend to shoot high, owing, no doubt, to grip angle. My Beretta, Walther, Browning and others tend to be very close or right on the money.
I was hoping that the Kahr would be close enough to make it my EDC, but the striker would not activate the switch of the LaserLyte. Looking at the striker, it seems to protrude from the breech face significantly less than my Glocks' strikers.
I'm puzzling now over a way to measure the amount of protrusion and also looking for any kind of specification there might be for required minimum protrusion to reliably ignite a primer. Brownells has a gauge ($40) to measure it but absent a spec against which to compare, I'd still have no idea whether my PM9 is out of spec or not. (And we're talking about forty bucks for something I may never use again.)
I figure Kahr would probably tell me the problem is the LaserLyte and LaserLyte will likely say that, since it works with every other weapon I have tried, the problem is the Kahr.
So, two questions:
Is anyone aware of a specification for required striker/firing pin protrusion to reliably ignite a primer?
Is anyone currently successfully using a LaserLyte cartridge with a PM9?
I really like the LaserLyte for dry fire practice (and highly recommend such a device for any serious shooter). While LaserLyte makes a variety of electronic targets, you don't really need those to get great benefit from dry fire practice with just the laser.
