Glock 37: light strikes or hard primers?

[Fist_gonzo]

Ok so I picked up a g37 (.45 gap)from another member a couple weeks ago, cleaned it up took it to the range and kept getting light strikes no fire, I used federal american eagle. At least 5 out of 50 failures some took three attempts to fire. So took it home cleaned it all out made sure the stryker channel was clean and dry then put on some parts I ordered, yes one of those parts is a 4# stryker spring, so I took it to the range again used federal american eagle again, it did better only one failure out of 50, that round took 3 tries to fire. Noticed the strike on the primer dosent look any different than the ones that fired on the first try, dead center.Do you guys think its the gun or the ammo?[

The 4lb striker spring is the competition striker spring weight and not made to just swap out and run any ole ammo through the gun. The primers have to be soft enough to light off with the light spring. American eagle ammo primers are too hard. Swap the spring back or change to winchester white box or UMC yellow box ammo. If neither of those work, and they should if you can even find them in GAP, then you really have no choice but to change back to the stock spring.

im gonna try some white box, im thinking its the ammo since I had more failures using the stock spring

Whoa, wat a minute. You had light strikes with the stock springs? Something else is going on. I've lit off 9mm mi,litary primers with all of my stock setup 9mm glocks. The stock springs should be more than enough to light off working ammo. Either the ammo lot is bad, the round isn't fully chambering, or there is bad juju in the striker assy and/or channel. Try some WWB, but if anything even close to a light strike happens, its time to chech the chamber and striker areas for weirdness.

What markings are on the Firing pin?

[Fist_gonzo]

@ jordan its marked "40". Does that mean its a .40 firing pin not a .45? Only marking that I could see, its on the rear, yea the stock spring seemed more problematic but I aslo did find some oil in the channel, cleaned it made sure it was dry put the 4# spring and only had 1 of 50 that didnt want to fire, it took 3 trys to get that round to fire, ive only shot american eagle gonna try some wwb to see if it does any better,

Pointing where its marked "40"

Side note, took apart my g22c, saw that the markings on that are 2 lines on the front of the stryker, also saw on the glockparts website that the 45 gap, .40 and 357 sig use the same stryker?

[Scanker19]

.40, .357 Sig, and .45 GAP use the same firing pin. So your good there. Also a problem could be if your tang has enough wear it could be falling earlier and therefore with less "power" it was made before 2007 since its marked with .40 and not lines. Maybe different ammo will help if not I would definintly look into a mech issue.

Hopefully ill be able to go to the range soon, to see if its the ammo, maybe switch the strykers from the g22 to the g37? If the problem still happens should I just send it to Smyrna? Forgot to state that the pistol looked new pervious owner only shot 50 rounds through it still had the copper lube on the slide maybe needs to break in?

Now you know why the previous owner sold it.
There really is nothing on a Glock that requires "break in".
I would check the profile of the nose of the striker against a known good one. If that proves good I would then strip the spring off of the striker and place it in the channel and push it as far forward as you can. Check the protrusion of the nose from the breechface. Again if you have another slide/striker handy to compare to that would be helpful.
A small burr, machining defect or debris in the channel may be preventing the striker nose from full travel.
If all of that appears ok then try swapping for a known good striker.
If it is still proving troublesome give me a yell, we can get it figured out before sending it back to GA.
SA Friday is correct, stock springs should light off anything.
