It's true. The original ones had a longer minus stamp (known as the 'long minus') than the ones that have been out since late 1992 or so (some time after the 92 armorer's manual came out). The originals are 3.5lb and the current ones are the 4.5lb. The newer ones are often referred to as 'short minus' by those in-the-know. They also seem to have a slightly different finish on them. Interesting to note that back in the day, if you bought a Glock with a long minus connector in it, the owner's manual had a red ink hand stamp on the front that said something like 'this pistol contains a 3.5# connector' (I'm too lazy to go down 2 flights of stairs and back up just to get the exact verbiage).

The big problem is a lot of third party parts shops will sell the current short minus as a 3.5lb, which is actually a 4.5lb connector. I get into more arguments about that.

What's worse is that Glock still sells pistols with the short minus in it, but the replacement part is a restricted part from them, and requires LE letterhead. When I was in Smyrna last year for my Advanced Armorer recert, I asked about it, and was told there was some legal issue that caused Glock to do that. Same with the marine spring cups.

If I can, I'll try and do some pics for comparison.

On the left is a 'long minus' taken from a Gen 1 17LP. It's a 3.5lb connector. On the right is the current 'short minus' 4.5lb connector that's stock on guns like the 34 and 35. Only the short minus is available these days.

58sniper- are you the member who was selling some of the long minus connectors?

No. Someone was selling them here, and I ordered a few, and they turned out to be all short minus connectors.

Any chance of getting a trigger pull gauge reading comparing long and short? I assume long is more of a rolling break with less ‘wall’?

Yeah, let me finish up some stuff this week and I'll do a comparison.

Not sure I'd pay that much for a used part - if it's legit.

So, first round of testing is done. I think I'm going to redo it, but some interesting notes. Tested the following:

1. Glock 'short' minus (current production)
2. Glock 'long' minus (taken from a Gen 1 17LP)
3. Glock standard (Gen 3)
   
4. Glock dot (Gen 4/5)
   
5. Glock plus
6. Ghost Blue Lives
7. Ghost 3.5
8. Ghost Edge

Each was tested 10 times on a Gen 4 G19 that has ZERO rounds through it. Pull was measured by Lyman digital gauge.

Current Glock minus connector came in at the lightest with an average 4.08125#. Glock long minus came in with 4.578125# average. That was VERY surprising - as I expected the long minus to be less than the short minus - even if by a very small amount). Not surprisingly was that the Glock Plus came in as the heaviest at 6.91875#. Most consistent was the Ghost 3.5, with a difference of 0.275# between lightest and heaviest reading.

I'll likely do these again as I noticed the gun was a bit dry (albeit consistent through the tests). After that, I'll do a detailed blog post with the findings.

I had to go look thru a bunch of old Glock parts in my stash & I found a Long Minus Connector that's stainless & has an S on the bottom tab, It came out of a 2nd Gen 17L, It's polished mirror smooth.. Also found a GAP floorplate that was an extra that I used on a Gen 2.5 26 too..
IIRC I put a Ghost in the 17L way back when & when I sold it the Ghost was in it..
Never really thought much about it till I saw this thread..

Also 58sniper you where able to use a minus connector in a Gen 4 G19?
I thought that the Gen4s used a different connector??

Yes. My gen 4 EDC guns all have a short minus in them.
