Call Ernie....
FireintheHole,
If you wnat to know what parts you should have "pre assembled" to keep your BERETTA 92 running, just go back to the LTT site, get Ernie Langdon's number[or email] , and ASK HIM. He is Da Man on '92's. I asked him the same question, and he fixed me up. Let him do the same for you.....
