I’ve had a Uberti 1858 for over ten years now, and it was a fluke purchase because I liked the way it looked. So it sat on the shelf in a display stand for many years until one day I decided To try it out. So I got the items together and loaded up the cylinder, much to my surprise BP guns have quirks, and not every shot fired! After a few shots I was picking caps out of the stock nipples, and having a hell of a time. Off to the interwebs I went to figure out what went wrong. It didn’t take long to learn which caps and nipples to use. After receiving my order from Slixprings (extremely fast shipping by the way) I swapped them out and have had no problems since! This is a great upgrade for reliability and the stainless cleans up nicely after a fun day of plinking. If I ever get the stainless Buffalo 1858 I’ve got my eye on, this will be the first upgrade before I even load it. Thank you Slixprings for a much needed product and for being a veteran owned business. 🇺🇸

I recently put these on my Pietta 1861 Navy. They have worked well with the 4 different caps I've used. Including homemade caps. I will be buying these nipples for my 5 other bp revolvers. So far no cap jams either.

Good product good shipping

They reduce cap jams. They are well made. I ordered one wrong set and they were replaced with a minimum of inconvenience. Great service, great product.

I was disappointed in the nipples. 27 grains Goex FFFg. .454 ball. I was using CCI #11 caps. Although they produced good ignition, Every 3 of 5 shots blew the caps apart and jammed the revolver. I'm going to experiment and use some #10 caps (if I can find any).

Everything it's claimed to be. The little hole on the side is ingenious and blows away the spent fragments!!

I like them, they're exciting.
Work great.

After replacing the nipples on my 1860 Colt Army with the Slixshot nipples, I was very pleased with how the looked and their performance. I intend to do the same for my Ruger Old Army and to my Colt Dragoon. Thanks for a great product.

I like the fact that they are made out of Stainless Steel. Anything that helps eliminate cap jams is a good thing.

Great product! They cut way down on cap fouling instantly and hold the #11 caps much tighter that the factory nipples.

Perfect fit for CCI #11 ( the easiest to find). Quick delivery. Thanks for keeping black powder shooting fun!

Amazing product. Exactly as described. Definitely going to have to get more. And thank you for the amazing customer service.

Slix nipples stopped cap fragments falling into hammer slot in frame of my 1860 pony repros, jams reduced to near zero. Caps break up more completely than factory nipples so they fall free of cylinder during cycling. Fit of RWS pistol caps with new nipples is consistent and right neither loose nor too tight. Easy to seat caps fully, no “high riders to jam cylinder or cause mushrooms/ failure to fire.
Easy in and easy out for cleaning, where the stainless construction is also a plus.

Better than the originals.

100% reliable, consistent ignition. Clears caps with no jams. Installed a set of these nipples on my son’s ASM 1847 Walker. Worked great with CCI #11 Magnum caps and charges of Triple 7 powder.

Pressure vent holes are placed too far up the nipple when using CCI 11 caps (which its supposed to be good for), causing back pressure to vent into the side of the nipple and rupturimg it. Almost every shot results a cap jam, and it was like this for the whole set. Performs far worse then stock Pietta nipples

Reply from Slixprings:

If this was a problem we would have thousands and thousands of complaints of which we don’t. Read the reviews and you’ll see. Our cones have been engineered with the vent holes positioned in the proper location for optimal performance. The issue you are having is most likely from using older caps or the gun needs proper tuning.

What a difference! No cap jams! If you're new to cap and ball revolvers, this is a big deal! Get these!

I like em

The new nipples improved the reliability significantly. I haven't had a misfire since

These were recommended by an old pistolero. He was having many issues with the stock nipples that were factory issued. He was an avid shooter in local competition. I haven't fired them yet but I don't expect any issues.

I own a pietta and a uberti 1858. Put these on both. Work much better than the originals. Love the fact you can use #11 caps with them. Since that’s all it seems you can get right now. Easy to clean too.

Since switching to these, my caps (10 & 11) don’t fall off like they did. More consistent firing from my revolvers with out a misfire. I have them on all my revolvers and recommend them to anyone.

These nipples are a must for reliable BP revolver shooting

10 star product and service.

No issues easy install.

Having used Slixshot nipples on a 51 Navy I now install them routinely on all my purchases.
