Just scored a new 2014 SLP Competition and really like the overall feel of it. While I was waiting I read about shooting light loads and some issues so I ordered two Browning Sporting Clay Light Gold pistons, one from Midway which came in a labeled bag, and another from Midwest Gun Works, which came in a small envelope.

Now I took apart the SLP to check out the current piston and i'm dumbstruck. All three pistons look exactly the same. What am I missing. I'm going to be a tad upset if they are no different from each other after dropping $200 for pistons that "are for light loads" if they are no different from the new piston.


FN Piston is on left in all photos.

I would imagine the difference would be in the spring rate of each, but being the three you have pictured, all appear to have the springs marked in orange paint I would wonder. I would call FN to get the scoop, surely they would mark these with #'s as to identify them when the paint wares off. BTW, nice scatter gun !

I can't call FN as its a Browning part. I read in one place that the Sporting Clay Light Gold has only one set of holes.

Does anyone have a Browning Sporting Clay Light Gold piston they can take a photo of?

FN owns browning, so when you call FNH USA you will actually be talking to browning employees who also handle FN parts.

this is from an adendum from FNH

2. Gas Piston
The SLP Competition ships with a single, universal gas piston. FNH USA has recently updated the piston springs in the SLP shotguns. The result is a single piston that services all loads, 2 ¾” and 3”, 1 1/8th ounce to 1 5/8th ounce with a 24” barrel. This new universal piston is already installed in your SLP Competition Shotgun. It is identified with a gold rim on its base and is marked, “FN SLP 1 1/2oz and heavier.” Your FNH SLP Competition will function best with target loads intended for sporting and competition use such as 1 1/8th and 1 ¼ ounce loads.
Note that in Section 10, page 18 of your SLP Owner’s Manual, it references two pistons, one red for light loads and one black for heavy loads. These have been replaced by the single, universal Gold Rimmed piston. In Section 2, page 3, it also references two pistons. Two pistons are no longer needed and therefore not included.

Empty I understand that, but that isn't the issue at this point. Some people have had issues with the gold FN piston when shooting light loads so they purchased the Browning Sporting Clay Light load piston and its fixed the problem. I'm just wondering why the two Browning pistons I ordered look exactly the same.

They are the same. There is only one piston (gold rings) for Browning and Winchesters. This only applies to the gold rings.

This does not include the SLP 18". That has 2 pistons.

This all comes from barrel lengths and pressures.

It looks like yours are all the new gold rim pistons. You seem to want the lighter red rimmed piston that Emptybrass posted about. Good luck finding any old stock. Try gunbroker or call and of the dealers to see if they can verify if they have the red rimmed version.

I got a sporting clay light piston for MGW for my SLP mk1. The stock single piston has red marking paint on the spring. The one from MGW has orange paint on the spring. The piston from MGW will cycle lighter loads The stock FN stock has issues with them. Both pistons have the gold keeper. But there is a difference. At least for my SLP anyway. Usually springs with different rates are color coded differently.
