I just called HK USA’s customer service line (706-701-5554) to ask about what locking piece ships with a new SP5k. Got the answer: 100 degree.

I then talked to him about running suppressed and the warranty of using aftermarket LPs due to the fact that I cannot find HK LPs in stock.

He told me it’s my lucky day, he couldn’t believe it, #28/80 degree HK locking pieces are in stock! $167 out the door for me.

Happy birthday to you and me!

(Hopefully this is the right forum for this? Apologies if it is not. It’s suppressor related, though.)

op, you probably know this, but, the 80* lp is only for suppressed + subs.. don't bother changing it otherwise.

the advise to ALWAYS change locking piece before you suppress a k is from back in the day when they all shipped with a 110* lp.
I do know this, but thanks for making it clear to all. I only shoot suppressed, with subs if I can.

I do find conflicting info about shooting with the stock 100 degree with suppressed/subs. The rep I talked to says it’s best to switch to 80, but? Whatever, but not that much cash.

For those who don’t know, these factory HK #28/80 LPs are hard to find!

Forgot to add I’m shooting Federal Syntech 150g Action Pistol.

Since @bystok you’re an HK Certified Armorer, what’s the official HK story on shooting the above ammo in a K + suppressor with 100 degree LP? I see so much variable info on that point (clones=yes, HK=no, All need it, etc etc etc).

Even if you ran subs for thousands of rounds on the 100*… I doubt It’d hurt anything, but at that point you are spending a ton on ammo and are obviously running that ammo a lot, so why not use the proper piece. Doing a mag probably isn’t the end of the world.

I probably would NOT run subs suppressed on a 110*.. like ever..

I prefer to just not shoot subs out of my k. I have a SD for that.
