For those looking to jumpstart their experience with their SLP shotgun, I've got some suggestions after I've had mine for some time now.... I started out with the typical factory gun and jumped on a few times that i felt were needed right away. This items include the Nordic Compoents extended bolt handle and bolt release. To me these items were no brainers. They were easily better than the stock setup and not too expensive. The bolt release says it's for a Benelli, but just ignore that and install it on your FN without worrying about a thing. What you end up with is this setup....

After those basic items, I would suggest an efficient loading system. I had initially started out with the typical California Competition Works 4 round shot shell holders. They were great. I could hold a ton of shells on my belt and load them okay. Unfortunately I was never that fast with weak hand reloading and when it was really cold... Like below 30 degrees, I would drop a ton of shells and look like a total ass trying to load. Thankfully I had started working with Mark from Carbon Arms. Mark is heading up with Colorado State Multi Gun Championship match that is happening in April of this year, and I'm doing the website for the match. It just so happens that Mark is the maker of what is the baddest shotgun loading system on the market today!!! The TWinS Shotgun Loading System allows you to grab two shells at a time and load them into the shotgun. For me, this has proved to be significantly faster than weak hand reloading.

I ended up with a SSL Backbone, SSL Pinwheel, and the SSL Chest Rig as my complete loading system... This system allowed me to reducing my shoot 1, load 4, shoot 1 time by 15% immediately. This is without any practice... I ran several runs on the shot timer with the weak hand reload and then ran the Carbon Arms system for the first time after setting up the system... It was an instant 15% decrease in the overall time. I was amazed and sold on the system!

Up until this time, I had always treated the shotgun like a 3rd wheel... I've always been a big fan of pistol shooting and I enjoy shooting rifle so training for those have been easy. The shotgun has been the red headed stepchild... Now it's a primary part of my training and match shooting....



The next thing I jumped on came out of a class that James and Mark from Carbon Arms taught regarding Multi-Gun matches... A +1 tube on the SLP Mk1 is legal in most matches. It hadn't dawned on me before, but with the TWinS loading system, you are always loading two shells at a time. Well if you shoot to bolt lock, you will grab two shells from your loading system and drop one into the ejection port, and then load the next one into the loading tube. This sets you up for having an odd number of shells loaded. This becomes a problem since you're loading 2 at a time. So adding a +1 Nordic Extension turns your 8 round mag tube into a 9 round mag tube and you're back in business. Being that I shoot tactical, I need to make sure I only load 8 round in the tube at the start of the stage, but after that start, it's game on. Load up to 9 round in the tube and you're all set.

After setting up for the +1 extension, I realized that some speed could be picked up by being able to load the round faster. This is accomplished by a couple of things... First having your lifter welded up so the pitch fork is gone and there is a smooth ramp into the mag tube... The factory lifter, is forked in order to cradle the round going into the chamber. Unfortunately this is a pinch point when loading and not the smoothest ramp when trying to load quickly. Here's a comparison of the factory lifter and the modified lifter.... Factory on the bottom and modified on the top...

I sent my lifter off theC-Rums to have it welded up and extended for smooth loading of shells. The work took about a month to ship and return, but it was well worth the time and money. Loading is smooth, fast and pinch free now.

This loading system was also improved by attacking the receiver with the Dremel. Normally I'm not a Dremel type of guy, but I didn't want to pay a gunsmith to open my loading port, so I did it myself. The opening of the loading port is most important in the front of the port, which allows you to seat the loaded shells into the mag tub quickly without having to shove them forward past the shell retainer. As you can see from the photos, there has been some significant material removed to ease the loading process...

You can also see from the photos the that I needed to cut back the hand guard in order to make room for the cuts into the receiver and for the loading thumb not to be impeded during the loading process....

More to come...

The next thing I decided to work on was the length of pull of the stock. I initially found the stock WAY to long.... Well maybe about 1" too long. This was adjusted with some work today. I posted a detailed write up on how to make this change in another post here on the forum. Here's the detailed info...



Last but not least, I decided to ditch the optic rail. Knowing that I will never shoot in Open class, I knew I would never use the optic rails on the FN SLP so I grabbed the angle grinder, installed a cutting wheel and started cutting. This removed about 4 oz from the gun and turned the useless rail into what mimics the rear sight on a pistol. The sight picture is exactly the same as you would expect from your pistol. Due to my loading system, I also choose to flip the gun over in my strong hand and load with my weak hand. This cut off optic mount also serves as a hand stop when I flip the gun over for loading. I may remove more in the future, but this was my starting point...

Here's a shot of my finished product....

This is one of the few guns I have that I can say is totally and completely reliable out of the box. All the work I put into it is just to make it fit me and work better for me. In the 1000 rounds I've put through it in the last 8 months, I can truthfully say I have only had 3 malfunctions. 2 failures to feed and one failure to kick a round from the mag tube. All failures were resolved by working the bolt handle. For a semi-auto shotgun I consider this to be really good. Things keep improving as I get more rounds through it, so I'm not concerned one bit about the few malfunctions I have had.

If you have any questions, please let me know.
 
Im curious what chokes you are using, Im guessing briley, I have almost all the same things done to my SLP minus the mag button but that will be remedied shortly. I also left the stock at its normal LOP, Im about 6' and have long arms so it doesnt bother me too bad. Im glad to see someone not running a benelli, thought me and scott hearn were the only ones...
 
The choke you see in the photo is the FN branded LM from MidwayUSA. It was the same price as the others and I was buying some stuff from Midway so I thought I would grab that one. Otherwise I've been using the factory chokes. I'm still getting a feel for the pattern and what I can do with the gun. I settled on the Winchester Universal 7.5 shot as my primary birdshot and I just got that new choke so I won't be very useful in making suggestions on what choke to choose.

I shoot left handed and I went with the Winchester ammo because it blows the least amount of crap on my face and glasses. The Federal stuff from Walmart totally covers me in blowback flakes of junk when it ejects.
 
I would have to say the SLP is running about even up here with Benelli. Of those running dedicated competition guns it's about half Benelli and half SLP around here. There are a lot of shorter "tactical" style Remington's and Mossbergs at the local matches. I've yet to see any nice trick out competition 930 based comp guns.
 
Yea I'm cheap and the CZ has been treating me well! I got another one from Tony and plan to keep track of the little things to get one 3 gun ready, cool thing is when your done with the CZ you still have some cash left over for important things like beer and cigars LOL

Good write-up! it's nice to see people thinking outside the box cause well lets face it some folks don't have Benelli money! Later,

These pics ain't great but this is the "AI package" on my SLP. It loads a crap ton better than it did.

I think Mike said he added some pvc pipe to the hand guard. These pics look worse than it does in person. Did I say it loads good?

I really like how open that loading port is now...mines big but not that big...
 
I created an account JUST to say thanks for this thread! really cool. I purchased my first semi-auto shotgun today, the FN SLP Mk 1. I'm currently scouring reputable websites to find the nordic charging handle in stock for sale, and I also plan on doing the nordic bolt release button mod.

You are one brave hombre to dremel for the enlarged loading port, sir!
