As many others have said, ”I put them on everything”.
These are especially important on the pocket revolvers. These little rascals are notorious for cap jams. I’m not going to say everything is unicorn piss, fairy poop and rainbows, but it’s better. I can get thru a couple of cylinder-fulls with out major jamage.
On my ‘51 navy, caps needed a squeeze before putting ‘em on the nipple. None of that mule poop now. What a change. A few revolvers is all I need caps on, rock lochs from Jim Kibler for long guns.

I have never had a problem with any product I purchased from Slixshot. I've used them now on 2 pistols I'm restoring and the nipple wrench is the best I have.

I replaced the original nipples for a Pietta 1863 pocket Remington revolver with the Slix Shot nipples. Number 11 CCI caps fit much better and the cylinder to frame cap jams are much reduced. The caps remain in place with no need to "pinch", so, I can use my in-line capper while loading. The capping cutout in the pistol frame is very small which makes my fat arthritic fingers really like the new nipples.

Quality products and a must upgrade for your black powder revolvers! I’ve ordered two times now and will continue to in the future.

Everyone should know that Slixshot nipples are great for their Walker/Dragoon-sized reproductions to the 1851 Navies - and everything in between. But they are also great for your pocket models!

Replaced original nipples on 1862 Colt repro due to unreliable fire. The Slix Shot nipples corrected the reliability and reduced the number of cap jams. I intend to replace the nipples on my 1849 pocket Colt.

This nipples are a huge upgrade from factory. They fire every time when new caps are used. Highly recommend.

put these in my 1862 pocket police and it cured my cap jam problem

Works great. Eliminate 90% of cap jams.

I have bought parts from these folks their prices are more than fair and their parts First Class I have had zero problems with their products.

Well made and designed, very consistent nipple to nipple
Works well

I have these on my Uberti Pocket Navy and Pocket Police models, but they also thread onto a Signature Series (3rd Generation Colt) Trapper's Model as well.
They do an excellent job of staying on the nipple preventing jams and cap sucking so prevalent with Colt replicas.

as always...timely service and quality products

Glad to have Slixshot cones available for the smaller “pockets” now. Thank you !

These work great on Uberti replicas!
Colt hammers have a habit of biting the primers and pulling them off the nipples even if you file the points off them, and these nipples keep the primers from falling off into the action of the gun. Great improvement!! I have put them on a Colt 3rd Generation Signature series 1862 Pocket Police (Trapper's model) as well, and they will work although the threading is a little testy. Be sure to use lube on the threads.

I have over a dozen cap & ball revolvers and they all have your nipples.. I just bought the '49 pocket revolver and was glad to see you had your nipples for it.. thanks..

Work great look great. Zero cap lockups since changed. Fast shipping too.

Definately an improvement over the stock cones!!!

Look good but have not used them yet

These nipples are a high quality nipple. I have less miss fires and the caps remove easily.

Completely stopped cap jams!

installation on some older uberti 1849's causes problems because the cap well cut out is not cut as deep as later models. this makes capping the revolver impossible due to the contour of the nipples. The nipples themselves are very well made with a nice "small" flash hole.

This can occasionally be an issue, but it is very rare.

The nipples are slightly longer than the originals just enough the the cylinder would not rotate, I removed them

Follow-up from Dennis — 4/28/2025:

Can’t say enough about the customer service. Patrick is beyond a stand-up guy. I ordered nipples for a Uberti Pocket Model, but they were too long. I mentioned this in a review, and before I knew it, Patrick told me shorter ones were available and sent me five to try. I haven’t tried them yet, but I hope to this week and am confident they will work. As stated before, fantastic customer support.

The shipping was fast. As soon as I get a new revolver, I order a set of SliXshot nipples. These nipples were easy to install. I am happy with my purchase.

Unfortunately, I still had frequent cap jams. I’ll take a look at the main spring.

Reply from SliXprings:

A mainspring that is too light, excessive pressure, or the wrong caps can cause this issue.
