GHOST Turbo Maritime Spring Cups Gun Stock Accessories

Easy Installation, product fits as good or better than OEM spring cups. As advertised the cups have less friction inside the plastic firing pin channel liner. I assume this would equate into less weight for trigger pull but the amount is not perceivable or I couldn't really feel a difference in trigger pull other than pull/travel of trigger was smoother. This was installed on a Glock -19 Gen 4 9mm. Function test and shooting went flawless and equated to same reliability as standard OEM cups. Reason for purchasing these was to reduce possible clogging or debris build up in muddy, wet conditions. As I have occasionally had my firearm dropped in mud or submerged (boating) and liked the feature of self clearing the firing pin channel as the striker is moving. The OEM cups form a sealed plunger that has tight tolerances not allowing water or mud to push past the cups it tries to force any trapped material (water/mud) out thru the small firing pin hole in the slide. thus far happy with the purchase and would but again, not a must have upgrade unless you possibly expose your glock to the elements as I described.

I could not tell you if they are worth it. The packaging was quality and the product itself looks to be top notch. However they lock up my firing pin and does not allow the trigger to reset. Be aware of the possible fitment issue with aftermarket options.

good quality slotted spring cup, easy to install, and very happy with the results. Pew Pew Pew!

Haven't had any issues with it

Bought this because of the obvious benefits it provides.After about 1000 rounds my Glock 48 started having all sorts of weird failures (quite literally failed in all manners possible relating to the firing pin).Thought it was the ammo, changed the ammo.Thought it was my grip, took lessons and was insured I had a great grip.Thought it was my trigger, replaced that.Thought it was my magazines (was running the shield arms mags and aluminum mag release), replaced all those back to OEM.Thought it was my guide rod, switched to a tungsten one then switched back when the issue persisted.Thought I wasn’t cleaning my gun correctly. Meticulously cleaned and lubed everything. STILL THE PROBLEM PERSISTED.So finally in a Hail Mary I measured the length of the firing pin with the turbo cup’s vs the OEM cups. The turbo cups were separating under load and my firing pin was not operating correctly.Yes I lined the cups up correctly, trust me I did everything right.If you rely on your weapon for any reason, DO NOT BUY THIS PRODUCT.

Nice little upgrade for your Glock. Priced right so why not.

Quick shipping, item arrived was accurately described by shipper and tracking info was on point. I would be happy to purchase from this seller again in the future. Purchase to delivery was seamless. Thanks again. A++ Happy with my marine cups.

They seem to work fine in leu of the OEM regular spring cups, and the fitment is correct. I personally do not plan to try them out in the water, but if that's your thing, then more power to you.
