Ghost Maritime Spring Cups Compatible with Glock

Bought these because I lost one of my stock cups for my Glock 27 Gen 4 and wanted a replacement fast and I had Prime (also this was around Christmas so a lot of vendors would take too long).No trouble installing it to the striker, but upon inserting the striker back into the slide, the fit was very tight. Upon pulling the striker back out, I managed to also pull a black plastic cylindrical tube out that the striker spring and cups slide along in. I can't find the name of the part on these online parts lists (no it's not the spacer sleeve but sits farther ahead of it).Putting everything back together, I noticed the trigger was much more crunchy and gritty. Firing at the range resulted in the slide returning just slightly out of battery quite often, sometimes as often as every other round. No I was not limp wristing it, but gripping extra tight helped prevent this a little bit.Messing around back home revealed that it was getting hung up slightly out of battery, right around when the sear engages the striker. It was worse when I returned the slide while holding the trigger back. Even with the lighter 6lb Ghost striker spring, the forces from the striker were outdoing the recoil spring at that point.So I took it apart and sanded down all the nubs on the spring cups and polished them so they'd ride easier in the little black plastic channel. No hangups after that and the trigger smoothed out.***TL;DR: The nubs may stick out too much and cause too much friction along the striker channel and cause the slide to fail to return to battery slightly as well as a grittier trigger. You may have to sand them down a bit for it to work reliably.

I have to say that these actually work perfectly. I honestly just bought them to test em out. Sure enough, it worked. I have a Glock 23 Gen3 and just for the fun of it I tested it out underwater without these spring cups. I got 7 rounds out of 13 to fire underwater. I was getting light strikes with the stock spring cups. I installed the Ghost spring cups and sure enough, 13 out 13 fired underwater. I did this with 3 full mags and it worked every time. Now just to let everyone know I do not plan on getting into an underwater fire fight any time soon. But if I did I would definitely win with these on my Glock. It is good to know that these will make your Glock that much more reliable. As any Glock owner knows, right out of the box these are one of the most reliable handguns on the face of the planet. The underwater test is about the only thing I have seen that slows down a Glocks reliability. Well not anymore. Totally worth the few bucks.

Let me start off by saying I did not purchase these spring cups to shoot underwater. I purchased them as a way of increasing overall function of my firearm. If it gets wet or debris in the firing channel, I want my gun to still fire. Glock's are known for their reliability and function, but any additional edge I can get I take. In this case the spring cups were easy to install and replace the old ones. They function as the original spring cups did and I can see no difference thus far. I have not yet been in an environment to fully test out the "under water" or "with debris" claims, but I can say they do not hurt the function of my 4th generation Glock 17. Worst case scenario thus far is that the piece does nothing for the firearm. I don't see it as a hindrance in any way. I just hope they increase Glock's already well known reliability.

You need to watch a Youtube video on how to install these. You will need a roll of electric tape. The video explains why. These Maritime cups offer self cleaning to the striker. They allegedly allow a Glock to fire underwater and chamber a new round. I put them on my G17 Gen 4. These cups are extremely small. You may want to order an extra set. They will go airborne and be lost forever if a spring unexpectedly gives way. My first attempt at installation was a major head ache and then the striker would not fire. I installed a second set and the striker works fine. Not a must have and keep your OEM ones.

Like other reviewers have commented you may have to shave-remove material from the posts that stick out in order for your striker to go back in. I used a file with the cups attached to the striker. Took a minute to get em all. Big deal no, should I be forced to do it, no especially not for the asking price. Gun goes bang though so all is well

I have not tested these myself, but I’ve seen enough YouTube videos to convince me they work as advertised. Since I am around the water all the time I decided it couldn’t hurt to have them in my EDC. Hopefully I will never need to find out if they really work in an emergency. They are very easy to install and only took a minute or two. I’m sure if you just wanted to modify the originals it would work just as well.

I'm not so sure that these will actually do what they say they will but I will say that they fit correctly for the most part.I noticed a bit of drag on the striker when these were installed but the firearm functioned just fine.More testing to determine exactly what I think.4 stars instead of 5 because of the drag on initial install and I'm just not convinced they will do what they say.EditIn retrospect, I do not feel this is a necessary item and ther is a bit of Hype surrounding it.It looked like a good plan, but it is pricy and I think I'll stick to the stock ones from now on.
