Okay, thanks. I thought there might be bigger markdowns to justify picking up a backup.

I’m not seeing them. What section are they in?

Just think what he could have done with a JP-5!

I never changed the trigger. As I posted in another thread, the Radian Talon 45/90 ambidextrous safety works well with the JP trigger in my JP-5. The only odd development is that I am now able to engage the safety with the hammer down with the 45 degree selector set up. I was never able to do that when I had the JP 90-degree safety selector installed. I’ve seen people post here that JP says the Radian Talon 45/90 ambidextrous safety will not work with the JP trigger. They never told me that. The guy I spoke with at JP said he didn’t know, and that I’d have to try it to find out. Since I already had a Radian Talon 45/90 ambidextrous safety, I went ahead and tried it, and it worked for me. The only thing it cost me was a new set of JP oversized anti-walk pins. And I now have to to be aware of whether the hammer is down or not without trying to engage the safety as a way to check.

I tried that, but I was only able to get one screw out. I stripped the others. The guy at JP recommended a certain drill bit size that they use there to break the screw heads off. I can’t remember the size, but it actually worked well.

For what it’s worth, I had to take the trigger group out in order to get the JP safety out on my JP-5. I called JP, and they said I might have to do that, and they were right. The problem is that they Loctite the hell out of the anti-walk pins, and I had to destroy them to free up the trigger group to get it out from under the JP safety. So I had to order new JP oversized anti-walk pins for the trigger group reinstall. The guy I spoke to at JP was extremely helpful, so you might want to give them a call if you have any questions about your next steps. In the end, it was all worth it for me because I LOVE the Radian Talon’s 45 degree safety switch for stock-on-belt starts.

Did you remove the trigger group?

I had a match-killing failure to eject using 130 PF rounds with a 70-degree lock piece. I went back to the 80-degree lock piece and haven’t had any problems. You might be tempting fate with 60-degree lock piece for PFs in the 130s. What OAL are you loading the HAPs to? Several years ago, I called Hornady and they said to use XTP data for the HAPs. They recommended 1.060” for the XTPs, which seemed rather short to me. It’s the only reason I shied away from the HAPs at the time. A couple of months ago, I found some of of the unloaded HAPs in my workshop, so I loaded a few without changing my 1.120” FMJ seating die, and they came out to 1.085”. I worked up a ladder with N340 from 4.0 to 4.6, and to make a long story short, 125 grain HAPs with 4.3 grains of N340 at 1.085” averaged 132.5 PF in my JP-5, and they felt great with the 80-degree lock piece. Quiet power with smile-inducing accuracy is the best way to describe it. I might get some 124 grain “competition style” bullets from Everglades (which look like a HAP copy, but are .355” and 124 grains instead of the HAP’s .356” and 125 grains) and make them my new match ammo.

Eley has 115, 124, and 147 for pistol, and 115 and 124 for PCC: https://www.eleyammunition.com/minor9_competition_pistol_pcc_rounds/

Update: since I already had a Radian Talon 45/90 ambidextrous safety, I went ahead and attempted to install it in my JP-5 with the JP trigger. I had to remove the JP trigger to get the JP safety out, but once I did, the Radian safety went right in. For me, the 45 degree safety selector makes a world of difference when disengaging the safety from the stock on belt position. The only odd development is that I am now able to engage the safety with the hammer down with the 45 degree selector set up; I was never able to do that with a 90 degree selector. But other than that, the Radian Talon 45/90 ambidextrous safety works well with the JP trigger in my JP-5.

I use Glock 17 standard-size 17-round magazines on classifiers to make reloading quicker and easier. I have two pouches on the weak-hand side of my PCC belt to draw them from. Reloading becomes just like it is with a pistol, which I had a lot of experience with prior to starting with PCC, so it feels smooth and natural for me.

Do you know if the Radian 45 degree safety selector will work with the factory JP-5 trigger?

Sage advice. And thanks to everyone else, too. I’ll put the 80 degree lock piece back in and see how it goes.

Lock piece question: At the start of a stage during a match recently, I had what I believe was a case ejection failure after the first shot, causing a jam up from the next stripped round. Fumbled attempts to get the bolt to close with the timer running caused more rounds to collect in the receiver, and by the time I got the gun fully cleared, the stage was destroyed and the match was lost. I had switched to a 70 degree lock piece because it made recoil with my 124 grain 130 PF loads almost nonexistent, but would going back to the 80 degree lock piece make a repeat of this ejection problem less likely in future matches?

Yes.
