I have a glock 22...40cal what do you find to be the best ammo?

By "jams on ejecting" I assume you mean the casing failed to fully eject, sticking out at a right angle from the ejection port.

This is known as "Stovepiping". Its primary cause is operator error, more specifically, limp wristing.

Your glock is recoil operated. Therefore, the slide must function with the recoil while the frame remains stable. If you do not keep a stable platform of your hand, but instead just kind of "absorb" the recoil by letting your wrist twist upwards, you rob the slide of its recoil impetus, causing it to not go back far enough to fully eject the round.

Your shooting technique may need work.

The next troubleshooting option is a different (lighter) recoil spring.

After that, I'd check the shape and location of the ejector.

And finally after that, I'd verify my extractor was intact and within spec.

That's my troubleshooting list.

Also, the heavier the projectile, the slower the slide. Muzzle velocity is directly related to slide velocity rearward. Had any problems with 135's or 165's?

Also, have someone else, preferably an experienced shooter, put a couple of mags through it to see how it functions for them. This can rule out or confirm operator error, depending on whether or not the firearm still malfunctions in the hands of an experienced shooter.

This was how I found out my sights were off: I thought it was lack of trigger control. But when both of my shooting buddies AND THE RANGE OFFICER shot almost exactly the same groupings as I did, in exactly the same place on the target...I realized it wasn't me.

Sometimes, another pair of eyes and hands will tell you whether or not it's the shooter or the gun.

And for me, I like the Remington 165 Golden Saber, and I'd have it again if I ever have a .40 again.

Which, it turns out, I just may, sooner than I expect.

Wow...you must work in a busy precinct.

First... I'd assume that your "Speer" is a premium defensive load. Second- your boring holes in cardboard at the local rock pit or public range.

Question- Why are you shooting the "good stuff"?

My experience with Glocks... they will fire and extract and eject every thing from Tula and Wolf right up to the $1 a pop premium stuff.

Jam? Define that... double feed? Or a simple stove pipe? I hate to shatter the Glock Myth... but even perfection needs a clearance drill now and then. Assumption- your one of those anal idiots that cleans the gun every time you take a shower and you over lubricate the heck out of the pistol.

Glocks run best with minimal lubrication. Usually a failure to do anything in a Glock stems from dirty magazines or over lubrication of the pistol.

Fact... even a Glock will stove pipe an empty now and then. Fact--- the failure is generally operator induced.

Opinion. unless your made of money... pick up some FMJ for casual and competitive work and save the good stuff for carry.

40sw is pretty hot. Almost any jhp will be fine in a G22. Find something cheap like Remington and run some through. If no feeding issues, it will do fine.

If you were shooting a short barrel 380, then you may want the premium Gold Dots or Corbon DPX, but in a longer barrel 40 sw....just plain hollow points will do fine.
