Got the kit today. Boy were the last few hours a crapfest, though not really the fault of the kit.
First I got out my new Vertec, only to find that the hammer wasn't falling all the way. I took it apart to find that the hammer spring was compressed and stuck on the hammer strut. I finally got it off and found that the strut was oversize, so much so that none of my many Beretta hammer springs fit it without binding up. Major bummer. Sent an email off to Beretta, then I took the hammer strut off my M9A1 so I could fit the trigger bar to the Vertec.
Now, the kind of fitting that the bar required is beyond what I've done before. I took my time, and attempted to follow the (rather useless) instructions on Wilson's website. About 2 hours of careful filing and assembling, then filing some more, then assembling, ad nauseum. I ended up with a pretty kick-ass single-action, but had accidentally filed way too much from the hammer support (I thought that that was the correct place to file to fix that issue, since that's what Wilson's website seemed to indicate, but I was just making it worse) and lost the DA almost completely.
The sad thing is, I love the SA pull and the DA pull up until the tip of the break is great (and I can make it work by pulling at a perfect angle, but not repeatably). I'll probably get another one someday but it'll be a while before I can afford to spend that much again. At least next time I'll know how to fit it perfectly. Since the Vertec was DOA, it'll be out of commission anyway until Beretta decides to send a functional hammer strut.
