I recently purchased my first Glock (Glock 19 – 9mm) which I intended to use as my primary self defense gun. It’s replacing a 10 year old H&K .45 I’m using a guide rod replacement laser by Lasermax. My range test today was less than impressive. While the accuracy was great, I had about 9 operational problems in 100 rounds fired. 1.Breach would fail to close completely after cycling a round. The slide would stop about a 1/8 of a inch short of actually closing. A gentle nudge forward would lock it. (happened 5 times ) 2.In one case the slide failed to lock back after last round was fired, but it did cock the gun resulting in a dryfire. (1 occurrence) 3.A couple of miss-feeds (bullets entering the chamber at an angle), but no stove pipes. (3 times) This was with new Glock mags and average quality PMC ammo. It would seem that these can all be attributed to improper tension on the main recoil spring. With both the factory and the lasermax spring, the Glock’s slide seems to be under more pressure than my Sig, H&K or M9. So without simply blowing a lot of rounds using the factory spring, any idea how to diagnose what the problem is? |

Quoted:
More than likely, its the Lasermax. Just swap it out for the original recoil spring assembly for your next range trip.. this stick w/ the stock guide rod/spring and your glock will be very reliable; if you want a laser, opt for the Crimson traces, where the mail module is not internally placed w/ the critital componets, like the rod/spring assembly |
| As others have said, it's the Lasermax. More specifically, it's the recoil spring on the Lasermax. I find the Lasermax recoil springs to be very heavy compared to stock, and it is likely "over sprung" for 9mm. The spring is not allowing the slide to move back far enough consistently. It may soften with some additional use. |
| I installed the LaserMax in my G26 and G17 before I fired a round through either - 500rds each and no failures of any kind. If anything, the LaserMax guide and springs look to be far better quality than the stock Glock components. Did you double, triple check your installation? If it was put in incorrectly, and it is very easy to do, replacing it with the stock piece won't prove the LaserMax defective. Also, were you using factory 10rd mags in your 19? I have read of folks experiencing problems with these occasionally when brand new. I have read that LaserMax customer service is good, should you have to warranty it. Anyway, hope it works out for you. |
