So I really want a new shotgun and the 1301 seems to have what I want out of the box.  I have not shot one hey, and may not have a chance unless I buy one.  What's the big dif between this and the FN?  I know people are gonna say m2, but unless you are adding the extra $$$ ......hush.

The FN SLPs are falling out of favor in the 3 gun community, very few are using them compared to a few years ago.  For more info on the 1301, check out this thread on the BE forums: http://www.brianenos.com/forums/index.php?showtopic=179930

I am very happy with mine.

They are light and fast. The guys I know that shoot them like them.

The extension tube for a nova fits?  How many chokes do they come with?

They come with a flush IC. I bought a few extended Brailey chokes plus the Brailey wrench

Best thing I have bought for 3gun!  Had mine a year with no issues.  I have two MXT tubes,  one holds 10 and the other 14.  Did the port job myself In Feb and I wish I would have done it last year when I bought it! Would have saved me a bunch of time over the matches.  Had it over a year and after about 2000 rounds maybe,... only cleaned twice.  Shot four matches since the last time I cleaned it, that's including the first Versa Max Shotgun match in Feb.   Probly one of the best gun purchases Ive ever done.
