G22 w/ TLR2 relyability

Discussion in 'Sights, Optics and Lasers' started by JDinNC, Aug 31, 2010.

  1. I want to use my G22 with a TLR2 for home defense. I just read a gun magazine that explained the problem Glock 22 .40's have with Streamlight TLR2 attached. This effected many police departments. I had heard of it before but didnt understand. Malfunctions could be caused by the high velocity of the slide with 40's. The slide moves so fast that it could close before the next round fully feeds up from the magazine causing a malfunction. Would using the 180 gr. result in slide velocity being any slower than with 165's? If so, maybe the 180s would be a better choice. I like speer gold dots.

    I have a G22 with a TLR-2s. I shot everything from 155's to 180 .40 grain bullets and my 40 to 9mm conversion barrel, with the light/laser on the pistol. No problems.



  3. Never had a problem with the light on my G22. 4000 rounds

    My G17/TLR-2 has run a few thousand +P's through it with no problem!
  5. The issue is with the "super intense" .40 round from a G22.
  6. streamlight has a text file on their web sight addressing this. they say it's a mag issue and does not affect every G22.

    i have an Insight M6X light/laser and never had an issue.

    JD went and put 300 rounds through my G20 with the light problems there either! Thats with my hot 180 JHP loads! 1250+ fps hot 10mm!

    PS next time I go out I'll try a few hundred through my 29 with the light attached...just for giggles!

    Zero problems with 22's and 23's, with tens of thousands of rounds, with TLR-1's, and we're talking about scores of glocks. Don't know about TLR-2.

    This is the blurb from Streamlight:

    Q: Are there Issues Using Tactical Lights on Glock® Pistols?
    A: Some Glock® .40 caliber pistols, models 22 and 23, exhibit feeding malfunctions, either nose down or nose up (stovepipe), when used with tactical lights. The problems tend to occur with individual guns, with some pistols becoming totally unreliable while other identical, even close in serial number sequence, guns have no problems. Most models 22 and 23 are reliable.

    A sensitive gun may malfunction with any tactical light - the TLRs, the older M models, and even Glock®’s own brand. There is evidence that the problem sometimes develops with use, and may progress until the pistol is unreliable even with no light attached. On the basis of testing by Streamlight, we believe the problem is magazine related. It appears that the rounds are unable to rise fast enough for proper cycling. We have observed proper feeding for the first few rounds, consistent failures at mid-magazine capacity, and a return to proper feeding of the last few cartridges in the magazine.

    We have tried both stronger and weaker recoil springs, and compound-action recoil buffers, all without success. Sometimes new magazine springs, either new Glock® or Wolff, will cure the problem. In one case of a pistol which was totally reliable when new but progressed to malfunctioning on every magazine, even with no light installed, we found two solutions which restored reliability, but which might not be acceptable to some users. The first was using 10 round capacity Glock® magazines. The gun will not cycle reliably with 15 round mags with their steeply stacked columns but works flawlessly with 10 round mags. The second solution was a new magazine follower from Brownells®, their part number 069-000-006. When used in a 15 round magazine with a new spring, reliability was restored. However, the follower would not lock the slide open after the last round.

    Ammunition is also a factor with any weapon. Some brands and weights may be totally reliable while others jam repeatedly. Make sure your gun is thoroughly tested with your duty ammo.

    I have a TLR-1 on my G35 and I have between 2-3 FTF in 50 rounds when I shoot duty ammo (Speer Gold Dot 180 grain). I have no problems with practice ammo, which I think is reloaded. So, I'm not really sure what exactly the problem is, but there certainly is one.
