Don't forget the adjustable LPA sights. Sweet sights.
I beleive also that the SPX have a ported barrel.
Yes Bambi, it is an OKC M9. I bought mine yesterday and it's there.
Correct. I forgot that one.
The 500 SPX 51523 and 590A1 SPX 50771 have LPA sights.
The 500 Tactical Tri-Rail 50589 does not have LPS sights.
The 500 SPX 51523 and 590A1 SPX 50771 are ported.
The 500 SPX 51523 is also the ATI adjustable stock while the 590A1 SPX 50771 is not.
Are 14" barreled ones available?
