Does anyone know what brand or style of snap cap is the best for protecting firing pins? I have some that are spring loaded with a brass striking spot and some that have a plastic striking spot (which dented shortly after they were put into service).

My guess is that the spring loaded variety offers the best protection- I need to buy a few pair and would appreciate your: Opinions? Brand preferences?

Thanks, Jim

All I know is that my double gunsmith is adamant I do not use the heavy brass nickel plated snap caps because they put too much strain on the ejectors due to their weight.

De-prime some old hulls, Purchase some red gasket silicone. Fill in the primer pockets and let dry. The silicone is flexible enough not to leave any impressions yet resilient enough so the pins are not damaged. I like the red colour. When I open the gun I immediately know I have snap caps in it and not a loaded shell.

No, they are not.
The clear plastic two color ones are prone to having the rim snap off with ejectors.
The brass spring loaded primer on some of the short red aluminum ones is too soft and dents too deeply too fast.
The A-Zoom aluminum ones with the elastomeric primers seem to work well.
The chrome plated hollow brass ones are next to the best in my opinion. I don't see how the weight is straining the ejectors too much as I have never had a hint of an issue in 25 years or so.
The best I have ever had were some older solid red plastic ones with an elastomeric "primer". I don't remember who made them or where I got them. I also have some old solid black plastic ones with no separate primer that sill work but the rim "looks" weak. They looked weak when I got them 25 years ago.

Joe, I agree with your gunsmith, at least in theory. I've not had a bad experience with heavy snap caps simply because I won't use them. Any mechanical "train" anticipates some movement/flex/give unless it is specifically designed for a solid, no give blow. I doubt that the ejectors were designed with no such a heavy load on the business end.

Just my opinion.

I use nothing but A-Zooms in all my shotguns, from SxS's to O/U's and even on my autos. Never had a problem with them.

Jack Rowe liked my A-Zoom snap caps.



I am glad to be here.

I've made some dandy snap caps for my rifles by drilling and tapping them to 1/4" NC and threading in nylon screws from the hardware store from the inside . As they wear they can be screwed out further and trimmed off. With your 209 primers you might need a bigger size hole/screw?
I'd think that shotty gun shells would work this way as well.

A-Zoom- hands down!! Keep them in all my LC Smith guns when they are not being used on a daily basis.

I've had rims break on clear plastic snap caps. Haven't had a problem with the nickel plated, but I like these better.
