I use slixshot nipples in all my revolvers. Same nipple on each gun means one cap size to purchase.
I have......
1851 Colt Navy Uberti
1858 Remington Uberti
1858 Remington ASM
1860 Colt Army Uberty
Colt 3rd Model Dragoon Uberti
The RWS 1075 caps fit like a glove. One cap size lets me buy in bulk and save. I never have a fail to fire, caps never fall off & cap jams are rare.

This is my third set of SliXshot nipples. They work great, are easy to clean and just give me more confidence that my 1851 Navy will go bang when I pull the trigger. My only "complaint" (hence 4 Stars) is the price. But, I don't see the need arising to replace these nipples ever again.

Reply from Slixprings:

All of our products are made in the USA (hence the price).

Works great so far.

A great plus for my Pietta revolvers used for N-SSA matches.

Exceptional product, the caps fly away in pieces, practically eliminating jamming due to pieces of caps.
In the large frame Uberti there was no cylinder jamming. As soon as I receive a discount coupon, I plan to buy three more sets of nipples.
I recommend it to everyone.

Well, I really cannot rate these yet as I am waiting for some RWS 1075 Percussion caps to become available. All the other reviews have raved how much they like them. I give you an update when my caps come in and I can load up the revolver and do some shooting.

My pistol has given me better performance than ever.

With the factory nipple parts of the cap would get down in the hammer and stop the hammer from moving. With the Slix nipple I do not have this problem

Slix=Shot nipples are the first thing I replace on my cap & ball revolvers.

Shooting the Pietta Dance revolver and these nipples are fantastic! I've not had one cap jam yet.

Thank you for making quality U.S.A. made tools and parts. The Slix wrench worked perfectly after I broke a cheap Italian wrench trying to remove the nipples from a used Pietta.

I installed Slixprings stainless steel nipples with choke tube lube and expect no more problems.

I have these in all of my Old Army and Pietta Remington cylinders. Truly worth the price. I never have a problem with spent caps falling into the action.

Perfect fit fast service

Aces all the way. The first thing I do for a new (or used) percussion revolver.
Eliminates 95% of cap related jams. You won't be sorry.

Nipples fit perfectly in gun. Haven't used them yet, but not expecting any problems.

I purchased these for a Uberti new army Remington perfect fit and function would recommend to anyone. I have them on a Uberti 51 navy also and they have eliminated cap sucking entirely. Money well spent.

Replaced nipples in six guns. Very excellent product.

Fit well consistent size. Reduce hammer bounce

Outstanding Product

Each time I purchase a black powder firearm the first thing I do is clean and inspect and Install SlixShot's. After finding this product I don't know what cap jams are.

Also check out the Slix Hand.

These solved my cap malfunctions

I could not find #10 Remington caps anywhere. #11 CCI, no problem. I was crimping caps which wasn’t a great idea. Changed nipples to SliXShot and now I can use #11s without issue. And the caps stay in place after firing. No more digging caps out of the hammer or the action.

They work great to replace the factory nipples on C&B revolvers.

I replaced the factory nipples on my 1860 Colt 44 due to the caps getting stuck in the action and rendering the gun unusable until cleared manually. I have fired over 50 shots with the SliXshot nipples with zero issues. These are fantastic!

Nice upgrade for my Uberti and Pietta guns

I replaced the nipples on my 1851 Colt Navy. They made the CCI #11 caps that I have work so much better. Their wrench is awesome too.
