I recently got a Pietta 51 Navy. My #11 caps which are all I could find would stay on the nipples. I swapped them out for Slixshots which worked perfectly.

I have 6 percussion revolvers with slix nipples in them. All perform flawlessly.

These nipples worked great in my Ruger old army revolver. Solved my issues with the original nipples. Definitely will buy again

My second set. I have 2 black powder revolvers and purchased a set for both. Easy to install and makes shooting a lot more fun. Highly recommend.

Replaced all my BP revolver nipples with these and virtually eliminated "fall offs" and debris jams.They are for real as cap problem solvers.

Very happy with them on my Pietta 1858. No more problems with CCI No. 11s running away.

Great fit for caps and consistent firing. Easy to install and clean. I'm very satisfied.

My order arrived sooner than anticipated. That evening I replaced the original nipples on my 1851 Navy Colt. Perfect precision and work great.

OUTSTANDING customer service. I ended up having a 1858 Lyman/Uberti pistol that did not use standard Uberti style powder nipples. Patrick worked with me to isolate just what I had and sent me what I needed. Thanks again Patrick!!!

I do not feel hampered by carrying a percussion pistol afield making sure it is one which is as totally reliable as possible first. There is no guarantee of 100% reliability even with cartridge firing revolvers, however there are several things which can be done to make our cap and ball revolver as reliable as possible. I purchased one of the first Ruger Old Armies way back in 1972. It would be difficult to find any percussion pistol more reliable than this one. It served me for over 40 years with never a problem. However, about five years ago when I was getting ready to shoot this particular old Army in the Idaho State & Territorial Muzzleloader Match I started getting misfires. The Old Army was originally designed to allow it to be dry-fired. That is without a cap on the nipple this Ruger was built with such precision that the firing pin on the hammer did not contact the nipple unless there was percussion cap in between. Over the many years I used it either the nipples had become worn, which I doubt, or caps were now thinner than they used to be. The solution was to replace the nipples with aftermarket, high quality stainless steel ones. That modification was enough for the Old Army to take first place.

Now it is my routine to automatically replace the factory nipples on any new percussion revolver which comes into my hands. These stainless steel Slix-Shots as they are called come from SliXprings. They are shaped differently than the factory nipples, which are also called cones, and they have a smaller charge hole as well as a small vent hole on the side. They are made to accept #10 Remington or #11 CCI percussion caps. Pietta and Uberti nipples have different thread patterns so replacement nipples must be ordered for the specific brand. These high quality nipples sell for $36 for a complete set of six for most sixguns except replica Walker and Dragoon nipples are
$40 and the five-shot pocket pistols nipples are slightly different and currently run $30 for a set. These are the prices as this is written, however inflation seems to be running rampant now.

With the original factory cones, caps will often be found to be too tight which means they don’t seat properly and this can cause misfires, or they are too lose and fall off the nipple when the sixgun is fired. The Slix-Shots are made to fit as perfectly as possible. One of the problems with shooting percussion pistols is cap jams, that is a fired percussion cap comes off the nipple falls into the action and prevents cocking the hammer and/or firing the next chamber.
One of the causes of this is hammer blowback. This means when the pistol is fired pressure blows the hammer back far enough to allow the cap to split and fall into the action. The main way to prevent this is to install these quality nipples. There are three other things which can aid this also. First make sure the face of the hammer is smooth with no burrs to grab spent percussion caps and pull them off the nipple when the hammer is cocked for the next shot.
The face of Remington hammers are solid but it is a good idea to check them and make sure they are smooth using emery paper or a file if they are not. The Colt hammers can be a larger problem as they have an opening at the base which contacts the safety pin on the back of the cylinder. This opening slot needs to be checked carefully and any burrs or sharp edges removed.

The description says CCI #11 fit. The nipples are to big. CCI #11 required extra pressure to fit on the nipples. Some only fire on the second strike, indicating that the caps are not completely seated. I like the design of the nipples, quality control is lacking.

Reply from Slixprings:

Sorry to hear they didn’t perform for you. The problem is not the nipples as these are made on high quality CNC machines and our tolerances are exact. The issue is the quality or age of the caps you are using. We’ve seen this before with Older CCI #11 caps. Get some New caps and this problem will go away. The other issue might be your cylinder to barrel gap is too big or your hammer spring is too light. More than likely though it's the older caps you are using.

I got these cones and used them with CCI #11 caps and they worked perfect every time. No longer do i have misfires. great product well worth it. thnks

I liked them so much on my 1858 Remmington that I added them to my Colt Army and Colt Walker. They made a huge difference with cap jams, much better.

I wanted to say that the nipple wrench they make is the best one I could find. I have several and this one is the best fit. I have not used the nipples yet but they are made very well.

I replaced my Pietta Remington 58 nipples with Slixshot nipples when I used #11 cap . There is no more caps falling out, no need to pinch the caps to fit and no need to worry about chainfire from improperly seal caps. Great product, highly recommended

Brand new to black powder shooting. Caps are hard to find. All I was able to get were CCI #10s. Had a hard time getting them seated on the factory nipples. I'd get FTF about once per cylinder. Switched both revolvers out to SliXshot nipples and have had no problem. I have a Uberti G&G in route and I've already ordered a set to change out immediately. Why bother with the headache? This is a simple and effective solution.

I will say I believe these Nipples are the best. I have 14 cylinders and 1 Pepper Box. And they are all fitted with Slixshot Nipples. Cap Jam has been reduced to Almost Zero. I won’t even think about loading a new cylinder until I have put my Slixshot Nipples in. I have 4 more Cylinders on back Order. And yes I will be Ordering 4 more set’s of Nipples. Thank you Slixsprings. Sincerely Tom Simmons

Bought slix nipples for ny 1851 colt 1858 Remington and my dragoon too cocked to shoot installed easily excited to try them and the slix hand also

SliXshot nipples fit both the caps and the revolvers I use perfectly. Caps stay put and cylinder jams just don't happen any more.

Installed these nipples on Pietta Remington. After several cylinders fired, no misfires or cap jams. This also improved ignition which helped accuracy.

These arrived in perfect shape

My second order and they work as well as the first. Excellent product and very fast service.

These are great!

Hello reader, Cowboy Gun here. If you're slightly on the fence about purchasing these Slixshot nips I would suggest you pull the trigger already! I purchased 2 sets of Slixshots for myself and my girlfriends 1858 carbines. She just loves her new nipples! We had no cap jams to memory and prior to using these nipples my 58 was about enough to make this cowboy throw that humdinger in the river! Very important to use the recommended caps as shorter caps may cause a chainfire. Also make sure to give a touch of antiseize to each nipple when installing. I just know you'll love these new nips as much as we do. I would also note these are not just shiny new bling to make your 6 Gun more pretty. The flash holes are wider and the cap cone end protrudes further toward your hammer. If your having ignition issues from hammer not hitting cap hard enough this will solve that issue. Before these nipples my Gun was nothing more than a club against those black bears or wildcats. Now I'm confident it will go bang everytime! So how about it partner? Help this Veteran owned business today. You'll be sitting high in the saddle with the confidence she'll go bang when needed.

I can't give 5 stars for the product because I haven't had a chance to shoot the pistol. But they did go on good and seem to hold the caps good so I'm sure they'll be great. Fast shipping and easy to order on the website
