    My OEM spacer was chewed up enough where it was difficult to push it down far enough to get the rear slide cover off.

    I replaced it with the Farrow version. After 3-400 rounds, no sign of damage to it and no reliability issues.

    That’s what I’m hoping. Mine looks like 12bravo20’s does and it’s only had a few 1000 rounds through it.
    I did notice it’s a bit harder to get get a tool down in there now to take rear cover off. But I suspect after awhile it will probably get peened with the striker hitting it then stop.

    Shoot my 44 a fair amount, and got it mostly to save centerfire ammo. Mine has been utterly flawless thru' 500 rounds, but it's doubtful it will see 5000.
    For the Kanuck OP, sorry that Glock's usual good service isn't available north of the border. Glad you got the issue resolved.

    So the people with this problem, what was the round count?

    Here’s what mine looks like after about 3000 rounds mostly minimags and auto match. It still works fine but getting harder to remove.

    The photo I posted of mine (above in post #17) has 20,000 + rounds fired.

    Some of it will depend on how many times you have completely disassembled your slide too. But It is probably a safe bet that your spacer sleeve does have some deformation/damage to it.

    off hand, I think maybe 6-7 times. And that was too clean the extractor.
    Is this sleeve the one around the firing pin assembly, or the one that is inside the slide that is a PITA to take out?

    Other than every time you strip the slide, does Glock have a recommended replacement interval?

    One thing about the metal versions I wonder about is, what will it do to the firing pin over time? The plastic sleeve has give to it, and is basically a sacrificial part. Will the constant impact of the firing pin on the metal sleeve cause issues?

    The aluminum spacer should not effect the metal firing pin much if at all.

    Now what the aluminum spacer does to the polymer slide cover is another story that only time will tell.

    The spacer sleeve is on and attached to the firing pin. I will post the photo again for you.

    And for the record, the G44 (and G43/43X/48) does NOT use a firing pin channel liner.

    The black polymer piece in the photo is the firing pin spacer. And you can see where the firing pin does deform it.

    Thanks for letting me know, I never even took the spring cups and spring apart on my G44. I just scrub the carbon off the end that I can get with a brush. I will double check again when I get home. But mine does not look like that in the picture, If it did, I would have started researching it.

    I thought of that when I installed it. Might go over it with crocus cloth and polish.

    Well I finally got out to try the 44 and seems to work ok. However out of several hundred rounds at least 30 or so failed to fire. I have a 4-1/2 lb striker spring in it and with the Glock sleeve it never did this once.
    I think the extra friction with the aluminum one is causing this.
    Going to put the stock spring back in and see how that works.
    Looking at the aluminum sleeve there is no indication that it has been used so hoping it works with the Glock spring.
    It would solve a lot of crap if Glock would just supply the sleeve instead of having to get the entire striker assembly which is unavailable up here.

    I am surprised that a 4.5 lbs firing pin spring worked at all even with everything else being stock. When I tried using a Wolff 4.5 lbs spring in my slides, I got constant light primer strikes.And there are a lot of people that have had similar experiences as me. I ended up going with a Wolff 5 lbs spring to solve the light primer strikes.

    For those that are wondering, the OEM firing pin spring is 5.5 lbs for the G44 which is the same for all other Gen 5 pistols.

    Actually I made a mistake on spring it is the 4 lb one from the Macarbo 4, 5 and 6 lb spring set for Glocks. Going to try the 5 lb one and if that don’t work then go with the Glock stock spring.

    Again, I am surprised that a 4 LBS spring even worked at all. I personally recommend sticking with a 5 or 5.5 lbs spring.

    I have two OEM Glock G44s and also played around with trying to get the Nelson 44X slides to function. I have tired many different spring weights and connectors trying to get the G44 trigger to feel more like a G19 trigger. It won't happen and here is why, rimfire primers are harder to ignite versus centerfire primers are and rimfire handguns require a stronger firing pin spring.

    Like I said in previous replies, my first G44 has over 20,000 round shot through it. What I have found works the best is a 5 lbs firing pin spring and an OEM or NDZ minus connector along with a flat face trigger shoe.

    I finally got around to checking my firing pin sleeves. It had a bit of a chewed edge so I ordered up the Farrow offering.

    (I had a hard time getting the iPhone to focus, sorry.)

    At first I could not get the aluminum sleeve to seat and there was a bit of roughness along the cut.

    I used 1500 grit wet/dry to smooth out the cut and the outside of the sleeve, it now seats in the channel just like the factory sleeve does.
    I haven’t shot it yet, when I ill report any issues.

    Stay safe.

    I think I found the problem similar to what riomouse had. The outside is ok but the striker gets hung up on the inside it appears. Going to have to try polishing it to see if it helps. A stronger spring might be enough. I had a rimfire shoot last night so put the Glock one back in along with the 4lb Macarbo spring and never missed a beat in 500 rounds of Federal auto match.
    12bravo20 not sure why mine works with the 4 lb spring and every brand of ammo I tried other than I polished every piece of metal in that pistol and run it fairly wet. Not as much as a 1911 but much more than what Glock says to.

    You might want to buy lottery tickets then.

    Most of the guys on Glock Talk and ARFCOM have not had luck going below a 5 lbs spring in the G44. Some have gotten away with a 4.5 lbs spring but not many.
