Glock 23 jams only w/ tactical light attached?

[jocko]

honesty is always the best policy, therefore to me it is not bashing.sorry you had issues to. not good for any gun owner.

...I traded it in on a Sig P239. Lost money on the deal, but what are you gonna do?

What I did was buy a few +10% magazine springs and got my .40 GLOCK running 100% with tac lights - a lot cheaper than trading it in on a loss.

A number of LE departments have had this trouble with newer Glock 40SW models and lights. Glock has been going nuts trying to solve this problem. Some of the LE departments have gone to 9MM Glocks which don't seem to have this problem.

I'd be going nuts too, the thing defies normal analysis.

Added weight inhibiting rearward motion of the frame shouldn't be substantively different than simply gripping the thing more firmly. If frame recoil inhibition was the culprit a Glock could not be made to run from a Ransom rest, could it?

For what it's worth, I was never able to coax a malf out of my G21 with an Insight M3 light.

I could picture a miniscule possibility of stuff going pear shaped with a Viridian X5L - my example can clamp down on a rail like a Nile crocodile possibly warping a polymer rail point but even that's an extreme stretch. Is there anything weird about the specfic light involved?

Has the same problem been noted with M3s?

There have been reported issues with the .40 S&W Glocks (G22, G23, and the G35) with various weapon lights. Some seem to work with the lights while others don't. This is a well documented issue on other forums. Some workarounds have been to of course, replace the OEM springs with after-market springs and to update the magazine followers to the current #8 followers.

Even after the above changes, the results have been mixed and not 100% successful. The only option that Glock recommends is to use their branded tactical light. Even those have reported issues.

The believed underlying cause of the issue is the changing of the frame flex during recoil. As I understand it, the Glock .40 relies upon a certain degree of flex in order for the gun the cycle properly. When a shooter introduces a frame mounted light/laser, the angle and degree of flex is altered to a point that it changes the frame geometry - causing a failure to feed. Does this geometry change accelerate or decelerate the slide, I don't know.
