lvipscshooter Posted November 15, 2016 Share Posted November 15, 2016 I am wanting to play around in 3 gun. To not have to go out and buy a new pistol/rig/mags etc and keep the initial costs down (every pistol I have is Open division), I would like to turn my FN SLP MK 1 into a open division shotgun. It has a 22" barrel. What is the largest mag tube I can safely run on it? Any other tips would be appreciated. I do not have the $2k+ to invest in a box fed shotgun at this time, but could see one in my future Thanks Link to comment Share on other sites More sharing options...
ziebart Posted November 15, 2016 Share Posted November 15, 2016 Get whichever Nordic ext yields a total of 13 in the tube. Much longer than that and you'll have trouble with dump boxes and weak mag springs. Link to comment Share on other sites More sharing options...
gerritm Posted November 15, 2016 Share Posted November 15, 2016 I ran the Nordic extension with a pus 1 cap on my SX-3 and got 14 rounds and it worked with no problems. A couple of my shooting buddies run theirs with 14 and they also work. gerritm Link to comment Share on other sites More sharing options...
ziebart Posted November 15, 2016 Share Posted November 15, 2016 My 15 round tube had problems on my SX3. I also think shell surge may have broken the shell latch pin. That caused some problems as well. 14 may be a sweet spot. Link to comment Share on other sites More sharing options...
lvipscshooter Posted November 18, 2016 Author Share Posted November 18, 2016 Ok sorry to sound stupid but I gotta ask. so to get a 14 rd tube figuring the factory capacity is 8, I need a +6 tube kit? or do I need to buy a 8 & a 6 plus a coupler?

DocMedic Posted November 18, 2016 Share Posted November 18, 2016 When I first shot open I converted my FN SLP into a open shotgun, I ended up using a Xrail and Arredondo speedloader and tubes with a delta point rds. but I've ran a single tube that gave me 13 rounds without no issues with the Nordic tube spring Link to comment Share on other sites More sharing options...

Sorry that's not going to help you, my FN had to be modded to accept the Xrail which reduced the stock configuration to 5 shots. I use a +8 to achieve 13 Link to comment Share on other sites More sharing options...

ziebart Posted November 21, 2016 Share Posted November 21, 2016 I think stock the FN SLP has an extension on it already. You dont want to put an extension on an extension so the front has to come off first. My SX3 holds 4 stock so I got a plus 9. Link to comment Share on other sites More sharing options...
Woody3025 Posted December 9, 2016 Share Posted December 9, 2016 I have ran my SLP for years at 12 + 1 with no problem and my friend has shot his for the same at 14 + 1 all Nordic extensions. You can get them to run just fine with the right mag spring. Two downsides are that the 14 + 1 is cumbersome to maneuver and get into dump barrels sometimes. And the SLP has a shorter loading gate compared to some so the speed loaders are a little finicky. Other than that they will shoot anything u feed them.
