Magnetic Trigger Mod

The following is for educational purposes only.  Firearms modifications should only be performed by a qualified gunsmith. 

Origin:  I found this when I installed an aftermarket grip and accidently over tightened the grip screw.  When I saw the new “hole” was directly under the trigger, and the wheels started spinning. 

The following describes a method for eliminating trigger creep on the Taurus RPC.

Materials and Supplies:
One 10-24 X 5/16 socket head set screw
1/16” punch
5/32” drill bit
3mm hex bit and driver, or 3mm Allen key

1. Remove the upper receiver from the lower and fully remove the push pins.

2. Remove the grip using the 3mm hex tool.

3. Use the 1/16” punch to remove the safety roll pin.  Turn the safety about ½ way between safe and fire, then wiggle the safety out the left side.

4. After the safety is removed, the entire fire control group will now lift out of the lower receiver.

5. Reinstall the nut and bolt without the grip in place as shown.  Tighten the bolt until it pokes through the polymer.

6. Remove the grip nut and bolt from the previous step.  Then clean the hole BY HAND using a 5/32” drill bit.  We just want to round the hole here, not remove any additional polymer.

7. Insert the setscrew into the lower from the bottom.  Firmly push in while threading the set screw into the polymer.  Screw it in until only about 1 thread is showing from the top side.

8. Reassemble the lower in the opposite order of disassembly.  If you have trouble getting the safety back in place, use your 1/16” punch to hold back the safety detent to make it easier.

9. After you have the lower reassembled WITHOUT the upper, it is time to set the depth of the setscrew:

A. Set the safety to the “fire” position.

B. Screw in the set screw until the hammer falls.

C. IMPORTANT Now cock the hammer a second time, then unscrew the set screw until the trigger resets.  Unscrew another ¼ - ½ turn to give it a little wiggle room.

10. Reassemble the upper, and while the firearm is still unloaded, fully test all safety systems and function.

Enjoy!

Hello! Hope everyone had a wonderful 4th!

I am looking for my first PCC and have zeroed in on the Daniel defense PCC but wanted to ask this group what they would recommend.

I’ve found a couple deals online, one from battlehawk that comes with a suppressor and a vortex red dot for $2100 and another deal that only comes with the vortex for $1700.

Are these deals worth it or should I just buy the gun for $1,500 and add my own red dot and suppressor?

The CZ scorpion is another PCC I like. I use a shadow 2 for competition and love CZ but I have no experience with either the DD PCC or the CZ.

Thanks in advance!

Switched and added some things. Not putting another cent into this, except for ammo of course..

Stribog sp10a3

Aems gold dot, arms republic comp, strike industries brace, magpul afg, hbi folding charging handle. Not shown, hbi short stroke buffer, trigger weight reduction spring, and improved bolt catch release (paddle)..

So proud of this thing. But, including a family pcc pic, my psa arv featuring wood furniture, a Romeo5, cmc trigger, and breek charging handle, and 35 round scorpion mags.

A few weeks ago I did a review of EP9 vs Kuna, now I added the VFM-9 to the mix. My big takeaway is this just made me like the EP9 even more lol.

I already planned to modify my 5” VFM-9, but I did this review initially in stock form. I bought the version with RMB (recoil mitigation buffer).

Recoil

The Kuna is king in recoil and it is not close. The Kuna really feels like a nailgun when shooting. The EP9 comes in second for felt recoil. The EP9, while not as completely soft as the Kuna, is still fairly soft and manageable. It is a different kind of impulse vs the Kuna, but it isn’t a straight punch. While the VFM-9 is much more like a straight punch. I wouldn’t say the VFM-9 recoil is bad, but it is clearly the worst and sharper than the EP9. The recoil itself in the VFM-9 isn’t much stronger, but the impulse is. The biggest difference between all 3 is the sharpness. You can do faster follow up shots with the Kuna due to it.

Ergos/Feel

In my first review I kept these pretty close between EP9 and Kuna, mostly on preference. Kuna is heavy and compact, EP9 is longer and much lighter. The Kuna feels good for me but someone who needs more room might enjoy the EP9 more. The VFM-9 is inbetween these two for weight and pretty similar size to the Kuna. Noticeably heavier than the EP9, slightly less than the Kuna. I have small hands and the VFM-9 handguard is great for me and the whole gun felt comfortable. The handguard did start to get warm though and if I didn’t have 3 PCC’s rotating, I could see the VFM-9 getting too hot the fastest out of the three (all shooting was suppressed). It does cool down pretty quick at least.

Controls

The Kuna still has the best controls, but the VFM-9 actually has pretty nice controls too. This is the one area the EP9 is just straight dogshit in lol. The Kuna everything feels top tier and like you have a high end firearm. Everything on the VFM-9 is slightly worse, except the mag release. It has the best mag release out of the 3 by far, actually so good. The safety lever is also really good on the VFM-9, only reason it isn’t better than the Kuna is 90 degrees vs Kuna being like 35 degrees, but it is smoother. The rear and the front charging handle on the VFM-9 are ok but not great, and still better than the EP9. The charging handle on the Kuna is the smoothest and best. VFM-9 has ambi controls just like the Kuna, just the left hand bolt catch is slightly worse (it is just a nub). While the EP9 has no ambi, and my biggest gripe is having the charging handle on the same side as the bolt catch, which to me is just dumb.

The trigger is the one weak point on the VFM-9 and the worst out of the 3. I actually think the EP9 trigger is ok, I have no need to replace it. I need to replace the VFM-9 trigger (already did lol). The Kuna has the best trigger easily.

Gas

I think the VFM-9 had the worst gas. Obviously the Kuna will be the least gassy, and more pleasant suppressed. As I said in my previous review, since I switched to Blazer Clean Fire Suppressor 147gr ammo, the gas doesn’t really both me much on any of the guns. For gas it is Kuna, then a big gap, EP9, and VFM-9. It just feels like the VFM-9 spits shit a lot and I get dirty shooting it. I switched cans when testing this since obviously the Milkman will have the least gas.

Brace

In my previous review I mentioned while the Kuna brace looks uncomfortable, it is surprisingly fine to shoot. However, my mind changed a bit today because I shot a mag of Federal HST 147gr and yeah, the Kuna brace kinda sucks lol. With soft shooting ammo it isn’t bad at all but with the HST I really felt it. The EP9 has the most comfortable brace (with the SBA3 version). The VFM-9 brace is noticeably worse than the EP9, but isn’t bad overall and better than the Kuna brace (and better than the EP9 blade). I am still going to replace the brace on both the VFM-9 (bought a SBA5 brace) and the Kuna (bought a 1913 brace).

TL;DR

Overall this just re-affirmed to me that the Extar EP9 is the budget king, with its biggest downside being trash controls, but otherwise it is pretty top tier in other aspects imo. The weight is a big advantage, and it shoots soft enough to be overall pleasant. The Kuna is the best in recoil, gas, and controls, but it needs a different brace, and everything comes at a premium price. The VFM-9 is a cool gun with good controls, and overall good value, just a bit worse to shoot recoil wise, and worse reliability with ammo.

So if you want a gun that just works and is budget friendly, esp for home defense, get the EP9. I would get the VFM-9 if you specifically want an AR9, and want access to AR9 upgrades (which is why I got it), but not for home defense due to ammo feed issues. To me the VFM-9 is better than the EP9 as a fun range toy, but worse for a do it all reliable gun. The Kuna is just the premium option, and it is clearly better in a lot of ways, but obviously costs a lot more, and isn’t without some downsides. Also the Kuna with BOE Incolite 9M is ridiculously quiet and people are impressed with it every time lol.

Some additional points on VFM-9 ammo

I had some feeding issues with the VFM-9 (all flat nose ammo), and a few times it failed to cycle, which I think may be due to the ammo since it is light loads. I don’t know enough about the short stroke buffer to know if that is the cause, but I will be switching to an A5 buffer. That makes me hesitant to use or recommend it for home defense, but I did buy it to be a range toy specifically.

I replaced the buffer to an A5 buffer and had zero cycling issues, and no feeding issues with Blazer Clean Fire, which is flat nose, but Federal Syntech 150gr would not feed at all. So I do think the short stroke buffer it comes with stock was giving cycling issues with the lighter loaded ammo. Again I don’t know much about the short stroke buffer or why it is used, but just my experience, I would not recommend it. Also the SBA5 brace was a nice improvement and I highly recommend. Outside of these issues I do think it is a nice gun overall. I am happy with my VFM-9 now as a range toy, and with FRT, it is super fun.

testing 9mm vector sdp with frt! this one actually runs great! previously i used double tap binary, and big brrt,. but this frt runs exactly like its supposed to!

I want to get a Plan B setup on my Jakl 9 and set my Obsidian 9 up to be able to attach to it. Is this everything I would need?

I can score this for $300 at my LGS. Used but never fired. How does this function for a lefty?

Finally picked up a Kuna and decided to do a simple build, only the necessities so far. Suggestions are welcome! Mainly looking for brace alternatives, the factory one is not the most ergonomic.

Picked up a .45 ACP Ruger LC Carbine right before VA completely shat the bed. I'll be running to the range to test it out promptly 🤘

We want to introduce ourselves to the world and say thank you to the many of you here that have supported our small 5 man team. I will be open to questions here, I want to know what the people want, what you guys think the good and bad, because we believe we have the team (although tiny) to make the perfect PCC. We have received amazing reviews from you all and have even heard stories of our BlackJack replacing some of your builds from other the big guys, which is flattering. However, we want to push to be the best one day, and we have a long road ahead of us.

I recently purchased a Panzer Arp9 and i noticed it has little but of play, has anyone experienced something like this ?

Have a 90 LP in my AP5-P. Went through 115 and 124 ammo today. Running an Omega 9k with a Leber V2 and it runs perfect when going suppressed with the FRT but without the can it wont cycle very well with the FRT. I don’t plan on shooting it much without the Omega 9k but I just wanted to see how it would go. Anybody have any input on why it won’t cycle that well?

Attached are photos of my Mat9k build (the last photo is unedited)

My MAT-9K / Matador 9 Colt build is almost finished, but I’m trying to resolve a bolt catch / bolt release issue before I take it out to shoot.

Important Context: I just had the upper receiver Cerekoted

The issue is that the bolt catch seems to engage correctly, but it does not release/reset reliably. When I pull the charging handle back and use the bolt hold-open/release control, the bolt catches like it should. But when I press the top of the bolt release/catch to drop it, the bolt does not go forward like it should.

I’ve been working the charging handle back and forth to try to loosen things up, and that has helped quite a bit. I’ve also cleaned everything with CLP and oiled it. It feels noticeably better than it did at first, but the bolt still does not reliably release when I press the bolt catch/release.

Build details:

•	Upper: Matador Arms MAT-9K  
•	Lower: Matador 9 Colt-pattern lower  
•	Magazine: Metalform 9mm 32-round SMG mag  
•	Brace: A3 Tactical modular telescopic brace  
•	Brace attachment: Gear Head Works Tailhook  
•	Grip: MDT Pistol Grip Elite  
•	Trigger: Geissele SSA-E currently installed may change to SSA  
•	Optic: Holosun 510c  
•	Suppressor: Dead Air Wolfman

Since only the upper was Cerakoted, I’m wondering if the added coating thickness on the upper is causing some kind of interference between the upper, bolt/BCG, and bolt catch. It seems like the bolt catch is holding the bolt open properly, but then either the catch is not dropping cleanly or the bolt is binding against it under pressure.

I don’t want to start filing or sanding blindly. I’d rather diagnose the actual contact point first and fix it correctly.

Has anyone run into something similar with a with a freshly Cerakoted upper causing bolt catch interference? Any advice on what to try first would be appreciated.
