I've got the same one. Have ran about 500 rounds through it with only 2 FTE's (blaming cheap ammo). I also got the 5" barrel, but the slide was sticking bad with it. After a lot of filing of the sides of the barrel I finally got it working right. Was putting all 10 rounds within 1" group at 25' easily.
I have been reading about the recoil spring stove piping around 1000 rounds, so I called Phoenix today to order some more springs. I asked to purchase 3 springs, after I gave her my address info, she said they would be sending them out free of charge.
Wasn't my first good experience though. I ordered 3 extra magazines from them (much cheaper than the gun shop) and they sent me 4 as well as the holster. Checked my invoice and they only charged me for the 3 magazines.
p.s. I've done the magazine release mod, very worth doing. I did by an extra safety from Phoenix though to have on hand in case I ever needed to send it in for service or sell it.
