The only problems I have had with my FS 10mm and EAA are as follows:
1) I bought the gun brand new and took it out to shoot for the first time. It was great, more accurate than anything else I had bought up to that point and went through a 50 rd. box of weak Remington (UMC) 180 gr. pushing 1150 at the muzzle. That is, according to the Remington website. I was grouping so well and all the others shooting weaker rounds had stopped to hear the cannon roar, it was an indoor range, and watch me. Needless to say I blew through box 1, bought another and about halfway through the second box the rear sight flew off.
I contacted EAA and told them the problem and their reply was, "Send it back and we'll look at it." I then got a lecture on the hydraulic poundage used to push those sights into place and the "impossibility" of the sights coming off unless, as they insinuated, I had been pounding on the sights with something or put it into a pusher to try and remove or drift them, which I had done none of this. They also said that if I dropped the gun they could have come loose. I have never dropped it, and reminded whomever I was talking to, but probably Paul, about the little speech on hydraulic poundage and how recoil is probably more jarring than a fall.
They were nice and not sarcastic but the "We'll take a look" speech along with the veiled "It ws probably something you did not covered under warranty" speech did not make me feel good. They could have gotten the gun in the mail, declared that it was work not covered by warranty and then asked for crazy amounts of money to get it back. That or I would be out more money to get it shipped back with no fix. Anyway, I checked this board and found my case is not unique and I simply put them back on with a little JB Weld; they are fine now even with hotter loads. I have bought several things from Reed's Ammunition and research, great customer service and prices, and corresponded with them about my problems and they said this problem was so prevalent that EAA or Tanfoglio has started putting set screws in their rear sights to prevent this. Hydraulic poundage indeed!
2) Their customer service has never been rude but acts baffled whenever you have a problem, like it is the first time it has ever happened in recorded history. This board was a great resource before I bought the gun and I knew that some problems might occur, strange that no one at EAA has heard of them or reads this board since about 50% of the people on this board have had some problem with their pistols. I ordered some hi-cap mags for my 10mm and wood grip panels. They all came in the mail fine and the mags are fine but needed new springs. They inch up rather than spring up so sometimes the slide locks before a round can be chambered. That is not the issue. The grip panels came in a bag marked "EAA Witness FS .38 Super/.45 ACP."
I called and said that I had ordered the 10mm ones and they said that these will fit the 10mm, it's just not marked on the bags barcode tag. Well, I tried to put them on but the grip frame screw holes would not match up with those on the new grip panels. I could either seat the wood correctly and not screw them in or screw them in cock-eyed. Customer service said that these were the right grip panels but if they would not fit then send them back and they would send me out a new pair. I sent them in but they just refunded my money without consulting me or explaining why. I have always wanted to buy some from Hakan or Omega but they sell as soon as they are made. I guess I'll have to commission a pair.
