"Must do" mods for the FN SLP Shotgun

Improving on the FNP™ Tactical, developed for the U.S. Joint Combat Pistol Program, the FNX™ Tactical was born and bred for battle. Like its legendary FN forefathers, this combat handgun was designed to not only survive the battlefield, but to emerge victorious.

My evaluation SC-1 arrived in a sturdy hard plastic case with four slide latches. One of the two models also features an adjustable comb.

What is it?

I purchased the FN SLP MK1 for home defense and as a fighting gun, so I won't be shooting anything besides buckshot and slugs in it anyways. I probably should have purchased it when the price was below $, but that's hind sight now.5/5(9).

This would drive a traditional shotgun shooter mad and over-tax their equipment. Thus, successful 3-Gun shotguns must handle a magazine tube full of a mix of birdshot, slugs and buckshot, being able to fire all three types of ammo at a time without jamming. The SLP Competition retains the gas operating system found throughout the SLP line along with the rifle-style synthetic stock and generously oversized handguard with extremely positive checkering.

New to this model is the vent rib that runs down the length of the inch-long barrel for dissipating heat mirage. We sent a box of birdshot downrange as fast as we could fire and reload, and this vent rib worked as well as one could hope. Also new is a flip-up rear leaf sight with graduated markings for helping get slugs to center-mass at longer ranges. There has been a move away from tactical-style sights on competition shotguns back towards the traditional- for-shotguns front bead which cannot properly be called a sight.

This has to do with field of view: The SLP Competition has such a bead, and the rear leaf sight folds forward into an opening on the vent rib, where it rides out of the way as you blast moving targets. If you want it to help you put slugs downrange or take down poppers, you can easily flip it up with the thumb of your support hand. Shotgun stages—indeed, whole matches—can be won through shotgun reloading speed.

To help them, the SLP Competition has an enlarged loading port, and the cartridge lift is milled so you can push your thumb into the magazine tube to seat the last cartridge, and retrieve your thumb again without snagging yourself. These details are absolutely crucial to a modern 3-Gun shotgun, and work wonderfully on the SLP Competition. But how does it shoot? Testing began at the trap and skeet range, where the SLP Competition came up to bear like a dream and tracked targets smoothly.

The SLP strikes many balances. Lightweight shotguns kick like mules, which slows down follow-up shots. Allen wrenches are included for adjusting the comb, assuming you have the blue or black model. The wood is laminated and available in black, blue and green color shades. The evaluation model shown here is the black version, and I would describe the color palette as black-grey-brown. The pistol grip is full and aggressively angled towards the vertical.

Gripping the stock with my left hand, I can definitely feel the difference. Loosen two Allen screws on the right side of the comb and you can raise and lower the comb to your preference.

The same included Allen wrench is used to loosen two lugs the extend vertically from the main stock body. Once these are loosened, you can move each lug to the right and left independently. Move the whole comb right or left or angle it in either direction to your preference. The SC-1 is available with 28 or inch barrels. My sample shotgun came with the inch barrels, and this was fine with me. For a competition shotgun, I like the extra length and the swing inertia that longer barrels provide.

The barrels are back bored to smooth out recoil and help ensure pattern uniformity. The barrels are also fully chrome lined for the entire length. The chrome lining makes cleaning a bit easier and will add the life and corrosion resistance of the barrels. The sample SC-1 in this article arrived with a total of five choke tubes: The choke tubes are extended and have a knurled exterior surface, so they are easily installed, removed, tightened and checked with fingers only.

The nice thing about Invector Plus tubes is the broad availability Browning and aftermarket choke solutions. In addition to the tubes mentioned here, you can obtain Light Modified and Improved Modified direct from Browning.

For example, you can get Invector Plus tubes in flush fitting format, ported chokes and even helix chokes that impart spin on the shot column, thereby causing some pellets to move outside the pattern.

Figure out what you want to do, and then go shopping. The included choke wrench features a sliding lever. You can crank it to one side if you need some extra leverage to remove a gunked-in choke tube.

Safe and fire modes are selected with forward fire and rearward safe movement of the sliding switch. Side to side motion selects which barrel fires first with the single trigger. The trigger is adjustable back and forth so you can make fine adjustments to the length of pull without monkeying around with the stock or butt pads.

A small allen screw is located on the very top of the trigger face. Simply put the big convex curve of the receiver together with the big concave curve of the forend and the two pieces snap together as if attracted by magnets.

I had a number of different shooters use this gun with hand size ranging from medium to extra-large, and there were no complaints about the pistol grip area being too full. The weight certainly contributes to that, and the ported barrels do an excellent job of mitigating felt recoil.

Recoil force is recoil force, but the weight and porting make it feel less than it is. The standard recoil pad is effective as is. Unlike most other shotguns I have in the safe, this one would not need to be swapped for an aftermarket model.

I normally default to single shots from the bottom barrel, so the recoil impulse is more in line with my body. Just for kicks, I shot a round of trap with the upper barrel only, and I could detect no difference at all in felt recoil or muzzle flip. Here's a comparison of the factory lifter and the modified lifter Factory on the bottom and modified on the top 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 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. 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 All the work I put into it is just to make it fit me and work better for me. In the rounds I've put through it in the last 8 months, I can truthfully say I have only had 3 malfunctions. 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. 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 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.
