I just got mine (FN SLP Mk1). If it’s possible I may shorten my own stock, it’s too long for me too. I installed a 3gungear 8-shot side saddle and two shot forearm saddle. Rhino if yours doesn’t like light loads get the Browning Gold Sporting Clays piston, it’s runs on most anything (I think it’s made for 1-1/8oz or less loads).
My gun is a 3" magnum and came with both a light and heavy piston. Light is marked 1.5oz or lighter and heavy 1.5oz and heavier. My buddies SX2 2-3/4" only gun came with both and his is marked 1.25oz and lighter on the light one and 1.25oz or heavier on the heavy one. I stripped mine down and polished up all the areas I’m seeing internal finish wear internally with Flitz to smooth it up. I’m probably going to polish up the lifter as well, for me this gun is a lot easier to reload than a Remington or Benelli (and no Benelli thumb!).
I’m using two extended Briley chokes, a light modified and an improved cylinder.
I’ve heard of some people needing to replace the shell stop/bolt release spring with a heavier one (adds about three pounds more pressure). I’m not going to replace mine unless it gives me problems.

Some guys with SX2s are also replacing their recoil springs with ones from a 3.5" Browning Gold. Again, I’m not replacing mine unless it gives me problems. Like the Benelli the Gold/SX2/SLP likes oil too!
It’s a well used gun and I acquired it from someone I trust. He’s only used the “light” piston, even with some stout #field loads and slugs without issue. The gun works with pretty much everything.
Q: if I shoot heavier loads (I usually shoot #4 field loads, don’t know the weight), will I risk damaging the gun if I continue to use the light gas piston? Or is it just a matter of more felt recoil than if I used the heavy piston?
As far as modifications go, other than shortening the stock, I’m not going to change anything until I’ve put a few hundred rounds through it. If I have any problems (which I do not expect), I’ll revisit.
After doing some reading here and on other sites I decided I was going to purchase an SX2. This morning, a good friend tells me he found me a shotgun and to pick him up and he’ll take me to it. We ended up at a local pawn shop. Yes I was skeptical a first. However, my buddy knew the owner and comes out of the back room of the shop with a new unfired FN SLP Mark 1 with all the factory accessories in the box. I walked out the door (very quickly before the owner changed his mind) with it for $463.00. We immediately went to the range and tried a variety of ammo and so far I’m very impressed. Can’t wait to hit the range tomorrow and run some drills on the timer.
Will the SX2 MkI with 3" chambers function well with 2-3/4" low recoil tactical 00 loads? Or am I better staying with a guns with 2-3/4" chambers (I never shoot 3")?
