Caimlas let me try to help you "cooling down"....
I had the same experience, I was drooling over a Witness in 10 mm Auto and I could not believe the price..after all Tanfoglio has a very good reputation internationally.
So my wife bought me one for Christmas.
Had FTF and FTE issues from the start and with different ammo..tried lot of things, changed mag spring, recoil spring, tinkering with the magazine lips.
The feed ramp was perfectly polished, no burrs in the chamber...improved a bit but still high failure frequency, I could not get through one mag without problems.
EAA customer service is very poor, to say the least, you have to pay for shipping to and from (even Hi-Point pays for shipping back).
And I heard that people sent back their pistols back several times without the issues being resolved..someone paid in shipping charges more than the price of the handgun.
Specific problems for the 10 mm version:
Customer service is vague about what kind of ammo you can use, they told me more than once, categorically, NO to Double Tap, Buffalobore or Corbon...I wonder why, these loads are within SAAMI specs.
Seems they want you to use "soft" 10 mm loads, basically at 40 S&W level..so what's the point of owning a 10 mm???
The newer Witness (at least the standard model) have the new "rounded top" style slide and I heard from more than one source about cracked slides for the 10 mm.
To sum it up, even if I loved the look and balance of the pistol, I traded it for this (S&W 29 in .44 Magnum) and never looked back
Would I buy one again?? In a heartbeat if they make the rounded top slides stronger and I can count on a decent Customer Service..I think Tanfoglio should get rid of EAA and I been tempted to call them directly in Italy to report the problems.
I hope this helps.
P.S.
If you buy the 10 mm or the 45 ACP you can convert all the way down to .40 S&W, 38 Super, 9 mm and 22 LR.
If you buy a 40, a 9 mm or a 38 Super you can only convert between them and the 22 LR
Each conversion kit costs $229
Pricewise and for convertibility purposes, the best deal is if you can get the 45/22 combo with blued finishing
