    Default HK locking pieces

    HK makes five different locking pieces, ALL with a 40 degree angle: #1, #9, #19, #23T, and #30T. Why so many? Isn't 40 degrees always equal to 40 degrees? I understand that the 23T and the 30T are HARDENED steel (NOT Titanium as some claim), so I see that they are different. But, why two hardened locking pieces with identical 40 degree angles, and three standard locking pieces, all with identical 40 degree angles?

    19 is for the PSG1, which uses 1/2 moon rollers and I'd not compatable with standard HK91/G3. The 23T and 30T are for the MSG90 and which also use 1/2 moon rollers, and I understand these are titanium coated. I believe that one is to shoot it suppressed, but I do not remember which is which. I think 1 and 9 are for use with HK11 or HK21?

    The "T" in relation to locking pieces stands for hardened steel, and has nothing to do with Titanium or titanium coatings. This info is propagated by a big time vendor who refuses to change his claims of "titanium" even when presented with evidence to the contrary.

    OK, I like learning new things and I would be grateful to see evidence to the contrary as referenced. When I contacted HK about these locking pieces years ago, I got the run around and could not get anyone to speak to me, so let's see what you have.

    Titanium is strong, but cannot be hardened like steel. Hardened steel is stronger and cheaper than titanium. Titanium is about 45% lighter than steel. So, if you weigh a "T" locking piece and compare it to a standard locking piece, you should have your definitive answer.

    Anyone with a T locking piece that wishes to part with is for a day, would be willing to run non destructive testing (SEM bases EDXA). If interested take this off line with a PM.

    Thank you for the clarification. No one said anything about tungsten and you do of course realize that the German word for "Titanuim" also begins with the letter T.

    Anyway, where are you getting your information? I am really interested in the proof.

    Wow, you completely edited and changed your post (I loved the left field reference to tungsten, why did you change it?! LOL!

    Anyway, I had understood titanium coated, not full titanuim alloy, so weight would be substantially identical.

    All that aside, you made me get the gun out and take it apart. You may be correct in taking a closer look at the locking pieces themselves and comparing them to regular HK91 locking pieces. They do not have the look of something which is Titanuim coated on closer inspection.

    So I will ask again, what is your source?

    Why, the internet, silly. You know they can't put anything on the internet which isn't true, right? Where'd you hear that? On the internet.
