Thread: Any Issue Taking a SCD Apart?

    I have a few pistols done with CPII... PX4 (had two done; sold the .45, still have the 9mm), Glock 30S, and Ruger LCP. Never had any issue with slickness. Had magazines and Garand clips done, as well as small parts of a half dozen other firearms (barrels, controls, charging handles, bolts). No issues thus far... and have been using CCR since 2005ish. Started CPII on guns in either 2009 or 2010.

    While NP3 and other similar finishes are self-lubricating... it is far from an oiled gun part. Parts that have serrations, like the rear of slides, still function the same. Used the Glock with sweaty hands, and no problem. If I had a grip issue with a CPII coated firearm, Id say I probably would have the same issue with the stock finish.

    I cant see an issue arising, especially with the serrations on the back of the SCD, but either way, will post about the end result. If it doesnt work out, the plated one will be filed away (looking at the circular filing cabinet next to my desk)... and will order a new SCD (non-blem).
    CP2 is Nickel Boron (judging by the description on their website). This means coating thickness is most likely closer to .005" (BIG difference from .0005"). Double check to make sure that that thickness is not an issue.

    Step ahead of you...

    Its been a while since I looked into the technical stuff behind it, but want to say 0.0007 or 0.0008 was the numbers I remember. Could very well be 0.007 or 0.008, but looking to get verification.

    Robar accidentally did the slide of a Glock in NP3. Makes manipulations more difficult for me.

    KC Jones is the big plating company for Nickel Boron. I'm sorry, but if they quote .005" for thickness (and do a shit load of guns) that is probably the industry standard for the coating. Every nickel teflon coating company quotes .0001-.0005". That is the minimum to the max. The notion that this company could cut that number in half (for the same finish) just isn't possible at the quoted prices. The price difference arises from the environmental fees (Nickel Teflon incurs serious fees due to chemicals used in the process to plate... I know, because I pay them on a regular basis) and the amount of time involved in NP3 coating (27+ hours from start to finish).

    Would 0.005 be an issue? Figured Id ask both sides.

    I will flat out say I have no clue. I know how it affects parts like slides and barrels, not something like a roll pin in a part. I will say, I would not coat parts in anything that added over .0005" in plating thickness (because NP3 has been shown to be a good coating for firearms over the last couple decades). The fad of eco friendly nickel Boron has come about in the last 5 years. Will it effect a factory Glock slide or Glock barrel? Probably not.

    After owning and shooting everything from Ruger SP-101 revolvers to Glock pistols to 1911-pattern guns finished in NP3, I agree with this. NP3 shines for internals and for things like the SCD where the user is just applying pressure normal to the finished surface. When using serrations, NP3 makes getting a solid grasp on the slide more difficult. "Colt-style" narrow-pitch 1911 serrations are less impacted by the finish than the wider Glock-style serrations. I believe this is due to the sharper serrations of the 1911, not the pitch. The more the grasping surface shreds skin, the better it is with NP3. Checkered NP3 front straps are awesome, serrated front straps are not so awesome.

    The finish build up for NP3 from Robar for firearms is around 0.0005". It can be plated in other thicknesses from about 0.0001" to 0.0050" in accordance with one of the industry (aerospace and automotive) standards. Robar is the firearms facing side while Coating Technologies, Inc. is the mass production aerospace/automotive side of the same business.

    Back in the late 1990s, Robar once plated the bore of a P7M8 for me. The pistol was safe to fire as the buildup was minimal, but there is a reason (time drove costs) why Robar does not plate barrel bores now.

    I would have no concerns about plating NP3 onto a SCD. I may include a few of the "blems" in my next order and see what happens.

    Thanks for the heads up. Will see what the verdict is from CCR.

    Any Issue Taking a SCD Apart?

    Well, figured Id update this post, since I got a package from CCR today...





    Now, I had a few smaller parts to send in for plating, and since I was busy with a few other things, I sent it with a note. Got it back, and works/fits just like the blem SCD did prior to the plating on my 30S. Didnt get any info on CPII.

    Liking the finish, and isnt slippery to the point where use will be questionable. Installed it, went to the gym, and while I was still a little sweaty, I tried activating the SCD (pulling the trigger with thumb on backplate; obviously on a cleared gun). No issues, so Im happy with it. Even more happy that I didnt have to buy a new SCD. [emoji106]
