If so, get one while you can. IMO one of the best Ruger has ever made. Gun has more quality than anything they are putting out now other than the American or 1911.
Yes, except for a few scattered around in local shops or on-line. Don't ignore the 9E, the budget version of the SR9. The internals and mags are identical to the SR9.
Sportsmans Warehouse, Bud's, online all have them at great prices @ $300 and under. From what I have read, Ruger is making them for distribution by Davidson.
