2017 RAMI BD 500+ Round Update (grips, peening, etc.)

[MattyD380]

Right off the bat... zero malfunctions of any kind, since the very first mag I put through it. The gun has been flawlessly reliable, and unbelievably accurate.



That main group is 75ish rounds, at 10 yards. It shoots right up there with the guns I typically shoot best (Beretta 92c, Beretta PX4c, Smith 6904). Love the way it handles, love the way it feels.

Here's a pic with the wood grips I've been using:



The checkering is fairly aggressive and gives you an excellent hold--better than the stock grips. I definitely recommend them.

And here's the ebay link, if you're interested: https://www.ebay.com/itm/CZ-2075D-RAMI-CZ-2075D-PCR-French-Walnut-FULLY-Checkered-Pistol-Grips-w-Logo-NEW/262624764948?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

I also put the Pearce pinky extension on mine (not shown in the pic). Feels great. I think it helps improve control, ever so slightly.

Barrel Hood Peening?

I don't think it is--or, at least to the point where it's a problem. But the recent post about this issue on a 2017 rami had me a little concerned. There's finish loss on that ledge, but I don't see that the metal is deformed:



However, this corner has taken more of a beating:



The metal is smoothed and rounded... but doesn't seem like it's anything to worry about. Thoughts?

Things I don't like?

Only one thing: the grip screws. They come loose. And the bushings/sleeves are "free rotating." Nothing some loctite can't fix... but, I had to take a screwdriver to the range and keep tightening down the screws. And since the bushings are aren't locked in place, I'll have to loctite them first (already did one). Then loctite the screws into the bushings. Never had to deal with that on a gun.

UPDATE: I used a new image hosting site. Hopefully this works. Sorry for the broken pics.

Have you tried rubber o-rings on the grip screws? Those always work for me.

You should use loctite to secure bushings and then use rubber o'rings to tighten the grips but no locktite on grip screws, otherwise, you will not be able to remove the grips.

Might consider vibra tite for grip screws. I believe amazon carriers. You can remove loctite, but might take heat. Link

For peening to occur, the contact area between the barrel and slide must be small so that the pressure is greater than the strength of the material.  (Impact forces included).  As peening gets worse, the contact area is enlarged.  If the fit of the parts is not too bad, the contact area will soon be large enough so the material strength will be adequate and peening will stop, or at least slow to the point it is no longer an issue.  If the initial fit of the parts is sloppy enough, this esplanation will be of no value.

Thanks for the feedback, guys. And sorry for the broken picture links. I think they should work now.

That's a good thought on the rubber O-rings. The Wilson/VZ grips for my 92c came with rubber O-rings--never had a problem with those coming out. And I think the idea of loctite-ing the bushings, but securing the screws with O-rings makes sense. I'll also look into the Vibratite.

As far as the peening...

Frogwalking, thanks for the description. Makes sense, that strength/pressure have to find some kind of mutual equilibrium. I think that's what's meant by "self limiting"? That corner on my barrel definitely shows some smoothing. But I don't think it was any worse in the last 200 or so rounds? I'll keep an eye on it.

Thanks again.
