I took most of it apart and wiped off all the gunky crud they shipped it in. I didn't take the trigger group out, might do that before I shoot it.
It looks very similar to my (long gone) Mossberg 930 SPX, but looks is where it ends. The SLP MK1 is way way way higher quality. The one thing I didn't particularly like is the weakness of the magazine tube spring. I'm sure it will feed fine. The trigger feels sweeeet. It’s really curved and is super comfortable, I'm positive it will make me shoot faster (kidding). I did notice the weight also. It is heavier than my Nova, can't compare it to a Benelli M2/4 but I would almost bet the SLP MK1 is heavier. When I took it down, all the weight is in the barrel.
The rail on top kinda obscures my field of view, I saw one guy on Enos that hack fu'd the hell out of his and took the top rail off. Don't think I'll be doing that. It looks good but seems unnecessary to me. I tried to put my TA44SR-10 ACOG on it but that didn't work, a LaRue mount doesn't work with a weaver rail and the cheek weld turned into a chin weld. I kinda wish I hadn't sold my Burris FastFire, doubt I would use it but I'd like to give it a try anyways. I like the fiber optic front sight although with my Benelli Nova I always hit high, sometimes over the steal. I blamed it on the FO sight, hopefully this won't repeat.
Its taking some getting used to as far as the weak hand load goes. I do notice the loading area is way smaller than my Benelli Nova and I now have an appreciation for the Nova's lifter staying up while reloading. I've seen guys smooth the loading port up and have the lifter welded so the forks won't puncture the thumb; for now I'm going to leave it be, I promise I'll post pics if my thumb gets forked and you all can say 'told ya so'. I have abnormally large thumbs so maybe they won't be able to fit in there too far and get hung.
It came with IC and Mod chokes, I'll probably put Mod in it and won't look back. It also came with two gas pistons, Heavy and Light. Most everybody I've talked to says that once the light piston is broke in, it will run with light Wal-Mart stuff and reduced recoil slugs and buck just fine.
I like it. Hopefully a range report by this weekend.
