40 s&w?

[micro911]

I have examined a lot of officers' Glocks in 40 cal and found no problems at all.

[SVT-40]

We had some issues when our agency started putting lights on our duty Glock 22's....The factory fix strangely enough was to replace the mag springs with springs of a slightly stronger spring rate...After the mag springs were all swapped no more issues....

It all had to do with dynamic flexing in the frame, which caused timing issues...The stronger springs fixed the timing issues...

.40 is not any less reliable than 9mm. Glocks are pretty much the AKs of the handgun world having earned a reputation for reliability. (provided you don't shoot limp wristed).

I think the issue now is that advancement in 9mm has gotten to where the effectiveness of the two rounds are nearly identical in certain loads. Federal HST for instance, one of the more popular duty ammos has virtually no difference in terminal ballistics between their 147gr 9mm HP and they 180 gr. .40 HP. I would carry 9mm HST if my agency allowed but it doesn't.

I carried a G22 (primary) and a G27 (backup) for years as an LEO, and never had any issues. I shot a lot on my own time, and went through various classes where we shot a lot of rounds. Zero issues, and I carried two different G22's (one personal one department issue). I trust my Glocks, and the .40 is a great round IMO.

Surprised about the Berettas. Although your rentals probably had a lot more rounds thru them than mine, I have thousands thru mine with no problems. It was issued to me in Jan. of 1990 and I bought it when I retired in 2003. I still shoot it at the range often. The only fix was to the locking block and I had no problem with mine. The dept. had had some crack, so they replaced everyone's as a matter of course.

I concur with Retired. Our department issued Beretta 92F's (9mm) around the same time period. Never heard of anyone having issues; great gun. We were 90 sworn at the time.

My brother worked for another local agency, they issued Glocks (don't remember the caliber or model). He liked it and never complained about it. I shot it once and didn't like the feel.

I hear a lot of negative talk about glocks chambered in 40 s&w?

I purchased a glock 23 not to long ago and a bunch of people are telling me it is not a reliable gun even though it's a glock? I just find it hard to believe?

what are your guys opinions?
Thanks!

If you watch the high speed video of Glock firing, you will see the frame twist and turn. If you install a relatively heavy light unit for the frame, it will affect the movement of the frame and slide. I think it is the problem. See the following comparison slow motion for different pistols.

Darn, so does this mean if I attach a pistol bayonet to my Glock rails it will reduce the reliability?

It will reduce more than reliability...

I owned two Glock 23 GEN3 pistols. NO problem . Very good guns. I also owned a GEN4 G22 No problems . Accurate and reliable.

I sold them all because I prefer 9mm and .45 ACP, not because there is anything wrong with Glocks in .40

PS. I currently carry Glock GEN4 in 9mm on and off duty.

I really like my 22 and 36, I prefer a 9mm or 45 over the .40. It just seems rougher than my 45's. As far as malfunctions with the mounted lights, I saw it a lot with the TLR's not so much with the sure fires because they just snapped onto the rail. The Streamlights attached to the rail and had a tension screw that was the problem. People would tighten them too much causing the rails to squeeze in like a vise. The slide would get hung up while cycling because the slide rails were being forced inward. Glock reinforced the light rails on the Gen 4's I think. I do like 1911's, but in my experience there was more malfunctions, ftf's than the glocks. I think a lot of it had to do with the magazine follower and springs.
